Designing and Implementation of an Inventory Control System of a Supermarket, Using Oracle, Demo and Vb (Visual Basic) A Case Study of American Shop and Supermarket

ABSTRACT An Inventory Control System defines a series of processes and actions involved in capturing raw data, processing data into useable information and disseminating information to use in the needed form. The system is a general purpose set of instruction that facilitates the process of defining, construction, controlling and manipulation of databases for various applications; this Inventory Control System describes the database as a collection of data, typically describing the activities of one or more related origination; the report covers the fundamentals of the an Inventory Control System utilizing relational database systems in coupled to Visual Basic and Demo programming. The report concentrates a lot on issues central to designing, tuning and implementation of an Inventory.
