CODE CIS1041

 
TITLE Introduction to Databases

 
UM LEVEL 01 - Year 1 in Modular Undergraduate Course

 
MQF LEVEL 5

 
ECTS CREDITS 4

 
DEPARTMENT Computer Information Systems

 
DESCRIPTION Study-Unit Aims:

- The aim of this study-unit is to introduce students to a background of databases and DBMSs, their use and architecture, concepts of database design and implementation details, and to teach basic skills and techniques in creating, updating and querying databases.
- An introduction to the database approach, characteristics, advantages and disadvantages of using a DBMS is made.
- The candidate is introduced to the principal components and architecture of a DBMS. The processes of database design and implementation, Database conceptualisation, modelling the database, logical and physical data independence, the three-schema conceptual architecture.
- The use and composition of ER diagrams is enforced as an important abstraction for design.
- The relational model and SQL are used throughout this unit.

Learning Outcomes:

1. Knowledge & Understanding:
By the end of the study-unit the student will be able to:

• Evaluate a DBMS through its component parts;
• Understand the main components of a DBMS in terms of functionality and interaction with data storage;
• The role and usage of abstract design;
• The data dictionary approach and its usage for describing a wide variety of database schemas;
• The relative merits and capabilities associated with relational data design;
• The relative merits and capabilities for relational languages (declarative and procedural);
• The capabilities of structural design constructs and triggers to implement a database design;
• The usage and scope of server side programming languages;
• The importance of roles and other management issues associated with a live database.

2. Skills:
By the end of the study-unit the student will be able to:

• Name the main parts of a DBMS;
• List the resources required by each DBMS component and their interaction;
• Aware of the various modelling techniques (ERM and data normalisation up to 3NF);
• Choose and apply a design technique appropriate to a system’s data requirement;
• Apply knowledge of SQL DDL and DML for the specification of tables and constraints, basic updating of data and various query operations;
• Understand the translation of declarative into procedural queries (e.g. in relational algebra);
• Write basic triggers;
• Write basic server side programs.

Textbooks:

• R Elmasri & S Navathe, Fundamentals of Database Systems, Addison-Wesley.
• A manual for a 4GL will be decided in class.
