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 manyto-many relationships, in addition to one-tomanyrelationships

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 nonprofit 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.
