As a QA engineer, learning SQL is a must. After all, understanding databases and writing SQL queries is essential for testing the functionality and performance of any enterprise application. For DBAs, SQL skills are even more critical as they’re responsible for creating database schemas, tuning DB entities, and ensuring the system’s overall performance.
But the importance of SQL doesn’t stop there. In today’s digital landscape, areas like Big Data, Cloud Computing, and Data Analytics are expanding the role of SQL and database programming. That’s why interviewers are always keen to assess a candidate’s SQL knowledge. And with good reason! Knowing SQL can give you a competitive edge in the job market and help you advance your career.
Why should I learn SQL and database programming?
A database, commonly known as the backend, is critical for any Enterprise Application. So it has to be regressed for functionality and performance. To access or manage a database, we need a Structured Query Language (SQL). It is a database programming language that gives us the means to work with different types of databases like Oracle, SQL Server, MYSQL, MongoDB, etc.
There are ample reasons that confirm the significance of SQL for Software testers and DBA professionals. DBA has to prepare database schemas and create tables and indexes. Also, he needs to tune the DB entities to step up the performance. On the other hand, a tester’s responsibilities are as follows.
- Write SQL queries to validate the integrity of the DB.
- Generate virtual load on the server.
- Testing – Upgrade of SQL software version.
- Testing – DB migration from an older DB to a newer version.
However, there are many emerging areas such as Big Data, Cloud Computing, and Data Analytics that extend the scope of SQL and database programming. Hence, it’s a favorite subject for the interviewers which eventually makes it a mandatory skill for the candidates.
SQL is so interoperable that it fetches the attention of QA engineers and interviewers to add it as one of the key criteria for selection. It is also a fact that SQL/Database is an essential part of any computer science-related academic or degree program. So most engineers already have a basic understanding of SQL concepts.
