”Companiile care introduc big data și analitică în operațiunile lor indică procente de productivitate și profitabilitate cu 5% 6% mai mari decât cele ale colegilor lor”. În Big Data există multe întrebări valoroase, fără răspuns. Provocarea este aceea de a găsi modalitatea de a separa semnalul de zgomot din date, determinând

”Cunoașterea este profit” pentru acele firme care utilizează soluțiile analiticii predictive big data pentru a reduce riscurile, a lua decizii înțelepte, a crea experiențe diferențiate și mai personale pentru clienți.

Răspunsurile se află în date – dar numai dacă companiile le caută.

Atunci când plănuiți să utilizați analitica, aveți două opțiuni: fie utilizați pachetele de analitică universale, fie construiți aplicații de analitică la comandă.

După cum afirmă raportul McKinsey, pachetele de analitică universale pot fi rentabile și mai rapid de instalat decât modelele la comandă, ajustate. Dar

Gabriel Ciuloaică

Reactive programming Software consultant

Marius Danciu

Asynchronous programming in Scala Software architect at IBM

What is Scala ?

• • • •

A hybrid Func>onal & OOP language Invented by Prof. Mar>n Odersky @ EPFL First released in 2003 Runs on JVM

Why Asynchronous?

• CPUs are not ge"ng significantly faster, BUT we’re ge"ng more and more CPU cores • So2ware need to exploit mul>-­‐cores in order to gain performance and scalability.

• Asynchronicity does not guarantee scalability ! … you need to avoid or defer as much as possible blocking calls.

• We need responsive systems and for this we need be[er use resources.

What is asynchronicity ?

• Simply put -­‐ The caller thread does not wait for a response Syncronous

def compute() : Response = { … }

Asyncronous

def compute(f : Response => Unit) { … }

Programming models • Threads -­‐ Dealing with threads and parallel computa>ons is hard to do it right. Very error prone.

• Actors – A very simple messages passing architecture inspired by Erlang.

• Non blocking Futures & Promises – React when results are available.

• Async & Await – Brought in Scala via Macros

Actors • Star>ng Scala 2.11 the Scala actors will be deprecated and you should use Akka actors. import akka.actor.Actor import akka.actor.Props class MyActor extends Actor { def receive = { case "test" ⇒ println("received test") case “echo" ⇒ sender ! “echo” case _ ⇒ println("received unknown message") } }

import akka.actor.Actor import akka.actor.ActorSystem import akka.actor.Props class MyActor extends Actor { def receive = { case "test" ⇒ println("received test") case “echo" ⇒ sender ! “echo” case _ ⇒ println("received unknown message") } } val system = ActorSystem("mySystem") val myActor = system.actorOf(Props[MyActor]) myActor ! “test”

• Hot swapping – build state machines class HotSwapActor extends Actor { import context._ def angry: Receive = { case "foo" ⇒ sender ! “Oh man, I need a drink." case "bar" ⇒ become(happy) } def happy: Receive = { case "bar" ⇒ sender ! “Now I need two drinks !" case "foo" ⇒ become(angry) } def receive = { case "foo" ⇒ become(angry) case "bar" ⇒ become(happy) } }

Futures and Promises • Wait ! Java has Futures … why do we need Scala futures ?

Future<Integer> future = ... ; Integer result =

future.get();

• 2 BIG Reasons • This is blocking • They do not compose

• Blocking Futures Thread 1

Thread 2

• Polling Futures Thread 1

Thread 2

Callbacks val f1 = future { Monad is a container type of kind * -­‐> * // some computation with the contract: } f1 f1 f1

def unit[T](t: T) : M[T] def map[A, B](f: A => B) : M[A] => M[B] onSuccess { v => println(v)} def flatMap[A, B] (f: A => M[B]): M[A] => M[B]

onFailure { v => println(v)} onComplete {t => … }

BUT ! Futures are Monads so we can: -­‐ chain them -­‐ aggregate results in non blocking ways -­‐ transform results -­‐ gracefully handle errors

val userFuture = future { getUserDataFromSql() } val activityFuture = future { getUserActivityFromCassandra() } val results = for { user <- userFuture activity <- activityFuture } yield aggregate(user, activity) results onSuccess { case r => println(“Retrieved " + r) }

Using map, flatMap, filter etc. recoverWith/fallbackTo combinators In many cases you do not need to use callbacks.

Promises • Write once handles. Promises provide a future that is completed only when we complete the promise. def any[T](fs: List[Future[T]]): Future[T] = { val p = promise[T] for { f <- fs } { f.onComplete(v => p.tryComplete(v)) } p.future }

Async & Await • Non blocking computa>ons with Futures def combined: Future[Int] = async { val future1 = slowCalcFuture val future2 = slowCalcFuture await(future1) + await(future2) }

Remember • Scala & Akka stack provide extremely powerful abstrac>ons and infrastructure for non blocking parallelism and concurrency.

– Actors – Futures and Promises – Async & Await

Proper Web Automated Testing • UI • Open Source

Selenium 101

1

Write the first tests – Heuristic approach “Don’t worry just write the first pieces of code” How to test?

• Intent – Action • Map your manual testcases to the automated ones • It’s ok to mess up code at first, but don’t mess up the business logic

Selenium 101

2

What do you mean?

Selenium 101

3 Â

Given the simple testcase: (We will call this the “intention”) Steps: 1. Open IE 2. Navigate to http://google.ro 3. Search for the “The Automated Tester” string Expected Result: 1. After step 3, verify the search title matches your search word.

Selenium 101

4

The automated test: (We will call this “the action”) • Open IE and navigate to http://google.ro • Wait and confirm proper page loading • Select the search field (DOM name = “q”) • Type in the search word • Make sure the search title matches the search word

Selenium 101

5

Dude, your automated test does not really have a structure

That’s because …

We haven’t decided an architecture just yet… We’ll do it soonish!

Selenium 101

6

Teh codez… […] namespace mySeleniumNETDemoInitial { class Program { static void Main(string[] args) { // Start writing some code, no matter what IWebDriver driver = new InternetExplorerDriver(@"C:\SeleniumDrivers\"); driver.Navigate().GoToUrl("http://google.ro"); IWebElement myField = driver.FindElement(By.Name("q")); myField.SendKeys("The Automated Tester"); myField.Submit(); Assert.True(driver.Title.IndexOf("The Automated Tester") > -­‐1); Console.WriteLine("Success in entering Google RO page"); driver.Close(); } } }

Selenium 101

7

Heuristic part now officially over! Stop all coding! Start thinking!

Where are we?

• Have the automated test functioning [done] • Make your manager happy [done] • Map your testcases to the automated ones [not started] • Style guide and code best practices [not started] • Test API and architecture [no way]

Selenium 101

8

Let’s take care of these tasks step by step now…

• Map your testcases to the automated ones [done] namespace mySeleniumNETDemoInitial { [TestFixture] class Test_Google { IWebDriver driver; [SetUp] public void Setup() { driver = new InternetExplorerDriver(@"C:\SeleniumDrivers\"); } [TearDown] public void Teardown() { driver.Close(); } [Test] public void TestSearchGoogle() { […] // Not so pretty code from iteration 1 goes here } } }

Selenium 101

9

Let’s take care of these tasks step by step now…

• Style guide and code best practices[done] Remember our initial test method? static void Main(string[] args) { // Start writing some code, no matter what driver.Navigate().GoToUrl(Constants.TEST_PAGE_URL); // I want to fail if the page loads in more than 10 seconds IWebDriver driver = new InternetExplorerDriver(@"C:\SeleniumDrivers\"); driver.Manage().Timeouts().SetPageLoadTimeout(new TimeSpan(0, 0, 0, 10)); driver.Navigate().GoToUrl("http://google.ro"); IWebElement myField = driver.FindElement(By.Name("q")); IWebElement myField = driver.FindElement(By.Name("q")); myField.SendKeys("The Automated Tester"); myField.SendKeys(Constants.SEARCH_TERM); myField.Submit(); myField.Submit(); Assert.True(driver.Title.IndexOf("The Automated Tester") > -­‐1); Assert.True(driver.Title.IndexOf(Constants.SEARCH_TERM) > -­‐1); Console.WriteLine("Success in entering Google RO page"); Console.WriteLine(Constants.LOAD_SUCCESSFUL_MSG); driver.Close(); } driver.Close(); IWebDriver driver = new InternetExplorerDriver(Constants.IE_DRIVER_PATH);

Console.Out.Close();

Selenium 101

10

Let’s take care of these tasks step by step now…

• Test API and architecture [done] • We want to move all the constants to a separate class // XXX: Lets decouple this by moving constants into a separate class file static class Constants { […] public const string LOAD_SUCCESSFUL_MSG = "Success in entering Google RO page"; public const string TEST_PAGE_URL = "http://google.ro"; public const string IE_DRIVER_PATH = @"C:\SeleniumDrivers\"; […] }

We now got rid of the ugly hardcoded strings, and we have a clear location for all of them

•

Selenium 101

11

Let’s take care of these tasks step by step now…

• Test API and architecture [done] • We want to create a helper method for searching any strings in any fields public void Search(aField, aTerm) { […] // Paste search code here }

• What a cool piece of re-usable code we just wrote

So after all this workâ&#x20AC;Śwe are still not done?

Selenium 101

So after all this work…we are still not done?

No, sorry. What we want further is: • A change in the application under test is to be reflected in one change in the test API, and only one • Map test API to reflect functionalities/services in the webapp, instead of having just helpers and algorithmics • No duplication of Selenium API, NUnit API or whatever API calls

Selenium 101

Page Objects Pattern

Selenium 101

18

So after all this workâ&#x20AC;Śwe are still not done?

Consolidates the code for interacting with any given UI Element Allows us to model the UI in the tests (UI Mapping) Exposes methods that reflect the things user can see and do

Page Objects Pattern

Hides the detail of telling the browser how to do those things

Selenium 101

19 Â

Page Objects Pattern The Model

Selenium 101

20 Â

Page Objects Pattern The API

public class LoginPage { public HomePage loginAs(String username, String password) { // ... clever magic happens here }

public LoginPage loginAsExpectingError(String username, String password) { // ... failed login here, maybe because one or both of the username // and password are wrong }

public String getErrorMessage() { // So we can verify that the correct error is shown } }

Selenium in .NET

21

Page Objects Pattern The Tests The tests should be responsible for making assertions about the state of a page. For example:

public void testMessagesAreReadOrUnread() { Inbox inbox = new Inbox(driver); assertTrue(inbox.isMessageWithSubjectIsUnread("I like cheese")); assertFalse(inbox.isMessageWithSubjectIsUnread("I'm not fond of tofu")); }

Selenium 101

22

Page Objects Pattern Summary • The public methods represent the services that the page offers • Try not to expose the internals of the page • Generally don't make assertions • Methods return other PageObjects • Need not represent an entire page • Different results for the same action are modelled as different methods

Selenium 101

23

Test design practicalities (in short) • Locator strategy • ID s • HTML • CSS Selector • DOM Lookup / XPath

Selenium 101

24

Test design practicalities (in short) • Parallelization • Problem: Selenium is slow compared to Unit tests • Solution: Run tests in parallel • Prepare for that s • Atomic and autonomous tests • Group tests in small batches • Be descriptive • Use a test runner

Selenium 101

Agenda

What we will cover: Evolution of SAP Technologies over the past decades, current challenges and future outlook

’82 – ’91: The SAP R/2 era

• Real-time ERP solution running on enterprise mainframes • Integrated many of an enterprise’s functions: accounting, manufacturing, supply chain management etc.

• 2-tier architecture with terminal based user interface

’92 – ’01: SAP R/3 & Dynpro technology

• • • •

SAP R/3 brings ERP solutions to the desktop computer 3-tier Architecture Local Computer The advent of Dynpro technology Any Dynpro(Dynamic Program) consists of - Screen layout - Corresponding flow logic

SAP Application Server

RDBMS

Flow logic

Screen Layout

Flow logic

Dynpro creation

• Dynpro definition created by developers using Screen Painter tool of the Netweaver Application Server • Layout metadata stored in underlying DB Local Computer

SAP Application Server

RDBMS

Screen “Painting”

Screen Layout metadata

Dynpro metadata

How does Dynpro rendering work?

• Rendering possible with a SAP GUI client installed on local computer: - TCP connection between SAP GUI client and application server - The client retrieves Dynpro definition and handles the rendering of the screen on the local computer

Local Computer SAP GUI client Dynpro metadata

SAP Application Server

RDBMS

SAP Portal

• Around year 2000: mySAP Portal - Browser based single point of entry to SAP enterprise applications - Role based personalizaion - Single Sign-On

• Technically based on Dynpro rendering in web browser(SAP WebGUI)

SAP WebGUI: Dynpro rendering in Web Browser

• Made possible by introducing a “middleware” into the R/3 3-tier architecture: the Internet Transaction Server (ITS) • Using a predefined template, the ITS compiles the Dynpro layout metadata into HTML, to be rendered in any web browser

Modern UX requirements

Modern end-user expectations are shaped by intuitive touchscreen devices and software they use privately, raising the bar for the applications they use at work " Customers are increasingly stating that user experience (UX) is the differentiator, not features and functions " Complex and feature-rich experience must be replaced by simplicity, intuitiveness, and mobility

“The world is ready for the consumer-grade enterprise” (Paul Maritz, former VMWare CEO)

Status Quo. What customers say about SAP solutions

• SAP business solutions use an estimated 300,000 screens ( about 220,000 of which are Dynpros ) • Designed Comprehensive for different product lines, numerous product versions, Too many – can handle different vertical industry requirements, etc. fields everything Integrated – everything we need in one place Helps me run my business better

Too many screens

Too many clicks

" Flexible business solutions, however not optimized for streamlined user experience

SAP UX Strategy Goal: “ENABLE” Enable customers to improve UX of SAP solutions themselves • SAP Screen Personas

ENABLE Enable personalization of existing SAP solutions for customers. Aims at: • Ease of use - Simplify interfaces - Personalize for specific needs

• Increased productivity - Pre-filling of default values - Task recording & automation

• UI redesign, branding a.s.o.

Challenges: • Large number of Dynpro based solutions (tightly coupled with application logic, difficult to change) • Personalization usually requires technical knowledge

SAP Screen Personas

What is it?

• State-of-the-art SAP technology (v1.0 released Dec. 7th, 2012) for (re)designing Dynpro screens of existing SAP applications

Main Features • Quick and easy screen personalization performed by customer • Easy to use drag-and-drop interface • Technical/programming knowledge not a necessity

How does it work?

• Netweaver Kernel 7.21 # new interface through which screen layout decriptions can be retrieved in the form of an Object Model @(Re)Design-Time Personas Screen Editor • Client-side web-based editor that enables changing of the Object Model • New “flavors” stored on the server-side in the NW Personas Add-On

Local Computer SAP GUI

Browser Dynpro object model

New Flavor

Personas Add-On

SAP Application Server

RDBMS

ITS

How does it work?

@Runtime • Changes are applied to Screen Object Model before rendering the Screen • 2 types of Personas “output”: HTML and Silverlight

SAP Technology Services Conference http://www.slideshare.net/peterspielvogel/sap-screen-personastechnologyserviceconfmarch2013

SAP UX Strategy Goal: “RENEW” Renew existing applications, improving user experience: • WebDynpro

WebDynpro

What is it?

• Application Development tool • Runtime environment Built to become the de facto standard SAP UI technology: • Cut implementation time & cost • Focus on business functionality rather than technical details of UI development Main Features: • Declarative approach to user interface development • Client abstraction • Ease of use • Modularization into components for reuse on a higher(functional) level • Strong MVC-oriented application structure

Declarative approach

• Tell the application what to do, rather than how to do it “Minimize coding, maximize design” • Declaration of: - - - -

Data structures Screen layouts Navigation paths among screens (“views”) …

SAP UX Strategy Goal: “NEW” Provide consumer-grade UX for new applications • SAP UI5 • SAP Netweaver Gateway

SAP UI5 What is it?

• “Enterprise-ready” JavaScript library - optimized for building business applications for desktop and mobile platform • based on open source and open standards like JQuery, HTML5, JavaScript, CSS, LESS and others

SAP UI5

• Built around JQuery - Can be viewed as an abstract layer add-on to JQuery

• Adds additional controls typical for business application development • Optimized for consumption of data in JSON, XML format exposed through OData services by various systems: - SAP Application Server ABAP - HANA Cloud Platform - SAP Application Server Java - SAP Netweaver Gateway - SAP HANA Cloud Gateway or SAP HANA itself

Connectivity to SAP backend • SAP business functionality exposed through various types of technical interfaces: RFC, BAPI, MDX …

• Integration task is difficult due to lack of homogenity The solution – Netweaver Gateway: • Integration Middleware that provides existing business functionality through new interfaces based on market standards " Connectivity to SAP applications using any programming language by leveraging REST services and OData/ ATOM protocols

SAP HANA •

SAP’s own In-Memory DB (and much more)

SAP HANA is..

...an in-memory database: • Can be used as DB under a SAP NetWeaver 7.40 just like Oracle DB or IBM DB2 • Can be queried using standard SQL interface # the entire SAP Business Suite can be set up to run “on HANA” without any further adjustments •

Typical IMDB properties shared by SAP HANA: - Loading&Holding of data in memory

Client

SAP Netweaver Application Server

- Usage of data compression mechanisms - Performance improvement through column based storage

- Massive parallelization potential (separate query execution across multiple cores)

However, HANA is much more than “just” a typical IMDB

RDBMS HANA

SAP HANA

•

Several optimized engines on top of column store to boost performance

•

Several other external interfaces in addition to Standard SQL Interface: 1. SQLScript - - -

Enhancement of SQL syntax Parallel execution Imperative logic

2. R connectivity (statistical processing, data mining algs. …)

3. BFL (Business Function Library) 4. MDX " Environment that enables the development of very powerful DB-layer logic

Why would this be necessary in the database layer?

Figure taken from openSAP lecture "Introduction to Software Development on SAP HANA" (Thomas Jung, 2013)

Code Pushdown

• • •

Several phases of migrating to a HANA-based system landscape: “side-car” approach, HANA for OLAP(10x-100x faster),…

All come with increasing performance improvements However, full potential can be obtained by adjusting application layer logic: “Code Pushdown”

Figure taken from openSAP lecture "Introduction to Software Development on SAP HANA" (Thomas Jung, 2013)

SAP HANA Native Apps

•

Up until now: “Classical” 3-tier architecture: - DB- and application-layer are separated - Client handles rendering of user interface

However, leveraging the full potential for real-time analytical processing with SAP HANA requires a break of this architecture ! HANA is a complete appliance • What is the separate application tier needed for? # Nothing • Are clients powerful enough to handle the rendering? # Yes

Cateva concluzii: 1. S-a pornit „de sus” în industria IT 2. În prezent IT este o industrie „pe val” 3. Pentru viitor este vitală o viziune cu rezultate: – transformarea de la outsourcing la produse proprii – dezvoltarea angajaţilor

4. Firmele mici par mai flexibile

WCF ◦ simplifies development of connected applica>ons ◦ uses a service-­‐oriented programming model ◦ supports many styles of distributed applica>on development ◦ provides a layered architecture ◦ it’s channel architecture provides asynchronous, un-­‐typed message-­‐passing primi>ves ◦ has protocol facili>es for secure, reliable, transacted data exchange and broad choice of transport and encoding op>ons

!

A few new concepts above. Let’s exemplify!

!

Contracts ◦ are next to that of Applica>on layer ◦ developers directly use contracts to develop services

w w w . a c c e s a . e u

1

!

Service contracts ◦ describe the opera>on that service can provide i.e. given a service that knows the temperature of the city based on the zip code will define and expose this func>onality via a service contract

w w w . a c c e s a . e u

1

!

Data contracts

◦ describe a custom data type which is exposed by the service to the client ◦ simple data types like int, string are iden>fied by the client because it is already men>oned by default in the service XML schema defini>on ◦ only custom created classes or data types cannot be iden>fied by the client by default i.e. an Employee data type(good prac>ce: conceptually each class should define a type, and subclasses should define subtypes) ◦ using a data contract we can make a client aware that we are using an Employee data type for returning or passing parameter to a method defined in the service contract

w w w . a c c e s a . e u

1

!

Message Contract

◦ default SOAP message format is provided by the WCF run>me for communica>on between Client and service ◦ if it is not mee>ng your requirements then you can create our own message format ◦ this can be achieved by using Message Contract a[ribute

w w w . a c c e s a . e u

1

!

Policies and Binding

◦ specify condi>ons required to communicate with a service i.e. security requirements to communicate with service or the protocol and encoding used for binding

w w w . a c c e s a . e u

1

!

Service Run>me

◦ contains the behaviors that occur during run>me of service ! Thro[ling Behavior-­‐ Controls how many messages are processed ! Error Behavior -­‐ Specifies what occurs, when internal error occurs on the service ! Metadata Behavior -­‐ Tells how and whether metadata is available to outside world ! Instance Behavior -­‐ Specifies how many instance of the service has to be created while running ! Transac>on Behavior -­‐ Enables the rollback of transacted opera>ons if a failure occurs ! Dispatch Behavior -­‐ Controls how a message is processed by the WCF Infrastructure

◦ are advanced techniques which are used to provide custom service behavior

w w w . a c c e s a . e u

1

!

Messaging

◦ is composed of channels ◦ a channel is a component that processes a message in some way, for example authen>ca>ng a message ◦ a set of channels is also known as a channel stack ◦ channels are the core abstrac>on for sending message to and receiving message from an Endpoint ◦ Channel categories: ! Transport Channels -­‐ handles sending and receiving message from network. Protocols like HTTP, TCP, name pipes and MSMQ ! Protocol Channels -­‐ implements SOAP based protocol by processing and possibly modifying message i.e. WS-­‐Security and WS-­‐Reliability

w w w . a c c e s a . e u

1

!

Ac>va>on and Hos>ng

◦ services can be hosted or executed, so that it will be available to everyone accessing from the client ◦ WCF service can be hosted by following mechanism ! IIS -­‐ Internet informa>on Service provides number of advantages if a Service uses H[p as protocol. It does not require Host code to ac>vate the service, it automa>cally ac>vates service code ! Windows Ac>va>on Service -­‐ In addi>on to HTTP based communica>on, WCF can also use WAS to provide message-­‐based ac>va>on over other protocols, such as TCP and named pipes ! Self-­‐Hos>ng -­‐ WCF service can be self hosted as console applica>on, Win Forms or WPF applica>on with graphical UI ! Windows Service -­‐ WCF can also be hosted as a Windows Service, so that it is under control of the Service Control Manager (SCM)

w w w . a c c e s a . e u

1

!

Endpoint communica>on ◦ A WCF Service is a program that exposes a collec>on of Endpoints ◦ Each Endpoint is a portal for communica>ng with the world ◦ All the WCF communica>ons are take place through an endpoint ◦ End point consists of three components(ABC): ! Address ! Binding ! Contract

w w w . a c c e s a . e u

1

!

Endpoint Address ◦ Basically URL, specifies where this WCF service is hosted ◦ The client will use this URL to connect to the service i.e. h[p://localhost:8090/MyService/SimpleCalculator.svc

w w w . a c c e s a . e u

1

!

Endpoint Binding

◦ Describes how a client will communicate with service as there are different protocols available for the WCF to communicate to the Client ◦ A binding has several characteris>cs: ! Transport -­‐Defines the base protocol to be used like HTTP, Named Pipes, TCP, and MSMQ ! Encoding (Op>onal) -­‐ Three types of encoding are available: Text, Binary, or Message Transmission Op>miza>on Mechanism (MTOM -­‐ is an interoperable message format that allows the effec>ve transmission of a[achments or large messages (greater than 64K)) ! Protocol(Op>onal) -­‐ Defines informa>on to be used in the binding such as security, transac>on or reliable messaging capability

w w w . a c c e s a . e u

Endpoint Binding

w w w . a c c e s a . e u

!

Endpoint Contract ◦ Defines the collec>on of opera>ons that specifies what the endpoint will communicate with outside world ◦ Usually name of the Interface will be men>oned in the Contract, so the client applica>on will be aware of the opera>ons which are exposed to the client ◦ Each opera>on is a simple exchange pa[ern such as one-­‐way, duplex and request/reply

w w w . a c c e s a . e u

Endpoint Communica>on Summary

w w w . a c c e s a . e u

!

Endpoint Configura>on ◦ Can be done usually in the applica>on’s XML configura>on file ◦ Also support dynamic configura>on at run>me

w w w . a c c e s a . e u

!

Programming a Service Contract ◦ Requires providing the service contract interface and it’s implementa>on

w w w . a c c e s a . e u

1

!

Programming a Data Contract ◦ Used when the service exposes custom data types in order to expose them to the client applica>ons

w w w . a c c e s a . e u

1

!

Programming a Message Contract ◦ On Some cri>cal issue a developer will also require control over the SOAP message format ◦ In that case WCF provides Message Contracts to customize the message as per requirement

When you use this EmployeeDetails type in the service opera>on as parameter WCF will add extra header call 'EmpID' to the SOAP envelope and also add Name, Designa>on, Salary, Loca>on as extra member to the SOAP Body.

w w w . a c c e s a . e u

1

!

Programming a Fault Contract ◦ By default when we throw any excep>on from service, it will not reach the client side ◦ WCF provides the op>on to handle and convey the error message to client from service using SOAP Fault contract ◦ Not using Fault Contracts makes debugging and maintaining a WCF service considerably harder
