Assignment Task:
Data Security and Management, Security Issues, System Interface, Design System Features, and Functionality.

Security Issues.

Describe the security issues the Dig Brother database may encounter, how and why these should be dealt with and what countermeasures you would take to protect the organisation. You should justify each of your choices and support your answer with examples relevant to the case study. Examples not relevant to the case study will not accrue marks.

Data Security and Management.

The security of the organisation’s data is of high priority and the interface for their custom software may include a variety of tools to provide additional protection. Discuss the possible code-based options for supporting data security within the DB_Central application
in terms of this case study
, including the following:

The error-trapping options available via controls and events on the interface.

The best time – or times – in an application’s lifecycle to check for unsaved data and instigate a save process.

The code features that could be implemented to ensure the risk of accidental loss of data is minimised

Section B: Databases

Normalization

Explain and evaluate the bottom-up technique of Normalization for designing the database to support all the functionality needed for the Dig Brother case study; compare and contrast the bottom-up technique with the top-down technique (Entity-Relationship Modelling) and explain when you would use Normalization and why.

System Benefits

Evaluate the benefits your database solution will provide to Dig Brother, both operationally and strategically.

Section C: Design/Programming

System Interface Design

Create an interface design for the Find Recording component of the system. Your design should be a drawn representation of the proposed interface, clearly showing the layout and type of controls you intend to use (you should label any controls that don’t come with an obvious textual element). The design diagram should be accompanied by a table which contains a full list of all the controls that make up the Find Recording form, specifying their type, the name each control will be known by within the code (the Name property) – which must conform to object naming standards – and a brief summary of the control’s intended purpose within the application and its default setting: how it should appear when the program is first shown to the user.

System Features and Functionality

Describe an additional
substantive
software feature for the application (NOT a database or Internet-based component) which would be of use to the Dig Brother application but is not currently mentioned in the case study. A ‘substantial’ feature would be one that provides an additional piece of functionality requiring an additional custom class, substantive additional code and/ or two or more new interface elements. A single additional checkbox or an about dialog would not count as substantial.
Discuss the purpose and value of the new feature, including a diagram of any new interface elements it may require or descriptions of any additional class objects the application would need to support the additional feature. You should also indicate any objects from the common code library your proposed feature would require.
