Endigest AI Core Summary
Transactional databases are designed to handle large volumes of short, real-time read/write operations that ensure data accuracy, completeness and safety for business-critical activities.
•ACID properties (Atomicity, Consistency, Isolation, Durability) guarantee that every transaction is processed reliably and predictably
•Row-based storage model optimizes performance for frequent individual record insertions, updates and retrievals
•Transaction lifecycle consists of three stages: Begin, Execute operations, and Commit or Rollback to maintain data consistency
•Concurrency control using locks and isolation levels prevents dirty reads, lost updates and phantom reads in multi-user environments
•Write-ahead logging (WAL) and crash recovery mechanisms ensure data durability and integrity even after system failures
