This SIT103 Database and Information Retrieval Assignment are to design and implement a database to support the management and services of the company.
Question 1 (ULO1) Create your own brief description of the following file organisations. You must use several sources for each file organisation to create your description. a) Sequential access b) Random access c) Index sequential access
Question 2 (ULO1) Describe in detail 3 techniques to store and retrieve data using an SQL database. Some techniques are based on SQL statements, and others based on setting the primary key value.
Question 3 (ULO2) Briefly describe the following processes related to the Entity-Relationship data model: a) Gathering business rules b) Normalisation Page
The task consists of the following four parts:
A business rule should be able to identify the entities and the multiplicity of the relationship between the entities. For example, “Onebranch has manystaff members”. The list should cover all business rules applied to the scenario above.
Instruction:Use a dotted item for each business rule. Assume that a movie has only one director.
ER diagram is based on the business rules, and should clearly label all entities, entity attributes, primary and foreign keys, relationship and connectivity. The cardinality is optional.
Instruction:Use professional software (e.g., MS Office Visio) to draw the ER diagram. Crow’s Foot notation is preferable
Data dictionary is based on the ER diagram, and contains all table names, table attribute definitions, as well as their characteristics and relationships that are to be implemented in the database management.
Instruction:Use data dictionary template (e.g., Table 3.6 on page 92, Table 7.3 on page 253 of the textbook, or the example in lecture notes).
Based on the ER diagram and data dictionary, you are required to use SQL to create a database and implement the database functions as indicated below:
