Hey There Dev Champ…This video is a short video of complete details on Integrity Constraints in dbms. You can access the full video from the link above or in the description below:

Questions answered in this video:
1) what is the difference between a primary key and a unique key?
2) What is a primary key constraint?
3) What are the examples of primary key constraint?
4) What is a unique key constraint?
5) What are the examples of unqiue key constraint?
6) what is the difference between a primary key and a unique key 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.

If you have any questions, please post them in comments below and we shall try to answer them as quickly as possible…

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 !

Difference between Primary and Foreign Key in DBMS | Primary key and Foreign key in SQL

Hey There Dev Champ, We have gathered here once again to discuss Relational Database Management System…

In this video we shall discuss the Difference between Primary Key and Foreign Key in DBMS & Primary key and Foreign key in SQL.

This video is a short video of complete discussion on Keys in DBMS. If you have missed it out, watch the video by clicking on the link above. Link is also available in the description below.

A Primary Key can consist of a single or multiple columns of a table to uniquely identify a row of the table
and it cannot contain Null or duplicate value.

Foreign Key, As the name specifies, it is a key which is used to combine different tables together based on value of some column.

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.

Lec- 2: Types of Keys in DBMS | Tables in DBMS | Keys in DBMS

Hey There Dev Champ, This is the 2nd time we are sitting together to discuss Relational Database Management System

Previously we compared the Relational Database Management System and Non-Relational Database Management System.

In this video, Question answered:
What is a Table in Relational Database Management System?
What is a Key in RDBMS?
what are the different types of keys in RDBMS and when are they used?
Question answered:
what is tuple in dbms ?
Difference between primary key and candidate key ?
what is candidate key in dbms ?
concept of keys in dbms
Using animated doodles, illustrations and engaging figures.

Row is also known as "Tuple" …
where the term "attribute" is used for a column …
and a table is also called "Relation"…

In a relational database keys are used to create a connection between different relations i.e. tables.

There are multiple Types of Keys, such as
Super Key in dbms
Primary Key in dbms
Candidate Key in dbms
Alternate Key or Secondary Key in dbms
Foreign Key in dbms
Composite Key in dbms
Compound Key in dbms
And Surrogate key in dbms

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.

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 !
