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. Hierarchical Model The hierarchical database model is an inverted tree-like structure.

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 Network Model The network database model is essentially a refinement of the hierarchical database model.

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 Relational Model The relational database model improves on the restriction of a hierarchical structure, not completely abandoning the hierarchy of data, as shown in.

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.

Databases Overview 8/24/2015 As discussed in this presentation, the database is a very important tool to all types of organisations. The database helps each type of organize their required data for their individual operational requirement. Database management system has become an important tool to the commercial environment, because of the requirements of the commercial company’s operations, and has become a valuable tool in today’s commercial market.
