Let’s Talk SQL
SQL stands for Structured Query Language. It is actually a programming language that we use for querying databases. Different RDBMS (relational database management systems) support different specifications, but the main query structure, keywords, and operators would be the same among all SQL software.
I use SQL on a daily basis but it does not mean you will do. So, do you actually need to know SQL? When I thought about this I made the following two-part conclusion:
Firstly, the most valuable thing about SQL knowledge is that it helps to construct formal sentences. These sentences help to describe the algorithm we need to implement to access business data.
Secondly, while there are many types of business data that are actually way far from structured data and can’t be queried with SQL (such as music, photos, data from hardware sensors, etc.), each company still must have an accounting system. This system would probably be SQL-based and would not only serve for government reporting and taxation. It could provide data that helps understand how the business is going.
