Generic application architectures help categorize systems into common types including data processing systems, transaction processing systems, event processing systems, and language processing systems. Data processing systems operate in batches to process input data and output results without user intervention. Transaction processing systems allow multiple users to access and update a shared database. Event processing systems like editors must rapidly respond to unpredictable user events by modifying an in-store data structure. Language processing systems translate or interpret a specified language into another representation.
