Lec-3 Integrity Constraints Complete Details with Examples | integrity constraints in dbms

Hey There Dev Champ…This is the 3rd time we are sitting together to discuss Relational Database Management System…

Previously we discussed Types of Keys in a Database Management System. If you have missed it out, watch the video by clicking on the link above. Link is also available in the description below.

Questions answered in this video:
1) What are Integrity Constraints (Entity Integrity Constraints) in Database Management System (dbms) ?
2) Why do we need Integrity Constraints in Database Management System (dbms) ?
3) What are the different Types of Integrity Constraints in DBMS?
4) What is Not Null Constraint?
5) What is Unique Constraint ?
6) What is Primary Key Constraint ?
7) What is Referential Integrity Constraint or Foreign Key Constraint ?
8) What is Default Constraint ?
9) What is Domain Constraint or Check Constraint ?

Integrity Constraints refer to the fact, that data remains consistent and complete after any insertion, deletion or updation of data in the table,
And all this is required to maintain the quality and accuracy of data in database. To ensure this, we need to apply different constraints on the columns of a table.
All these constraints are generally known as Integrity Constraints.

In this video you can find complete details regarding concept of different integrity constraints in DBMS. In our SQL series, we shall once again discuss these constraints and learn how to apply these constraints on a table in Database using SQL language.
If you have any questions, please post them in comments below and we shall try to answer them as quickly as possible…
Stay Connected and follow the series as we dig deeper and discuss
Different ways to join the tables together through joins in dbms, in next lecture.

If you liked the video, care subscribing the channel so that you can follow the upcoming videos and share it with your colleagues which you think can use the help we are trying to provide here.
Cheers !

Lec- 1: Database Types | Relational vs Non Relational databases | Types of Database

Hey There Dev Champ, this is the start of series on Database Management System.
The motivation behind this series is to clear or refresh all of your concepts regarding Database Management Systems, theoretically as well as practically.

Questions Answered:
1) What is a Database Management System?
2) What is it used for?
3) What are the Types of Database Management System?
4) When and Why to use Relational or Non-relational Database Management System?
5) Difference between dbms and rdbms ?
6) what is rdbms ?

Database management is the process of collecting, storing, organizing, maintaining and analyzing data.

There are 2 types of Databases
First one is Relational Database Management Systems or RDBMS.
Then there comes the 2nd type of DBMS, Non-Relational Databases or NRDBMS
The non-relational database, No SQL database, stores data just like RDBMS. However, unlike the relational databases, there are no tables, rows, columns or keys.

Detailed comparison between Relational and Non-Relational Database Management Systems, database types, Using animated doodles, illustrations and engaging figures, is in this video.
