The first step in the process is the compilation of an inventory of the current databases, which include a variety of items from clinical data (for cancer, communicable conditions) to purely operational (Poisons licensing) and administrative information (Food complaints, prosecutions register).

To map the efficiencies to be gained, data custodians and business managers need to be asked about purpose of the database, the scope and contents by data fields, the current size, access rights by various users, platforms, software, data tables used of possible interest to others within Public Health, whether remote access is required and whether redevelopment was being considered or was underway. Finally, additional information on any special requirements for the future and the number and type of staff involved in its operation.

Do not forget to include questions on potential business benefits of integrating with other databases, and potential barriers.
