The BugsCEP software package consists of two main files:
- BugsCEP, software which contains the forms, queries and code that make up the user interface
- Bugsdata, the database which contains almost all of the actual data.
The latter is a relational database built in MS Access 2000, with about 43 tables which contain the data enumerated below.

The setup program will also install a number of support files as needed, including those necessary to run an Access database on a PC without the full software installed.

The vast majority of data has been input by Paul Buckland, including the extensive recent database update (see below).
