EER Modelling and SQL

This study material provides an in-depth understanding of EER modelling and SQL. It covers topics such as case selection, enhanced entity relationship diagram, logical database design, table creation, index creation, data population, and SQL queries. The material is suitable for students studying database management or related courses. It includes solved assignments, essays, and dissertations on EER modelling and SQL.

2EER MODELLING AND SQL
Stage 1:
Task 1.1: Case Selection
The database is proposed for a retailer organization named ABC Fashion. The
organization has headquarter which controls all the activities such as internal operation and
sales. The case study not only describes the sales of the products but also provide a detailed
insight of internal processes. The case study is mainly based on the employee management,
branch maintenance and product stock handling. The sales of the products is for supporting
overall idea of the organization. The employee will be working in a branch which has a super
visor. To make the internal processes more clear the organization has chosen the supervisor
from the employees. This categorizes the employees in two categories such as regular and
supervisor. The organization wants to store the address of each user such as employee and
customer separately. The organization sales fashion products like shirts, pants and many
more.
The organizations executes its processes based on the stores in various locations. Each
of the stores has its own inventory. The products are sent to the customers from each of these
stores. The organization wants to store the details of the store from which the products are
sent to customers. The organizations also has different types of jobs. ABC fashion wants to
record new job types, find the stored job types and modify those job types through the
system. The organization wants to have only one supervisor of a department at a time. ABC
is not concerned with finding the past information regarding who was supervisor. The
organization wants only the information on who is currently supervising a store. Regarding
the sales, ABC wants to store the customer orders and the products ordered in the same order.
The inventory related data will be stored for each individual store. This is because the
organization stores product individually.

Task 1.2 Enhanced Entity Relationship Diagram:
The Enhanced Entity Relationship diagram or EER diagram is considered to be the
extended version of the logical database model named Entity Relationship diagram. The EER
models assists in designing the database that has high-level requirements. The EER diagram
shows the generalization and specialization.
