Logical Database Design
At Technousa we first understand the requirements of the users. Why do they want a database? What is it supposed to achieve? What real-world process is it designed to emulate?
We talk to the users and construct a model of the database they want, without adding any of the technical stuff. This model is called the logical model because it is a logical description of what we are going to build. The logical design process lets you create efficient databases so that your applications will perform smoothly and is easy to maintain and support.

The process consists of several distinct steps : |
- Identifying the data for tables
- Normalizing the data
- Arranging data in tables
- Designing views
- Designing indexes
- Designing hash structures
- Designing integrity constraints
- Defining security levels
