Abstract:
The paper presents the increase in the development of business applications by modularizing operational functions in information systems. Operational information systems process data generated and used in business operations. Depending on the role they play, there are several categories: transaction processing systems - record and process data resulting from transactions, update databases and produce a variety of documents and reports; process control systems - provide operational decisions that control physical processes; automated service systems - those that support communications. Information systems have always been necessary for processing data generated and used in business operations. Operational IS produce a variety of information, but they (the information) do not highlight which information products are most suitable for managers. For this reason, further processing through information systems is necessary. Operational information systems include most transaction processing systems, which have evolved from manual IS to mechanical data processing systems and then to electronic data processing systems. Transaction processing systems record and process data resulting from transactions such as sales, purchases, and inventory changes. They can process data created by changes to items in a database file like changes in a customer’s name and address, generating a variety of information products for internal or external use such as customer invoices, paychecks, sales receipts, purchase orders, dividend payments, tax payments, and financial statements), and documenting the databases used by an organization for further processing through management information systems. Operational information systems play an important role within companies by storing data related to production activities and using it later for managers' decision-making processes.
