Operations Support System

The operations support system provides information about the day-to-day activities of the organization. They support the operations of the organization, by keeping track of the resources and the transactions. For example, in a banking operation, the operations support system are used to keep track of current balance of the customer; in a manufacturing unit, it helps to keep track of the inventory of the items; and, in a sales unit, it keeps track of the number of units of each item sold. Thus, transaction processing is the main function of the operations support system.
An operational support system (OSS) is a group of computer programs or an IT system used by communications service providers for monitoring, controlling, analyzing and managing a computer or telephone network system. OSS software is specifically dedicated to telecommunications service providers and mainly used for supporting network processes to maintain network inventory, configure network components, provision services and manage faults.
Operations support systems (also called operational support systems or OSS) are computer systems used by telecommunications service providers. The term OSS most frequently describes "network systems" dealing with the telecom network itself, supporting processes such as maintaining network inventory, provisioning services, configuring network components, and managing faults. The complementary term, business support systems or BSS, is a newer term and typically refers to “business systems” dealing with customers, supporting processes such as taking orders, processing bills, and collecting payments. The two systems together are often abbreviated OSS/BSS, BSS/OSS or simply B/OSS.

Subset of management information system (MIS), it extends the information retrieval capabilities of the end-users with 'query and analysis functions' for searching a database, generating 'what if' scenarios, and other such purposes.
