Data Consistency of Distributed Transaction for Order Management

The client/server method of networkcommunications is the most popular one. Its easeof implementation and scalability make it agood choice in many different kinds ofnetworking environments.A client transactionbecomes distributed if it invokes operations inseveral different servers. The general elements oftransaction processing are data capture andvalidation, transaction-dependent processing stepsand database maintenance. DatabaseManagement Systems (DBMS) are among the mostcomplicated applications. While DBMS maintainsall information in the database, applications canaccess this information through statements madein Structured Query Language (SQL), a languagefor specifying high-level operations. This systemintends to build a distributed transactionmanagement systemfor store ordering withrecovery control to guarantee the consistency ofdatabase.The servers accept the order oftransactions and then manipulate the transactionsto reach the goal.When the server crashes orconnection fails, the uncommitted transaction issaved at the client store as the recoverable objectsand will undo at the next time for databaseconsistency.This paper intends to apply twomethods for distributed transactions: namely FlatTransaction and Two Phase Commit Protocol
