ST207 Database HELP(EXAM HELP, ONLINE TUTOR)

问题 1.

Describe in your own words (with appropriate illustrations) the approach to database design based on the following (in each case, describe the approach, then outline the advantages and disadvantages from your perspective):

  • The E-R Model
  • The XR Model
  • The UML Model
  • The O/ESG Methodology
  • Normalization Theory

问题 2.

The following are three software systems for which a database is to be designed:

An Inventory Management System

A Lab Scheduling System for users of a computer lab

A Bookshop Manager System for an educational institution
For each system, develop a database specification based on at least three of the five approaches above. Compare the database specifications derived. Compare the methodologies. Which one(s) are you most comfortable with and why?

问题 3.

How important are surrogates in the design of a database? By considering an appropriate example, demonstrate how surrogates may be used in database design.
Compare the UML database model with the E-R model. What are the similarities? What are the differences? You may use appropriate illustrations in your response.

问题 4.

What are the types of user interfaces that may be constructed for end users of a database system? How do they compare in terms of efficiency and convenience?
Outline the steps to be taken in the construction of a user interface for end users of a database system.
Referring to revision Question 2 of the previous chapter, propose a user interface model for any (or all) of the following:

An Inventory Management System

A Lab Scheduling System for users of a computer lab

A Bookshop Manager System for an educational institution
Identify four different scenarios for development of a user interface for a database system. Recommend an appropriate software development tool for each scenario.
