1. What are the customer’s current applications?

SQL/Microsoft Access is used for automated referral system and to store hospital patient records.

2. Document the customer’s business constraints.

An average of 20 referrals per day for each of 120 offices, or 2400 referral transactions per day.

The project must be done at minimum cost. If PH Network Services cannot complete the project within budget, the project will be cancelled.

High level of availability is a concern.

3. Document any concerns you have about this scenario.

PH's ability to manage this network is a concern because it has no real control over the hospitals or the doctor offices.

4. Identify new applications or old applications that will use the new networking structure.
