In this video, SQL Server instructor Peter Avila presents a simple explanation to what a database is and how to use them.

There are a few terms for SQL Server administrators to understand as they pertain to databases.


An aspect of the real world. Anything from which a database can be made from.


The raw facts such as transaction details that describe the relevant aspects of the miniworld, including its entities, relationships, states and others.


We store all these facts so that we can ask the database questions against the data. Information is derived from the data and supports the decision-making process.

Once these terms are understood, then we can establish a database.


A repository of data that acts as a model of a miniworls in which data are organized in a way that makes it possible to retrieve useful information.
