ST207课程简介
This course is compulsory on the BSc in Data Science. This course is available on the BSc in Actuarial Science, BSc in Mathematics, Statistics and Business and BSc in Politics and Data Science. This course is available with permission as an outside option to students on other programmes where regulations permit and to General Course students.
This course has a limited number of places (it is capped). Students who have this course as a compulsory course are guaranteed a place. Places for all other students are allocated on a first come first served basis.
Prerequisites
The goal of this course is to cover basic concepts of database management systems, including relational and other types of database management systems.
The topics covered will include basic concepts of the relational model, creating and modifying relations using Structured Query Language (SQL), basic SQL queries using SELECT operator, nested queries, aggregate operators such as GROUP BY, integrity constraints and relations, views, application development using JDBC, Internet protocols such as HTTP and XML, storage and indexing, tree-structured indexing using B+ trees, hash-based indexing, query evaluation and algorithms for relational operations, external sorting, transaction management and concurrency, database schema and normal forms, and overview of NoSQL databases such as key-value stores, document, and graph databases.
ST207 Database HELP（EXAM HELP， ONLINE TUTOR）
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
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?
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.
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.
