What are Databases?

In computing, a database can be defined as a structured collection of records or data that is stored in a computer so that a program can consult it to answer queries.

Different Database Models

• Hierarchical Model The hierarchical database model is an

inverted tree-like structure. The tables of this model take on a child-parent relationship. Each child table has a single parent table, and each parent table can have multiple child tables.

Different Database Models

• Network Model The network database model is essentially a

refinement of the hierarchical database model. The network model allows child tables to have more than one parent, thus creating a networked-like table structure. Multiple parent tables for each child allows for many-to-many relationships, in addition to one-to-manyrelationships

Different Database Models

• Relational Model The relational database model improves on

the restriction of a hierarchical structure, not completely abandoning the hierarchy of data, as shown in. Any table can be accessed directly without having to access all parent objects

What is a Commercial Database?

A Commercial Database is used by a commercial Company to store and query data. This data can be customer’s, Employees, Stock details and any other data the company needs to store in their operations.The Commercial Company is created with profit in mind and uses the database for its commercial values. Theses types of databases can have a small amount of involvement in the company’s operations or the company can fully rely on the database’s functionality for its operations.

What is a Non-Commercial Environments ?

This policy, mainly extracted from law of Great Britain and Canada, addresses the conditions that an entity must meet to qualify as a non-profit organization for purposes of the non-commercial licensing. When determining whether an entity is a non-profit organisation, the entity must meet all of the following conditions: •It was organised solely for non-profit purposes. •It is in fact operated solely for non-profit purposes. •It does not distribute or otherwise make available for the personal benefit of any member any of its income.
