What is a Database by SQL Server instructor Peter Avila
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.
Miniworld:
An aspect of the real world. Anything from which a database can be made from.
Data:
The raw facts such as transaction details that describe the relevant aspects of the miniworld, including its entities, relationships, states and others.
Information:
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.
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.
