The ABC Consulting Corp. contracts for projects that, depending on their size and skill requirements, can be assigned to an individual consultant or to a team of consultants. A consultant or a team can work on several projects simultaneously. Several employees can be organized into a team. Larger teams can consist of a combination of smaller teams, sometimes with additional individual consultants added. This pattern can continue to larger and larger teams. ABC wants to keep track of its consultants, teams, and projects, including which consultant or team is responsible for each project. Each consultant has a unique employee number, plus a name, home address, and telephone number. Each project has a unique project number, plus a name, budgeted cost, and due date. Construct a relational database for ABC Consulting. Hint: You may want to develop an attribute called ‘‘responsible party’’ that can be either a team or an individual consultant. Each project has one responsible party that is responsible for its completion. Or you may want to think of an individual consultant as a potential ‘‘team of one’’

and have the responsibility for each project assigned to a ‘‘team’’ that could then be an individual consultant or a genuine team.
