SQL is Structured Query Language. SQL is basically a database language primarily designed for managing and manipulating data in DBMS or RDBMS.
DBMS is Database Management System and RDBMS is Relational Database Management System. DBMS and RDBMS both are the procedures to store data in the form of columns and rows. The main difference between both is that in Relational Database Management System we can make a relationship between the tables.

Exchange Server Information Store databases support transaction logging i.e. before committing any data to the database, it is first written to transaction logs. If your database is ever forced to perform recovery, these transaction logs replay and restore the database to a working state. When an Exchange Server Information Store database corrupts, it marks an event indicating the root cause of the issue. You can deduce the problem and thus, take corrective measures to solve it. In cases, when no backup is available to replace the damaged database and ESEUTIL utility also fails to repair, you need to use an effective Microsoft utility that could repair and restore the damaged database.
