Group #1

Background

Customer: • Miami Dade College

– 6 Campuses and Multiple outreach centers– Largest College in the US (> 160,000

Students per year)

Problem:• New Federal Government regulations

regarding the disbursement of Financial Aid funds

Objectives

• Provide a system that allows the college to meet federal financial aid requirements

• Allow for the electronic collection of student attendance data without direct instructor intervention

• Make the collected data available to both Staff and Students

• Leverage the College’s existing technology investments

Target Technology Environment

• Microsoft Windows 2000/2003 Platform

• .NET Framework

• Internet Information Server (IIS) (ASP.NET)

• Web interface for students / faculty

• College ID Card (Magstripe)

• Ethernet & TCP/IP for connectivity

Hardware Selection

• Approx 800 Classrooms (some with 2 readers)

• Total 1,000 Check-In Terminals

• Very small off-the-shelf market

• Closest Vertical Market is Employee Time & Attendance

• T&A has several key differences

Hardware Selection

• Typical hardware architecture found in T&A was 1 of 2 types.– Network Attached Smart Devices

(~$1000/unit)– Network Attached Smart Controllers

(~$12,000/20 units = $600/unit)

• Price point of both approaches was very high.

Hardware Selection

• Existing solutions would cost between $1,000,000 - $600,000 for hardware alone.

• Needed to reduce hardware cost.• Build on success of smart controllers and

consolidate processing.• Selected “dumb” Readers ($100) and

Network attached Terminal Servers ($1200/32 readers) = $140/Unit = $140,000

Hardware Selection

• Digi PortServer TS

• IBC SmartMag J

Software Design Considerations

• High Data Volume / Data-Driven Application• Performance Expectations/Requirements and Scalability • Interaction with existing systems at the database level• Initial Attempts at a Pure OO design were inefficient and

offered sub-optimal performance• Final design focuses on a three-tier approach allowing

data-tier to be implemented by off-the-shelf components. • New model offers needed performance at the expense of

OO model at the data layer
