Introduction to Serializability in DBMS Transactions in a database correspond to the set of instructions that are executed to achieve a target. All the transactions that take place in a database by theory should satisfy the ACID property. ACID is the acronym used to define transaction properties ...
In write-write conflicts, two transactions write to the same data item. To avoid inconsistency, one of the transactions must be aborted or rolled back. Conflict serializability is used in most commercial DBMS, as it provides a simple and efficient method of ensuring serializability. ...
A database management system (DBMS) is modified to provide improved concurrent usage of database objects, particularly when the system is executing long lived transactions. A subset of the transactions access database objects using parameterized read and parameterized write access modes. Each ...
We know that a serial schedule never leaves the database in inconsistent state because there are no concurrent transactions execution. However a non-serial schedule can leave the database in inconsistent state because there are multiple transactions running concurrently. By checking that a given non-...

To achieve a high degree of concurrency, transactions are scheduled at the ILGS module, regardless of they are local or global, in a way that unnecessary abort or delay is not caused. By simply adding the ILGS level on top of each local DBMS, local DBMSs need not be changed at all....
Most of the prior work on multidatabase transaction management =-=[5, 6, 18, 19, 22, 27, 31]-=- has focussed on ways to integrate the transaction processing algorithms of disparate DBMSs to achieve some correctness criteria such as global serializability [3], or an approximation of it ...
