We will describe our experiences in developing a relational database application that interoperates with a legacy M-based laboratory information system to maintain a long-term store of laboratory data. While the design of the relational database application per-se was a straightforward task, the integration of this data repository into the pre-existing legacy environment posed a variety of technical and political challenges. We were able to overcome these challenges and hold development costs down to approximately two FTEs by designing our repository in ways that made use of many features of the legacy system including security and patient identification. We are now able to use this repository environment to access historical laboratory data from our site and to merge our data with laboratory data obtained from other laboratory information systems.
