4.12 Physical Data Model

The PDM is used to design the internal schema of a database, depicting the data tables (derived from the logical data entries), the data columns of those tables (derived from the entity attributes), and the relationships between the tables (derived from the entity relationships). The features of the physical model of data include:

v Specification of all the tables and columns.

v Foreign keys are used to identify relationship between tables.

v Physical considerations may cause the physical model of data to be quite different from the logical model of data.

At this level, the data modeler will specify how the logical data model will be implemented in the database schema. The steps for physical data model design are as follows:

v Convert entities into tables.

v Convert attributes into columns.

v Modify the physical model of data based on physical constraints.

4.13 Advantage of the new system

The OOIS of La GALETTE supermarket is developed to support the existing system which presents some deficiencies. This new system will help to reduce the imperfection of clients or customers within the La GALETTE supermarket by replacing the existing system in order to benefit the advantage of information technology in better management of La GALETTE supermarket and other company of business.

CHAPTER V: IMPLEMENTATION OF THE SYSTEM

5.1 Implementation overview

The fifth chapter putting a planned system into action and examine in details the analysis and design of the online ordering and inventory system of la GALETTE supermarket. The present chapter discusses the implementation of the system, highlighting the testing exercise and describing some of the main components of the system's Graphical User Interface. It will give an output from programming language and other tools used to develop our system.

5.2 Description of tools used

The tools used in designing an online ordering and inventory system of la GALETTE supermarket are:

5.2.1 Xampp

Is a complete software package allowing using all the power and flexibility that offers the dynamic language PHP.
