New databases and query-languages are created every year. Developers using these technologies have to learn all the different ways to access the databases. When using a query-language to retrieve information it is easy for the query to become really long and complex.Different ways to implement an abstraction layer on top of databases was investigated. By looking at what is easiest to learn and use a Java implementation was used. In the resulting implementation the developers could create a query-object which is sent into a converter which creates the correct query-syntax. After showing the implementation to different developers at Cinnober they felt that an abstraction layer like this one could be really useful. The solution would provide a uniform way of creating queries and that it would be easier to use and understand once you got used to it. The performance of the implementation was high enough for the standards set by Cinnober, it was also deemed easy to understand which was an important criteria for usage in production. A new way of communicating to databases is presented and could be used in production if developers chooses to improve the current implementation.
