While you know how it really works is a more advanced ability, it is important to understand what they are and what they do and what they do to effectively surf the data in their database.

5. Queries

Queries are like the joints, they are used to connect the data between the different tables, but when they are executed correctly, they are faster and faster than one to eliminate additional data steps in data extraction. 

Learn when and where you can use substrates instead of joints and learn to write readable SQLS, and stay using the common expressions of the table, even when your sub-parents become more complex.  

6. Working of indexes

For the faster run, database indexes make queries faster. Impose the order in the data tables; this facilitates queries to discuss the desired information. Since the indexes are created and the different types will give you more understanding of how to use them effectively.

 9. Plan Execution

The execution plans are a visual representation of how a database engine performs a query. Basically, they allow you to look under the hood and see how the information is created. 

The execution plans can help you a lot about the efficiency of a query and the main tool to solve the problems of a slow or lower query. Reading and understanding them can help you adjust queries without ruining performance. Find out how to pull an execution plan, read one and tune to increase the performance of the query. 

10. Backup of databases 

Database backup creation is important in case of critical damage. There are different types of backup copies, and know what use and how to configure (and restore) each is an important part of the database administration.
