As we all know that SQL stand for sequence query language. it is a unique language use for control or manipulate data in DB. And DBMS is a software. So they both are noting without each other. There is a relationship of compiler and language in between them.

Dbms and rdbms?
A DBMS (Database Management System) is a software application that allows users to interact with a database. An RDBMS (Relational Database Management System) is a type of DBMS that organizes data into tables with rows and columns, and uses structured query language (SQL) for querying and managing data. RDBMSs are a subset of DBMSs, designed specifically for relational databases.
Major difference between dbms vs rdbms?
A DBMS (Database Management System) is a software that manages databases and provides functionalities to store, retrieve, and update data. An RDBMS (Relational Database Management System) is a type of DBMS that stores data in a structured way using tables with relationships between them. RDBMS enforces the relational model, which allows for data integrity through constraints and supports SQL for querying data.
What is the difference between a procedural and a non-procedural language IN DBMS?
In a procedural language, like PL/SQL, the programmer specifies the steps to be taken to accomplish a task, while in a non-procedural language, like SQL, the programmer specifies what needs to be done rather than how to do it. In the context of a DBMS, procedural languages are used for developing complex logic and operations within the database, while non-procedural languages are used for querying and manipulating data.
How the user requests for the required data is handled by DBMS explain with the help of example?
In a DBMS, the user requests for data by submitting queries written in a structured query language (SQL). These queries are then processed by the DBMS to locate and retrieve the requested data from the database tables. For example, a user can request all records of employees who work in a specific department by writing a SQL query that specifies the department's name and selects the relevant data fields. The DBMS then executes this query, retrieves the matching data from the database, and presents it to the user.
What are the names of dbms tools?
Some popular database management system (DBMS) tools include MySQL, Microsoft SQL Server, Oracle Database, and PostgreSQL. These tools are widely used for storing, managing, and retrieving data in various applications and systems.

yes
What are the differences between a sql server dba and a sql dba?
The term SQL alone implies Structured Query Language as per the ANSI standard. Every Database Management System (DBMS) has its own "software" that makes it work. That being said, the term "SQL DBA" alone does not make any sense without mentioning the vendor specific DBMS you are managing. So, an SQL Server DBA is an administrator of Microsoft's SQL Server.
What are dbms languages?
DBMS languages are specialized programming languages used to interact with databases. Common DBMS languages include SQL (Structured Query Language) for querying and manipulating data, and PL/SQL (Procedural Language/SQL) for developing procedures and functions within a database system. These languages are designed to facilitate communication with the database management system and perform various operations on the data stored in the database.
What is dynamic sql in dbms?
Although static SQL works well in many situations, there is a class of applications in which the data access cannot be determined in advance. For example, suppose a spreadsheet allows a user to enter a query, which the spreadsheet then sends to the DBMS to retrieve data. The contents of this query obviously cannot be known to the programmer when the spreadsheet program is written. To solve this problem, the spreadsheet uses a form of embedded SQL called dynamic SQL. Unlike static SQL statements, which are hard-coded in the program, dynamic SQL statements can be built at run time and placed in a string host variable. They are then sent to the DBMS for processing. Because the DBMS must generate an access plan at run time for dynamic SQL statements, dynamic SQL is generally slower than static SQL. When a program containing dynamic SQL statements is compiled, the dynamic SQL statements are not stripped from the program, as in static SQL. Instead, they are replaced by a function call that passes the statement to the DBMS; static SQL statements in the same program are treated normally.
Sample of DBMS?
