Foothills Athletics Foothills Athletics is an athletic facility offering services in Highlands Ranch, Colorado. All property owners living in Highlands Ranch are members of the Highlands Ranch Community Association (HRCA), which has partnered with Foothills Athletics to provide recreation facilities for its residents. Foothills Athletics has been using a spreadsheet to keep track of its personnel, facilities, equipment, and the HRCA members. The spreadsheet has created many redundancies along with several anomalies in adding, modifying, and deleting information. One of the HRCA members has suggested that the athletic facility should create a database to improve data collection that will also remove many of the difficulties that the spreadsheet is creating. Foothills Athletics primary business operations are based on the following:

¦ Personnel: Foothills Athletics has a number of employees, primarily fitness instructors and administrative personnel. Records are kept on each employee, detailing employee name, address, phone number, data of hire, position, and status as either a current or former employee. Employees are assigned a unique four-digit employee ID number when they are hired.

¦ Members: When joining Foothills Athletics, HRCA members are assigned a unique four-digit member ID number. This information along with their name, address, phone number, gender, birth date, and date of membership are recorded.

This is a one-time fee that establishes a lifetime membership.

¦ Facilities and equipment: Foothills Athletics has a variety of facilities and equipment choices. Each facility has a unique room number and a size limitation associated with it. Some of the rooms contain a variety of exercise equipment; all have a serial number that is used for inventory and maintenance purposes.

In addition, for each piece of equipment, the purchase date and the date of its last maintenance are recorded. Each piece of equipment belongs to a specific equipment type, such as elliptical machine, and is assigned a unique three-digit identification number.
