All About The Ecosystem Of Data Science Given how quickly data science is developing, a whole ecosystem of useful tools has emerged. Since data science is so fundamentally interdisciplinary, it can be challenging to classify many of these businesses and tools. At the most fundamental level, however, they can be divided into the three components of a data scientist's workflow. Specifically, gathering, organizing, and evaluating data.
Part 1# – DATA SOURCES The remainder of this ecosystem would only exist with the data needed to operate it. Generally speaking, databases, applications, and third-party data are three very distinct types of data sources.
● Databases Unstructured databases are older than structured databases. The structured database market is estimated to be worth $25 billion, and our ecosystem includes established players like Oracle and a few upstarts like MemSQL. Structured databases, which typically run on SQL and store a set number of data columns, are utilized for business tasks like finance and operations, where accuracy and dependability are crucial considerations. Most structured databases make the fundamental premise that all queries against them must produce flawless, consistent results. Who would be an excellent example of the necessity for a structured database? The bank. Account data, personal identifiers (such as your first and last name), loans that their clients have taken out, etc., are all stored by them. Your account balance, down to the penny, must always be known to the bank. Unstructured databases are an additional option. It's hardly surprising that data scientists invented these because they approach data differently than accountants. Data scientists are more interested in flexibility than they are in exact consistency. As a result, unstructured databases make it easier to store and query large amounts of data in various ways.
● Applications Critical business data stored in the cloud has gone from unfathomable to a regular practice in the past ten years. Perhaps this is the biggest change to the business's IT infrastructure. Why is that important? Data scientists may now leverage powerful data sets from every company's division to perform predictive analysis. Although there is a lot of data, it is now dispersed among several applications. Imagine you wanted to use your SugarCRM app to view a single customer. Are you attempting to determine the number of support tickets they have created? That is most likely in the ZenDesk app. Have they checked to see if their most recent bill has been paid? It is contained in your Xero app. All of that information is spread over several locations, websites, and databases.
More data is being collected as businesses migrate to the cloud, yet it is dispersed across numerous servers and applications throughout the globe. ● The Third Party Data In comparison to unstructured databases or data applications, third-party data is significantly older. Since 1841, the core business of Dun & Bradstreet has been selling data. But over the next few years, this area will continue to change as the value of data to every firm increases. This ecosystem sector can be divided broadly into four categories: corporate information, social media data, online scrapers, and public data. ● Open Source Tool The number of open-source data stores has greatly increased, especially for unstructured data stores. Some of the most well-known ones include Cassandra, Redis, Riak, Spark, CouchDB, and MongoDB. This article primarily focuses on businesses, but Data Engineering Ecosystem, An Interactive Map, another blog post, provides a fantastic summary of the most widely used open-source data storage and extraction technologies.
Part #2 – Wrangling with Data In a recent NY Times piece, data scientist Michael Cavaretta from Ford Motors provided a wise comment. The article discussed the difficulties data scientists encounter when conducting their daily work. We truly need better tools, according to Cavaretta, so that we can spend less time organizing data and more time on the fun stuff. Predictive analysis and modeling are exciting stuff; data wrangling involves cleaning data, connecting tools, and getting data into a useful manner. You can probably guess which one is a little more fun, given that the first is occasionally referred to as a "janitor job." Since structured databases were initially created for use in operations and finance, but data scientists advocated for the advancement of unstructured databases. In this area, we see something similar taking place. For operations and financial professionals who have always worked with data, there were already a wide variety of solutions available because structured databases are an established business. However, there is also a brand-new category of tools created especially for data scientists, who face many of the same issues but frequently require more freedom. ● Enrichment Of Data Raw data is improved by data enrichment. Running predictive analysis on original data sources that are untidy, in different formats, from several apps, etc., makes it challenging, if not impossible. Data scientists don't have to clean the data because of enrichment. There are some tasks that humans are naturally better at than machines, supporting human enrichment. Consider the classification of images. If there are clouds in a satellite image, people can quickly tell. Machines still find it difficult to accomplish it consistently.
Notably, automated methods are effective for data cleansing that doesn't require a human eye. Examples range from straightforward jobs like formatting names and dates to more challenging ones like dynamically importing online metadata. G ● ETL/BLending The acronym ETL, which stands for Extract, Transform, and Load, captures the essence of what the technologies in this area of our ecosystem perform. ETL/Blending solutions for data scientists combine disparate data sources so that analysis can be performed. For further information on the ETL process, refer to the data analytics course in Mumbai.
● Integration of data Solutions for data integration and ETL/Blending software often overlap. Companies in both industries strive to integrate data, but data integration is more focused on bringing together specific formats and data applications (as opposed to working on generic sets of data).
● Api Integrators Let's now discuss API connections. These businesses emphasize integrating with as many different APIs as they can then on data transformation. I doubt many of us could have imagined how enormous this market would end up being when companies like these first began to emerge. However, these may be really potent instruments in the right hands. IFTTT is an excellent tool for understanding what happens with an API connector, to start with a fairly non-technical example. When an Instagram photo is posted, IFTTT, which stands for "if this, then that," enables the user to save it to their Dropbox or tweet about it immediately. Consider it an API connector that non-data scientists use to manage their internet reputation. But it's crucial to include it here because many data scientists I speak with utilize it as a lightweight tool for personal and professional uses.
● Opportunity Tools Open-source data wrangling tools are much less common than data storage or the analytics industry. Google released the code for their quite intriguing open-refine project. The majority of the time, businesses create their own ad hoc solutions, typically in Python; however, Kettle is an open-source ETL tool that has gained significant appeal.
Part #3 – Data Applications We've discussed how data is saved, cleaned, and integrated from several databases, and now we're there. The "fancy stuff," including predictive analysis, data mining, and machine learning, happens in data applications. This is the section where we use all this data to accomplish something extraordinary. I have broadly divided this column of our ecosystem into insights and models. While models allow you to create something from your data, insights allow you to learn something from it. They are the instruments that data scientists use to forecast the future and explain the past. ●
Insights
Data mining, cooperation, and intelligence. The first two are substantial, developed segments with, in some cases, decades-old tools. Although they are not very new, the data mining and cooperation markets are less developed. I anticipate growing significantly as more organizations increase their attention and financial support for data and data science. Again, it's challenging to establish absolutes in this situation. Many of these technologies are accessible to non-technical users, allow for the creation of dashboards, or facilitate visualization. However, they are all predicated on using data to learn something. The models' portion that follows is a little different. It's about construction. ● Models This part needs to get off to a shout-out. Shivon Zilis' excellent analysis of the machine intelligence landscape motivated this effort, and I bring it up now because modeling and machine learning have a lot in common. If you're interested in this field, her look is superb and in-depth, making reading mandatory. Models are focused on learning and prediction. In other words, either using a data set to predict what will happen or using some labeled data to train an algorithm to automatically classify more data.
● Opportunity Tools There is a sizable number of open-source modeling and insights tools, likely due to the most continuing research in this category. R serves as both a programming language and an interactive environment for data exploration, making it a crucial tool for the majority of data scientists. The open-source, free Matlab port Octave performs admirably. For technical computing, Julia is gaining popularity. There are tools in Stanford's NLP library for the majority of common language processing jobs. Most common modeling and machine learning techniques are implemented in Scikit, a robust machine learning package for Python.
