Data analysts collect, process and perform statistical analyses of data. Their skills may not be as advanced as data scientists (e.g. they may not be able to create new algorithms), but their goals are the same – to discover how data can be used to answer questions and solve problems.
What is a Data Analyst?
Analyzing data begins with its roots in statistics which, itself, stems into a long history into the period of pyramid building in Egypt. In some other later, but still early forms, data analysis can be seen in censuses, taxing, and other governmental roles across the world.
With the development of computers and an ever increasing move toward technological intertwinement, data analysis began to evolve. Early data analysts use tabulating machines to count data from punch cards. In 1980, the development of the relational database gave new breath to data analysts, which allowed them to use Sequel (SQL) to retrieve data from databases.
