A Meta model for multiple transaction models

Abstract

The main aim of this report is that of providing a solution which caters for a particular area of the field of transaction management; long running transactions. The inspiration for this thesis was mainly the fact that after an in depth research was carried out, a series of shortcomings in current solutions was noticed. The main issue found is that current software solutions mainly adopt one particular transaction model, and thus a software solution is tied down to providing only one type of transaction management service. This greatly reduces the range of applications which may make use of the software solution, and is considered to be the main issue to be addressed in this thesis: A solution which may provide a transaction management service using multiple transaction models. A secondary issue which has been identified and tackled includes the high complexity involved in building software which uses current transaction management solutions. An effort has been made to create a simple solution which is easy to understand and integrate into the needed applications. Techniques used in order to achieve this include the use of the globally renowned XML language, and the introduction of open source concepts into the proposed solution. The artifact accompanying this dissertation includes the Implementation of the Transit Model Solution, which is an open source transaction management system designed with the intent of solving the issues identified in the current solutions. Ample example applications are also included on the disk. While the implementation is fully functional, its main purpose is that of a working prototype, which proves the novel concepts proposed in this thesis.
