Storing SHLAA/SHEELA Data - Public forum - Planning Advisory Service (PAS)

We are going to be commencing a review of our Local Plan very shortly. Unfortunately none of the Policy team were in post during the early stages of preparing our recently adopted Local Plan and have not been involved in undertaking a SHLAA or SHEELA previously. We would like to understand what software/programs other Local Authorities have used to store, and easily access, the vast amounts of data (and images) generated by such documents. Suggestions and advice would be much appreciated.
