Introduction

Alex Miller A-VCE ICT Coursework Microsoft Access 97 The Problem The adult education class needs a new database as running the courses with books proves a problem. There is a selection of books with each set of data in. This data can become damaged and the staff can forget to update each book. Also as there are a few books, staff has to update each one with the new data, this can become tenuous and annoying. Another point is that there are many different subjects, rooms and tutors that need to be linked together. This can be a problem as some classes can be in different rooms each day of the week. With a book this can be a problem, as the design may not have a feature for this. The new database will put all the data into separate tables and link them all together. This will enable all the tables to function together allowing the user to change the data in one and it will be changed in them all. The user will also be able to run queries asking the database questions. This will enable the user to gather information without having to search through all the data. This can save a lot of time and improve accuracy as human error may be nearly deleted. The database is going to have to incorporate the student's personnel data, the class times and the tutors. The database will be assessable to all the teachers and admin staff so, with little training everyone will be able to finds out important information. ...read more.

The system I will be using The system at school My system at home Pentium 2 350MHz AMD Athlon 600MHz 64 MB 128 MB 6.4 Gig Memory 27 Gig Memory 14" SVGA Monitor 17" SVGA Monitor Microsoft office 97 Microsoft office 97 + Microsoft word 2000 Microsoft Windows 98 Microsoft Windows 98 8MB HND Graphics Card TNT 2 Graphics card Constraints and limitations As I will be doing work at home and at 6th form I may experience a few constraints. For example at home I have Microsoft word 2000 whereas at 6th form they have the 97 edition. This can prove to be a problem, as I cannot take work to and from 6th form to complete at home. This means that I will have to complete all word documents either at home or at 6th form. This is only a minor problem which I can overcome by selecting work to take home as I have access 97 the same as the 6th form. If I know I have to do a word document and I may have to take it home I will do it at 6th form rather than other work which I can take home. I will have to manage my time. My second slight limitation is that other classes in the school often book the computer rooms at 6th form. This can mean that I am not able to work on a computer at certain times. ...read more.
