MySQL

MySQL is the most popular open source database system.

MySQL

MySQL is a relational database management system that runs as a server providing multi-user access to a number of databases.

The data in MySQL is stored in database objects called tables.

A table is a collection of related data entries and consists of rows and columns.

Databases are useful when storing information categorically.

Database Tables

A database most often contains one or more tables.

Each table is identified by a name (e.g. "Customers" or "Orders").

Tables contain records (rows) with data.

Below is an example of a table called "Persons":

Persons Table:Last Name

FirstName

Address City

Handsen Ola Timoteivn 10

Sandnes

Joy Tova Borgvn 23 Sandnes

San Karim Storgt 20 Stavanger

Queries

*A query is a question or a request. * With MySQL, we can query a database for specific information and

have a recordset returned.

Example : Select LastName from persons

This query selects all the data in "LastName" column from "Persons" table, and will return a recordset like this:

LastName
