Transaction Processing System (TPS) – Components, Attributes
What is Transaction Processing System?
TPS is an information system that is used to process day to day transactions such as purchases, expenses, sales, receipts, payments, etc. TPS may provide us with meaningful routine reports such as profit & loss a/c and balance sheet, etc.

A TPS may be defined as an Information system that collects, stores, retrieves day to day transactions of the organization. TPS generally may be used in Railway Reservation Systems, Accounting Systems, Banking Systems, etc. Global economy is a major reason for the advancement of TPS.
Qualifiers For TPS
- Atomicity: A transaction must be completed in full and not in parts. A transaction must take place in entirety.
- Consistency: Data integrity or consistency should be well maintained. Cash should not go negative in the books, this is a requirement of the management so the system should be such that it does not accepts any cash payment related transaction when the cash is not available.
- Isolation: The transactions must be executed simultaneously but individual privacy should not be disturbed. Debit and credit should occur simultaneously without affecting each other.

Attributes of TPS:
- ACCESS CONTROL: TPS generally has features by which only authorized users are allowed to access the system. Thus, any unauthorized user cannot make changes to the system or access the system. This access control feature leads to security of the TPS.
- EQUIVALENCE: TPS provide similar format to its users for data entry thus users efficiency gets increased and the overall system effectiveness is also improved.
- HIGH VOLOUME RAPID PROCESSING: A pre requirement is that TPS must be able to process huge transactions within very less time and that too efficiently. We know the number of transactions occurring in railway system and the quickness required. A TPS must be such that it may handle large number of transactions without any failure.

Components of TPS:
- Inputs: Source documents such as Customer orders, invoices, purchase orders, etc. serves as Inputs to the TPS system.
- Processing: Once the inputs are provided, they are further processed to get an output.
- Storage: Ledgers serves as a source of storage.
