DBMS (Database Management System)is software for storing and retrieving users’ data while also considering appropriate security measures. The system is composed of a number of programs that manipulate the Database. It accepts the request for data from an application and instructs the operating system to provide the specific data.
RDBMS is a short form of Relational Database Management system. It is a software system that stores only data that needs to be stored in related tables. In RDBMS, data is managed and stored in rows and columns, known as tuples and attributes.
Here are advances in using a DBMS system: 1. DBMS offers various techniques and powerful functions to efficiently store & retrieve data. 2. It is an efficient handler to balance the needs of multiple applications using the same data. 3. Provides Uniform administration procedures for data management. 4. Application programs that are never exposed to...
Livelock is a situation in which an exclusive lock request is repeatedly denied as many overlapping shared locks keep interfering with each other. The processes keep changing their status, preventi...
Division of a logical database into complete independent units for improving its management, availability, and performance is called Database partitioning.
A Deadlockis a situation that occurs in OS when any process enters a waiting state as another waiting process is holding the demanded resource. It is a common problem in multi-processing where several processes share a specific type of mutually exclusive resource known as a soft lock. Example of Deadlock: A real-world example should be traffic, whi...
Relational Algebra is a procedural query language that collects relations as input and gives occurrences of relations as output. It uses various operations to perform this action.
In relational algebra, PROJECTION and SELECTION are unary operations. Unary operations are those kinds of operations that use only single operands. As in SELECTION, relational operators are used, for example – =, <=,>=, etc.
Concurrency Controlis a procedure that helps to manage simultaneous operations without conflicting with each other. It helps you to ensure that Database transactions are executed concurrently and accurately.
Here are three types of languages used in DBMS: 1. DDL: Data Definition Language, which defines the database and schema structure using CREATE, ALTER, DROP, and RENAME. 2. DCL: DCL is a Data Control Language used to control the users’ access inside the Database using some SQL Queries like REVOKW and GRANT. 3. DML: Data Manipulation Language, which ...
