Database Relational Schema

No/little evidence in documentation or softcopy.

Database implemented but contains no integrity constraints and/or contains major errors. No justifications given. Schema not documented.

Database implemented with minimal integrity constraints. Justifications given but poor. Referential Integrity has error, tables partially matches ERD proposed

Understanding & Problem Analysis

Demonstrates poor understanding of problem. Explanations will be limited and likely to be insufficient to demonstrate that the student understands the work.

Demonstrates limited understanding of problem. Explanations will be limited but sufficient to demonstrate that the student has some very basic understanding of the problem.

Demonstrates adequate understanding of the problem. Some explanations given but likely to be insufficient to demonstrate that the student understands to a reasonable depth.

Demonstrates good understanding of the problem. Satisfactory explanations given and will be able to demonstrate that the student understands to a reasonable depth.

Demonstrates excellent understanding of the problem. Good explanations given and will be able to demonstrate in-depth understanding of the work

Business rules

Business rules missing or irrelavant to case study and database design proposed

Major limitation on business rules / incorrect analysis on case study. Incomplete business rules

Minimal business rules stated with missing constraints and important analysis.

Good analysis on functionalities & constraints. Adequate assumptions. Minor error found

Excellent business rule statement. Demonstrated critical analysis

Marks 0 1 2 3 3.5 4 5

ER Modelling

No evidence in report or softcopy/Incomplete ERD / individual relation missing

ERD missing major constraints & attributes. Assumptions do not reflect the scenario as a complete system.

ERD contains some errors and/or omissions of attributes & constraints. Assumptions acceptable with limitation

ERD has minor errors. Assumptions logical but has limitations on relationship.

ERD contains hardly any errors. Assumptions logical and comprehensive.

Normalization and logical mapping

No/little evidence in documentation or softcopy.Student did not attempt normalisation.

Mapping and normalisation contain many errors and/or omissions. Does not reflect the group relational model

Minor errors in mapping. Most relations will be in 3NF but there may be some normalisation issues. Integration of system relational model has limitation

Mapping done correctly but there may be some minor errors and/or omissions in the normalisation illustration.

No errors in the mapping and normalisation carried out correctly with appropriate explanations.
