Creating a Comprehensive Employee Database for KEO International Consultants

In this assignment, the task was to develop a detailed MS Access database to manage employee data for KEO International Consultants. The process involved designing multiple tables, establishing relationships, creating advanced queries, developing user-friendly forms, and generating impactful reports. Each component was crafted to improve data handling efficiency, accuracy, and accessibility.

Designing and Creating the Database Tables

The first step involved defining the core tables necessary for storing employee-related data, including Employees, Departments, Managers, Position, and Salary. Ensuring proper data types was vital. For example, Employee ID was set as an AutoNumber (Primary Key), Names as Text (with validation rules for proper formatting), and Salaries as Currency. Additional tables such as Positions were included to normalize the data, avoiding redundancy.

The Employee table contained fields such as EmployeeID, Name, DepartmentID, PositionID, and HireDate. The Departments table included DepartmentID, DepartmentName, and Location. Managers table linked departmental leadership with EmployeeID, acting as a foreign key establishing relationships between employees and their managers. The Salary table contained SalaryID, EmployeeID, Amount, and EffectiveDate.

Primary keys were assigned appropriately to ensure unique identification across tables. Relationships were created using the Relationships window, connecting EmployeeID from Employees to Salaries, and DepartmentID from Employees to Departments. These relationships maintained referential integrity and allowed seamless data navigation during query formation.

Implementing Data Features Using MS Access

Various features enhanced data validation and presentation. For example, field sizes were carefully set, such as 50 characters for Employee Names. Default values like 'Active' status were assigned where relevant. Validation rules prevented entry errors, e.g., Salary > 0. Additionally, calculated fields, such as calculating annual salary from monthly salary, were created using expressions (e.g., MonthlySalary*12).

Lookup wizard was employed for fields like Department and Position, enabling users to select from predefined options, ensuring consistency. Table formatting was applied to make data more readable, including bold headers and alternating row colors.

Creating Queries to Extract Business Insights

The first query, Employee’s Department, tallied how many employees belonged to each department, displaying DepartmentName and EmployeeCount. The second, Employees Details, prompted users to input an Employee No, then retrieved details like Name, Position, and Salary, facilitating quick individual data access. The Department Managers query fetched employees, their departments, and department managers, with filters like date range or salary thresholds. Sorting by Department No improved data organization. A fourth query identified duplicate employee records to maintain database integrity.

Designing User-Friendly Forms

Two forms were built: a multi-table form combining Employees, Departments, and Managers; and a blank form for manual data entry. Both featured clear titles, such as 'Employee Management Form.' Buttons incorporated features like Save and Reset, with Date & Time displayed in the footer for timestamping. Controls like combo boxes allowed for seamless selection of departments and positions, enhancing usability.

Color customizations involved setting label backgrounds to Light Blue and data fields to Light Orange, improving visual clarity and user experience. These enhancements made data entry intuitive and reduced entry errors.

Generating Professional Reports

Two multi-table reports were produced using the wizard and design view, incorporating the company name 'KEO International Consultants.' These reports displayed data such as employee names, departments, and salaries. The header included the current date and time in a prominent position, while page numbers aligned to the left footer served navigation purposes.

Format modifications included setting a background color relevant for corporate branding, inserting the company logo at the top, and setting the orientation to landscape for better readability. The header fonts used Arial Black for emphasis, and all field alignments were centered to create a professional appearance.

Conclusion

This comprehensive database successfully addressed organizational needs for managing employee data. Through relational design, advanced queries, user-friendly forms, and aesthetically designed reports, the system improves data accuracy, accessibility, and management efficiency. This exercise highlights key skills in database design, query development, and report formatting within MS Access, essential for effective business data management.
