A Database Management system (DBMS) is a software specially designed to manage the database by defining, retrieving, and manipulating its data. DBMS manages data depending on the application requirements.  SQL or Structured Query Language is a programming language using which a database can be accessed. The function of the SQL tools is to manipulate the data in a database while on the other hand DBMS is associated with the management of data in the same database. It is impossible to construct any computer application without a proper database; therefore, it is extremely important for a developer to have a clear and basic understanding of the database and all other associates. All those who aspire to pursue a successful career as a system and software developer must know the difference between DBMS and SQL tools.

Four types of DBMS are there- 

hierarchical DBMS, Relational DBMS, Object-Oriented Relation DBMS, and Network DBMS. Structured Query Language (SQL) is typically applicable for the Relational Database system. Several SQL tools are there to perform various types of operations like manipulation, maintenance, and optimization. 

DBMS software is most popular - MySQL, Oracle, MS SQL Server.

Popular management tools on SQL are - Navicat Monitor, Adminer, DBComparer and many more. 

SQL learning is relatively easy and flat with limited functionalities typically used for some specific purposes. Anyone who learns it once can use the same SQL in all DBMS software with little changes and modifications in some of the other. On the other hand, DBMS software is relatively difficult to learn and therefore, one has to put a lot of effort and invest time in becoming a master in the domain.
