How does data analytics function?

Understanding data analytics

The companies collect data sets in bulk day in and day out. Data analytics is just the way of examining these with the intention of drawing out some inferences regarding the inner information they usually contain which is not obvious in the first glance. This is mostly done by using special software and systems meant for this purpose.

Where is it used?

All industries use this technology. It is however, far often used in commercial spaces so that enterprises can make better and informed decisions when it comes to business. The utility of data analytics is vast because it has the capacity to aid increasing revenues, make marketing efforts more fruitful, assist companies to outdo their competition and optimize efficient operations.

What kind of data is captured and analyzed?

Data could either be historical in nature which shows the past instances of how things were done and perceived or it can dish out new information altogether using real-time analysis. This points towards the current ongoing behavior and specifics regarding customers. Data can be derived both internally and through external sources.

The function itself

Analyzing data is not the only task of data analytics applications. If there are advanced projects at hand, a lot of steps take place in this area. There is collection, integration and preparation of data that is further developed and tested. Revised analytical models are also depended on in order to obtain results that are high in accuracy. Data's engineers are usually the ones who take up the task of getting data sets ready in order to be analyzed.

The process in steps

·       The process of data analytics firstly begins with the process of data collection itself.

·       The information required for a specific analytics application is first identified by designated data scientists.

·       Integration routines are used to combine the data that is collected (usually from various source systems) and said data has to be converted into a common format in order to be uploaded into the analytics system.

·       Problems in data qualities that might affect accuracy in these applications, then need to be rectified through procedures known as data cleansing and profiling. This is to ensure that the information that is later derived is free of errors and is consistent. Entries cannot be duplicated either, that would be an issue.

·       Data needs to be handled with care, and for that reason there is a strict watch kept on data governance policies.

·       An analytical model is built by the data scientist assigned for the job using any relevant data analytics software such as prescriptive or predictive modelling.

·       Programming languages like R, Python, SQL etc are used for this purpose. The analyst must be well-versed in them.

·       A partial data set will be used as a test-run to check the accuracy of the prepared model. It is subjected to a revised testing as well just to be sure.

·       Ultimately, the whole data set is exposed to the model and the information retrieved will be constantly updated and is of great use to the organization.

As technology and automating occurs more rapidly in the future, the need for data scientists to meet business requirements will be very high. Skills pertaining to deep learning, creating models, gathering insights, etc. will be of high value, especially for organizations looking for specific answers. Data analytics courses in Pune can help in acquiring these skills.
