1) Letter to Managing Director. Company: Choice Appointments

To : The Managing Director , Mr Alan Smith

Dear Mr Smith

Thank you for the opportunity to bid for the tender to design a database specifically structured for your organization's needs and specifications.

In our proposal we wish to address the following:

• A network solution that provides data structures for a diverse range of job opportunities across the public and private sectors.

• Incorporate specialist divisions to cater for all work requirements and faster customer service and response times.

• Incorporate temporary/contract and permanent position skills and requirements.

• The ease of change to data if directions of candidates change.

• Database will be able to cater for Choice Appointment's large data requirements including

• Who temporary/contract workers are

• Who permanent employees are

• Who consultants are

• Who the consultant’s contracts are (from client companies and employees)

2) Executive Summary of how we wish to proceed:

1) Define six system elements that comprisey your company framework. This framework (WCA) summarizes the elements of the existing and potential system within Choice Appointments company. The framework suggests that the system is much more than just technology. The system is actually a work system consisting of business processes performed by staff using information and technology.

2) Develop an Entity Relationship Diagram (ERD) model to represent the information requirements of Choice Appointments. We then wish to map this ERD diagram into a set of optimal relations tables eliminating repetition and redundancy of data.

3) We will demonstrate a context diagram of the Choice Appointments’ Information System via:

• Level 0 data flow diagram showing:

1) Major Processes

2) Data Stores

3) Flow of data between processes

4) Create a relational Database

5) Create relationships and enforce referential integrity for all relationships in the Database.

6) Populate the Database with relevant data

7) Create reports as per Choice Appointment requirements; These will include:

• A payslip for a contractor

• An Invoice to a Client

• A list of all contractors that are on jobs, what the job as and who it is for.

• A Brief appointment sheet.

8) Create a User manual explaining all the features of your Database and how to do each task.

9) Data Dictionary which will describe all entities and attributes that are included..

4) Task 2 - A. Database Modelling

Entity Relationship Diagram Model representing the Business Requirements of Choice Appointments

An entity relationship model is a data model for describing the data or information aspects of a business domain or its process requirements, that will be implemented in a database. The main components of an ERD are entities and the relationships that exist between them.

A. ERD set of Relations in 1NF, 2NF and 3NF

Data Normalization is a process to reduce redundancy and duplication within a database. The 3 most common forms or Normalisation are:

First Normal Form 1NF – An entity type that contains no repeating groups of data. Second Normal Form 2NF – An entity type is in 2NF when it is in 1NF and when all of its non-key attributes are fully dependent on its primary key. and Third Normal Form 3NF- An entity type is in 3NF when it is in 2NF and when all of its attributes are directly dependent on the primary key.1NF

Task 3:

Context Diagram for Choice AppointmentsA context Diagram is a top-level view of an information system that shows the system’s boundaries and scope.

The following is the Context diagram for Choice Appointments showing the central Choice Appointments process system and the 4 entities that feed information and data into and out of the system via processes such as payslips and invoices.

A data flow diagram (DFD) shows how data moves through an information system. It provides the logical model that shows what the system does and not how it does it.

Below is the Choice Appointments data flow diagram. It shows the Databases that store information via the rectangles which are open on the right hand side. The processes are depicted via the squares with the round corners and the shaded rectangles depict the entities. Data and information flows from the entities via the processes and are stored in the database repositories. Eg An invoice is sent from the Accounting department to the client. This will update the client information as well as the financial information in the accounting database.
