Angry Technician - thank you very much - I am looking to create an interface to WCBS (once overnight to update info from WCBS) - basic info is; year groups, classes, houses, pupil information, pupil photographs, pupil medical information, next of kin details, teachers and staff, timetable, attendance / absence. I obviously have detail of the fields used for each area. Won't mention that I want to go back into WCBS at this stage in terms of attendance and assessment! would you be willing to have a look at the more detailed doc? I just want to understand how complex it would be and how much time it would take. Fully understand if I get the one figured salute!!
