INTERNATIONAL ADVANCED DIPLOMA IN COMPUTER STUDIES
MODULE: SYSTEMS ANALYSIS & DESIGN ASSIGNMENT TITLE: HERITAGE RAILWAY MARCH 2011
MARKING SCHEME
Markers are advised that unless a task specifies that an answer be provided in a particular form, then an answer that is correct, factually or in practical terms, must be given the available marks. If there is doubt as to the correctness of an answer the relevant NCC Education textbook should be the first authority.
This Marking Scheme has been prepared as a guide only to markers and there will frequently be many alternative responses which will provide a valid answer.
Each candidate’s script must be fully annotated with the marker’s comments, where applicable, and the marks allocated for each part of the tasks.
Throughout the marking, please credit any valid alternative point.
Notice to Markers Where markers award half marks in any part of a task they should ensure that the total mark recorded for a task is rounded up to a whole mark.
Systems Analysis and Design
March 2011
Final
NCC Education 2011
Note: Markers should be aware that there are several ways to model the system . For full marks candidates should include the features that ensure the system can meet the needs of future expansion, e.g. recording the name of the owner of engines so that extra engines can be borrowed or hired and allowing for new timetables and ticket types. Guide Maximum Marks
