Client

Requirement

The TrackPad works in any offline environment! All data is saved regardless of connection status making it great for areas such as parking lots or areas where there is no Wi-Fi or data. The purpose is to enhance the already build iPad app which was utilized for IOS Mobile Based Incident Management System with the following features: 

Automated syncing with server



Customization in long form



Data merging through iPad app



Minor Touch-ups

Project

Challenges

Team faced the following challenges: 

Developing an application in iPad platform.



Developing automated syncing with the server. Syncing data with server and app and vice-versa in every 20 seconds.



Customization of Long form as per the requirement and also implemented Minor Touch-ups and Data merging functionality.

Planning Keeping in mind the enormous structure of the application and the challenges involved a four-tier development approach was considered consisting of:  The Database layer containing SQLite Mobile Database and MYSQL Database.  The Interface layer and Database Abstraction layer for converting data between incompatible type systems in databases and accessing data from the database respectively.  The Business Logic layer consisting of all the business logic procedures for varied modules.  The User Interface layer which forms the Graphical User Interface of the iPad application.

Architecture The ISS Trackpad is built around Objective-C. Modules were developed in Objective-C such that they can be executed directly from the UI layer. These Objective-C files consisted of all the business logics used for respective modules like Save (Add/Update), Delete, Get Single Object, Get Multiple Objects for Listing and were designed to be capable of handling many more logics which were not related to the database.

In order to most effectively access the database in an object-oriented context, an interface translating the object logic to the relational logic was used to communicate with the relational databases in an object-oriented manner. An intermediary abstraction layer was created for accessing data from the database. The UI layer was kept free of any business logic with images, applications and data being called from their respective servers.

Highlights

The application was equipped with a robust architecture to access Incidences. Incidences will be automatically synced with server in the application. With this all web and iPad app Incidences will be same at both the ends and all updated web acknowledged Incidences will be showcased onto the iPad app.

The sync process will be running as background thread after a certain time interval and at start of the application. Custom fields in the Long form will be updated as customized in the Web CMS form. The form will be generated from the parsed web services having custom form fields as attributes.
