Study Notes
Transaction Processing Systems (TPSs)
- TPSs capture and process the detailed data necessary to update records about the fundamental business operations of an organization.
- Examples of TPSs include order entry, inventory control, payroll, attendance systems, reservation systems, point of sale, etc.
- Input to TPSs include customer orders, credit cards, purchase orders, etc.
Data Manipulation
- Performing calculations and other data transformations related to business transactions.
- Includes: classifying data, sorting data into categories, performing calculations, summarizing results, and storing data in the organization's database for further processing.
Data Storage
- Updating one or more databases with new transactions.
- Data can be further processed and manipulated by other systems after being updated.
Document Production and Reports
- Generating output records, documents, and reports, including hard-copy paper reports and displays on computer screens.
- Results from one TPS can be inputs to another system.
Transaction Processing Activities
- Capture and process data that describes fundamental business transactions.
- Update databases.
- Produce a variety of reports.
Transaction Processing Cycle
- The process of data collection, data editing, data correction, data manipulation, data storage, and document production.
Data Collection
- Capturing and gathering all data necessary to complete the processing of transactions.
- Data collection can be manual or automated via special input devices.
- Data should be collected at source and recorded accurately and in a timely fashion.
Data Editing
- Checking data for validity and completeness to detect any problems.
- Examples: quantity and cost data must be numeric, names must be alphabetic.
Data Correction
- Reentering data that was not typed or scanned properly.
- Error messages must specify the problem so proper corrections can be made.
