Scheduling Nested Transactions in Real-Time Database Systemsed transactions. Timeliness is the key issue in scheduling transactions in a RT-DBMS. For a RTDBMS where transactions have firm deadlines, transactions are useless once they expire their deadlines and, therefore, are aborted and their work is undone (rolled back) once they reach their deadlines befo哀求 发表于 2025-3-28 20:46:14

Concurrency Control for Approximate Query Processing of Real-Time Database Systemsossible for real-time database systems to meet deadlines. A network partition or a host failure can cause some needed data to become inaccessible. Similarly, database transactions in a real-time system can share data, and while con-currency control is needed to ensure data integrity, concurrency conesthetician 发表于 2025-3-29 23:09:49
