SQL facilitates communication with the database, especially relational database and it is the standard language for relational database management systems. It is used to perform tasks that include data from a database or retrieve data from a database.
The SQL test measures individuals’ ability and proficiency in working with different SQL servers. It also judges their understanding of several SQL components like tables, queries, subqueries, and database server components. These individuals will assist your organization in handling and managing SQL servers and help in data migration using tables, queries, and subqueries of relational database management systems.
Testlify’s skill tests are designed by experienced SMEs (subject matter experts). We evaluate these experts based on specific metrics such as expertise, capability, and their market reputation. Prior to being published, each skill test is peer-reviewed by other experts and then calibrated based on insights derived from a significant number of test-takers who are well-versed in that skill area. Our inherent feedback systems and built-in algorithms enable our SMEs to refine our tests continually.
