be developed by end users with little or no formal assistance from technical specialists. Users

ii) Electronic data interchange
EDI is an electronic means for transmitting business transactions between organizations. The
transmissions use standard formats such as specific record types and field definitions.
The EDI process is a hybrid process of systems software and application systems. EDI system
software can provide utility services used by all application systems. These services include
transmission, translation and storage of transactions initialized by or destined for application
processing. EDI is an application system in that the functions it performs are based on business
needs- and activities. The applications, transactions and trading partners supported will change
over time and the co-mingling of transactions, purchase orders, shipping notices, invoices and
payments in the EDI process makes it necessary to include application processing procedures
and controls in the EDI process.
iii) Data warehouse
A data warehouse is a subject-oriented, integrated, time-variant, non-volatile collection of data in
support of management's decision-making process. It may also be defined as a database with
reporting and query tools, that store current and historical data extracted from various operational
systems and consolidated for management reporting and analysis.
iv. Information center
Information Resource Centers co-ordinate all information activities within their areas of interest
and expertise. Information within that area is analysed, abstracted arid indexed for effective
storage, retrieval and dissemination.
