Question

What is an RDBMS? Name some examples for RDBMS? What is CRUD?

Answer 1

• A relational database management system (RDBMS) is a database management system that is based on a relational model. The relational model uses the basic concept of a relation or table. RDBMS is the basis for SQL, and for database systems like MS SQL Server, IBM DB2, Oracle, MySQL, and Microsoft Access.
• In computer programming, create, read, update and delete[1] (as an acronym CRUD or possibly a backronym) (Sometimes called SCRUD with an “S” for Search) are the four basic functions of persistent storage.

Answer 2

RDBMS: Relational Database Management System

A relational database management system (RDBMS) is a collection of programs and capabilities that enable IT teams and others to create, update, administer and otherwise interact with a relational database. Most commercial RDBMSes use Structured Query Language (SQL) to access the database, although SQL was invented after the initial development of the relational model and is not necessary for its use.

Example: MySQL, Oracle Database, PostgreSQL etc

CRUD: Create, Read, Update & Delete

The CRUD cycle describes the elemental functions of a persistent database. CRUD stands for Create, Read, Update and Delete. (Retrieve may occasionally be substituted for Read.) These functions are also descriptive of the data life cycle.
