Read and analyse the following specification of a sample database domain.
Task 1 Read and analyse the following specification of a sample database domain. A relational database is to be designed for a medium sized Company dealing with industrial applications of computers. The Company delivers various products to its customers ranging from a ("Simple') single application program through to ("Complex') complete installation of hardware with customized software. The Company employs various experts, consultants and supporting staff. All personnel are employed on long-term basis, i.e. there are no short- term or temporary staff. Although the Company is somehow structured for administrative purposes (that is, it is divided into departments headed by department managers) all projects are carried out in an inter-disciplinary way. For each project a project team is selected, grouping employees from different departments, and a Project Manager (also an employee of the Company) is appointed who is entirely and exclusively responsible for the control of the project, quite independently of the Company's hierarchy.
The company assigns a Consultant and a Sales-coordinator who is an expert in the field to Simple Products projects. The company assigns Project Manager and a Consultant and a number of expert and supporting staff to a Complex Project. Complex projects have a budget assign to the project manager. Simple products do not have a budget. An expert can work in multiple roles (project manager, expert, sales coordinator etc).
An objective if this task is to construct a conceptual schema for the specification of a database domain listed above.
It is not allowed to add any artificial identification attributes commonly known as "id" attributes to the specification listed above.
