Constructive Review of Transaction Models in Database Systems
Main Article Content
Abstract
Transaction processing provides mechanisms that can solve many of the problems incurred by concurrent access to shared objects in large
databases. The use of transactions to provide reliable and secure information processing and data management has increasingly gained the attention
of advanced database applications. Transactions adhering to the ACID properties are guaranteed to be atomic and serializable that is suitable for
database applications characterized by short duration transactions and competitive access to shared data. The emergence of advanced applications
characterized by long duration with cooperative transactions requires the need for advanced transaction models. Advanced transaction models focus
on maintaining data consistency and have provided solutions to many problems such as correctness, consistency and reliability in transaction
processing and database management environments. This research paper reviews the various transaction models proposed in the literature that had a
considerable impact on the field of transaction processing in database systems. Also this paper identifies that an Event-Condition-Action (ECA) rule
paradigm has been a flexible mechanism for supporting the requirements of advanced applications.
