Analysis and Assumption for all Tasks

I analysis this assignment and according to my assumption, in the Research Department has many information and in this Research Department Project.

In this project, there are six entities which are related to each others.Research Department has many projects.A project has many roles, a role also has many projects, so demy appeared and it named projectdeatils.

A project contains many Internal Employees and an Internal Employee also contains many projects. A Project contains many Funding Agencies and a Funding Agency also contains many projects. So the demy appeared and named ProjectDetail.Thus, the table of External Employee, Internal Employees, and Funding Agnecy are relation with a demy table ProjectDetail.

In the Project table, ProjectCode is the primary key. In the InternalEmployee table, InternalEmployeeNo is the Primary key.

In the Internal Employee Form, gather data includes the attributes such as EmployeeNo, FullName, Age, Address, Nationality, Qualifications, EndContractDate. The primary key is EmployeeNo.

In the Internal Employee Form, gather data includes the attributes such as ExtEmployeeNo, EmployeeName, Address, Company, Hours per project, and Cost. The primary key is EmployeeNo.

In the Funding Agency Form, gather data includes the attributes such as FundingAgencyNo, FullName, Address, Contact person, Contact telephone, ProjectName and Amount. The primary key is FundingAgencyNo.

In the Project Form, gather data includes the attributes such as ProjectCode, ProjectName, StartDate, EndDate, EmlpoyeeName, EmployeeType, RoleName, FundingAgencyName, DutyTime, GrantAmount, Outcome, Description, and TotalAmount . In this attributes, EmlpoyeeName, EmployeeType, RoleName, FundingAgencyName, DutyTime, GrantAmount are the repeating group of this Project form. The primary key is ProjectCode.

According to the first normal form, I divNoed single group and repeating group. In the single group, primary key ProjectCode is the key. So, I underlined the primary key ProjectCode. And in repeating group, I added the ProjectCode as a key and I also underlined.

According to the second normal form, I copy the single group and I divNoed the repeating group. In this case, I divNoed External Employee and Internal Employee as EmployeeNo and ExtEmployeeNo. I can Internal EmployeeName if I knew EmployeeNo, and I can External EmployeeName if I knew ExtEmployeeNo.

According to the third normal form, I divNoed both single and repeating group again if can. So, I copy primary key ProjectCode and wrote the attributes that concerns only ProjectCode. But in this form the attributes in the single group are only concerns with the ProjectCode. So, I copied the single group. And then I divNoed the groups. One group is including ProjectCode, EmplyeeNO, ExtEmplyeeNO. And in this group, Role NO and AgnecyNo is included as the foreign key. Other groups are EmployeeNo, ExtEmployeeNo, AgnecyNo, Role.

These groups have the full meaning. For example, I can know ProjectName, StartDate, EndDate, and TotalAmount if I knew ProjectCode. I can know RoleNO, FundingAgencyNo, DutyTime, GrantAmount, Outcome, and Description if I knew ProjectCode, EmployeeNo and ExtEmployeeNo. I can know EmployeeName if I knew EmployeeNo. And I can know internal EmployeeName if I knew ExtEmployeeNo.

According to the optimization, I defined the table name for each groups. They are PROJECT, PROJECTDETAIL, INTERNAL EMPLOYEE, INTERNAL EMPLOYEE, EXTERNAL EMPLOYEE, FUNDINGAGENCY and ROLE.

Finally, I created Data Model. This Data Model is created the tables with relations by the optimization.
