ETL Process

ETL stands for extract, transform, and load. It is a data integration process in which the programmers syndicate all the data into one place.

Aggregate the Data

Data collected from various sources is consolidated. Finally, it is simplified with statistics and charts and summarized for future reference.

Data Cleaning

The cleaning process begins once we have all the data in one place. Data must be structured, standardized, and cleaned up to be valid. It is known as data cleaning. For example, the data analyst ensures that all dates are consistent and follow the correct sequence order so that they may be optimized and evaluated.

Data Visualization and Report Development

Data analysts produce visual representations of data such as graphs, pie charts, and maps. It is turned into charts and reports to understand the raw data better. For example, suppose a food delivery client wants to know which location orders the most biryani. In that case, the data analyst will offer a visual indicating which area receives the most biryani orders.

Create Reports and Visualization

The data analyst will develop a report based on the client’s objectives and needs. Depending on the client’s needs, it could be daily, weekly, or monthly. Next, the data analyst will use SQL (Structured Query Language) to automate the reports and connect the data to a data visualization platform. At this step, the data analyst will also ensure that the client’s initial questions and problems are resolved.

What is the Qualification Required to Become a Data Analyst?
