An Approach to Achieve DBMS Vendor Independence for Ides AB's Platform

Sammanfattning: Software that is developed with few integration capabilities to different user interfaces or database vendors might lose market share in the long run. To stay competitive, companies that find themselves in situations like these might need to look at options to increase their alternatives. This thesis aims to present and evaluate how Ides AB could achieve vendor independence as it relates to database integration.The proposed solution is based on pre-existing code from an existing product and thus includes theory about the methods and details how one can read, understand and analyse code. The outcome is presented with code examples to give the reader a clear and concise understanding. In the evaluation phase, we take other related work into consideration as it relates to our thesis focus. The proposed approach presented consists of a class to represent different database vendors. It also consists of abstract functions handling the interaction between different databases. Which database the class interacts with is determined by the connection established. The approach also includes what is possible to make database agnostic verified by an evaluation.
