Hello and welcome to this video.
In this video I will be introducing you to some of the key database concepts like database table relational
database relational database management systems database.
A database is a collection of organized information of data stored in a table it table stores information
in rows and columns.
Just like an Excel spreadsheet a relational database is a database with two or more related tables.
So two or more of the tables must be related.
A relational database management system also known as are DBI m.s. s for short it's software that manages
the databases so relational database management system software that manages the databases.
Examples include Oracle Microsoft secure server dbe to my school and a few others.
This is an illustration of a database.
The database is the blue cylinder.
It has two tables at the table of fruits and table core vegetables both tables have got three columns
and two rows.
I see the name on the column I mean name uncoloured.
They are afraid to ask columns.
They've both got two rows.
The rows are one and two.
So these are refers to as role.
Going this way.
So everything in record 2 is known as a roll.
So if I want to reference records from records from row number two I'll be talking about idae the name
and the collazo or these.
Here Brown Kiwi and two collectively known as is required from a roll.
So book tables.
I've also got some relationship they but have a column called Carla and the day tucked inside the kolok
column are identical.
You've got a colour green here you've got the colour green then you've got a colour brown and ikle of
brown.
So there is some relation between both tables.
So this data base can be considered a relational database because it has two tables with a relationship.
In this video we went through some of the key database concepts.
By definition we describe what a database is is a collection of organize information of data stored
in a table.
