From our childhood, we have heard that we are nothing without water and water is our life. But in this modern technical era, the same thing can be said about data. Data means information that is basically created from a source and flows to a receiver. Every object, living or non-living is enclosed by various kinds of data. We work only with the data which we can understand and the rest of the data remains a mystery. It is impossible to work with lots of data simultaneously. This is the part where data analytics plays an important role.

**What is Data Analytics?**

Data Analytics is the process of observing, transforming, cleansing and modeling data with the goal of creating useful information and obtaining worthwhile conclusions. A data analyst is a person who is in charge of collecting and analyzing the data. The development and testing of the analytical models based on the collected and analyzed data are also done by the data analyst.

Now let’s talk about the basic requirements and the process of data analytics. First of all, the raw or unstructured data from various sources is collected and then combined into a common format. This data is then loaded into a data analytics system such as a data warehouse, a Hadoop cluster, etc. Then data cleansing and profiling are done to make sure that the data is error-free and consistent overall. After that, the main operation in data analytics is performed i.e. building an analytical model of the data using various programming languages such as SQL, Python, Scala, etc. Finally, the analytical model results are used with the help of data visualization, to make decisions and obtain the desired results.

**Career Opportunities in Data Analytics**

In this digital age, data analytics is more important than ever. There are multiple jobs opportunities in various industries with the demand for data analytics professionals increasing day by day. Some of the career opportunities that require data analytics professionals are given as follows:
