Editing the control system database requires that you understand the database structure as covered in previous chapters.

To effectively edit and apply changes to the runtime system, you will need access to both the csadmin and postgres users. The actual editing is performed by the postgres user. The csadmin user is only needed to perform a restart of the control system. A restart is required for new additions and modifications to certain tables.

For the remainder of this chapter, the contract name 'sample1' will be used.
