All scheduling, viewing, and database management commands must execute instantaneously, except for the following:

• the time to generate a schedule

The time to execute all administrative commands must be instantaneous, except for any delays due to network transmission of data from the central host.

In general, the performace of the Scheduler Tool commands that must access data across a network is subject to potential network delays. The Scheduler Tool must transmit data as fast as is possible on any given network, but delays due to external network circumstances are beyond the control of the Scheduler Tool.

The maximum expected sizes of the Scheduler Tool databases are the following:

• Instructor Database -- up to hundreds of records
• Courses Database -- up to hundreds of records
• Buildings Database -- up to hundreds of records
• Rooms Database -- up to hundreds of records
• Schedules Database -- up to hundreds of records

While there may be on the order of tens of thousands of students and instructors with permission to log in, the expected maximum number of students and instructors logged in at any given time is on the order of hundreds.

The Scheduler Tool must be able to operate with schedules and databases of larger sizes than these normal maximums. However, the tool need not meet the previously enumerated time performance requirements for schedules or databases larger than normal maximum sizes.
