(Feasibility Research Report) [Part2] (3) Analysis of Existing Situation and Systems.
(1) Physical model of existing system: (omitted).
(2) The logical model of the existing system: (omitted).
Narrative:
1. Information exchange between various departments students is mainly manual processing. Artificial activity delivery, not convenient information, query, statistics. Information flow needs to be put in large amount of manpower, time, space, and resources.
2. The workload of the staff is large.
3. The supportive service is poor.
(4) Target system export and analysis.
(1) Target system logic model exported by the logical model of the existing system.
(2) Physical model of the target system exported by the logical model of the target system. (DFD Figure)

Narrative: The target system makes full use of modern computer technology and network technology to improve the flexibility of information processing efficiency, flow rate and information exchange. Save a lot of resources, human, and financial resources.
(5) The technical feasibility analysis of the proposed development system.
(1) The impact of adopting the recommendations of the system:
1. The impact on the device:
a. Since some devices in the target system are not high, many existing devices can continue.
