USEP PRF

The PRF is used during the enrollment, it is where enrollees write the subjects they wanted to enroll in (of course, the class adviser will check if the student is allowed to enroll on all those subjects that the student have written).the data fields in the PRF or Pre Registration Form is not matched with the fields in the Enrollment Interface. There are fields that present in the interface but do not exist to the PRF. The PRF is a form wherein students must fill in with corresponding information needed from them and most especially the chosen subject they want to enroll to.

Keypoints for an effective and efficient network environment ideal for USEP

In system development, how various parts of the system communicate with each other throughout the university? In what way?
Regarding System Development, the best person to ask is our University Programmers, Mr. Fortich and Dr. Mercado.

What are the components involved in the system(s) in the university? (hardware, software, technology, etc.)
I am not in the right position to discuss the details of the software components used as there are other assigned personnel for such job. However, talking about hardware component and technology used, basically I, assigned as the network administrator, is entrusted to maintain our different servers to run 24/7. Currently, we have our Web Server hosted here in our University in our HP ProLiant ML350 Server. Its an old but stable server set-up here in our Networks Office and has been active since Engr. Val A. Quimno , not yet a dean, was appointed as the Network Administrator. The said server has the following specification:

Aside from it, our mail server running under Compaq Proliant ML330 Server, our oldest server, is also hosted here in our Networks Office. Together with other Servers, such as Proxy and Enrollment Servers, both proxy and our enrollment servers are running in a microcomputer/personal computers but with higher specifications to act as servers.

How do these communicate with one another? (topology, network connectivity, protocols, etc.) – may include data flow/ UML diagrams to better explain.

 All Servers are connected in a shared medium grouped as one subnetwork. In general, our network follows the extended star topology which is connected to a DUAL WAN Router that serves as the load balancer between our two Internet Service Providers. All other workstations are grouped into different subnetworks as in star topology branching out from our servers subnetwork as in extended star topology. At present, we are making use of class C IP Address for private IP address assignments. Other workstations IP assignments are configured statically (example: laboratories) while others are Dynamic (example: offices). All workstations are connected via our proxy servers that do some basic filtering/firewall to control users access to the internet aside from router filtering/firewall management. So, whenever any workstation has to connect to the internet, it has to pass through software and hardware based firewall.

What are the processes involved in the communication (each system to other systems)?
 As mentioned above, in item 3, all workstations are connected via a proxy server. It means that whenever a workstation is turned on, it requests for an IP address from the proxy server (for dynamically configured IP address) and connect to the network after IP address is acquired. As connection is established, each system can now communicate and share resources within the same subnetwork and to server following the concepts discuss in your Computer Network Class.
How do you go along with the maintenance of the system?
 Basically, our servers are expected to be in good condition since it is required to be up 24/7. Daily, during my vacant period, monitoring on the servers are observed that includes checking logs, checking hardware performance such as CPU health, etc. If problems are observed, remedies are then and then applied. Once in a week, regular overall checkup is observed as preventive maintenance to ensure not to experience longer downtime if possible.

Does the system follow a specific standard? Explain Please.
As I was appointed as the Network Administrator, everything was already in place except for some minor changes. Basically, different networking standards was already observed such as cabling standards, TIA/EIA 568A-B, different IEEE standards as discussed in your Computer Networks Subject, etc.
How is the security of the system? Are there any vulnerabilities? Risks? Corresponding mitigation techniques? Access control?
 As I have mentioned, we have implemented both software and hardware based filtering/firewall. Basically, Risks or vulnerabilities and different mitigation techniques were considered to increase security in our network. Aside from filtering/firewall, constant monitoring on networks activity also increases the security of the system.

Are there any interference? During what (most) times do these occur? Explain their effects especially with regards to the business of the university?
 Major Interferences are normally encountered as an effect of unforeseen and beyond our control events such as black outs, and the like. The said interference would of course affect University’s day-to-day businesses for obviously this will paralyze all our activities that rely on electricity and further this might cause damage on our network devices, etc. that may later be the reason for longer downtime. Problems encountered by our providers such as connection to the National/International Gateway also affect University’s business such as correlating to University’s Business Partners outside and within the country.

USEP Enrollment System Design

In connection to our first assignment that talks about the processes behind the enrollment system in USEP. Well definitely, knowing the enrollment process in a particular University you are untended to enroll is really important. It is also quiet obvious that the University have provided pictures and diagrams containing the process of enrollment system. However, my question goes in to two categories only. First, are the posted diagrams are consistent? Based on my understanding on the past discussion in some of my subjects, consistency really gives a big impact towards the overall system or shall we say the diagram. It is very important that we should also consider the consistency of its size of the figures, the flow or the process itself and as well as the direction each of each arrows. And because of this, especially for the new students they will find it easy and fast to follow the given process. This is also true to the old students. The second concern of mine is, is it understandable and concise? For the figures and diagrams it is a need to consider its simplicity not in the sense that it is useless. Well, we can’t deny the fact that there are also students who are not acquainted with the different symbols such as the process box and others. So it is also important that we will make it simple and understandable. And concise, meaning is there’s missing information in the diagrams? Because if we missed either one data in the diagram itself, we should also lost the whole information in the posted diagram.

Generally, it is important that we should consider the consistency, concise and understandability of the diagrams because it will serve as a guide of the new and old students.

USEP Enrollment System

Enrollment system is really a need because it holds an important function in every Schools ad University. In other words enrollment system is the must system in a school. When a student is enrolling for a specific course the school requires all the necessary information of the enrollee. Enrollment system is a way that a particular school enables to trace the information of a student. It is extremely useful in the school in the way of making the processes of enrolling much easy. As for the case of University of Southeastern Philippines, you cannot be called as USEpian unless you can’t enroll in this University. Fortunately, there are lots of diagram pictures containing the Enrollment processes posted in the inside the campus especially during enrollment period which gave a big benefit especially for the new student who is willing to enroll. Well, the posted diagrams are easy to understand. As technology changes and as time goes by, we can’t deny the fact that we should also adopt those automation processes for the betterment of our university. Definitely, this is true that the University has already uses automation process but what I mean is how about those organizations in the campus. Are they already uses automated ways in their transactions? Based on my experiences when I was in Tagum Campus was same also with here in Obrero Campus because I enroll for almost four days which is a very big deal for me since it is time-consuming. The paying of fees especially in every clubs and organizations take long queues which really spend more than an hour. As what I have observed during the time of advising, I have noticed that there just few faculty which comes to my mind that it was quiet unfair for them. And it was a big hassle not only for the part of the faculty and also for the students because you may take time and can create meters of line to wait. For what I have knew there was assigned adviser for a particular year level. The other one is the signing of clearances. Based on my experienced also when I was in Tagum campus, we did it individually. We went to the offices individually together with our clearance. And because of this reason, I found it time consuming also and it is also true with those personnel who are task to sign for the clearances. Yes! It’s a good practice here in Obrero because we just give our clearance to our respective mayor however my concern here is “Why should we will not try it in the automation way?” In a way that we will just give our clearance to the assigned personnel and he/she just signed it by looking in his/her pc. And in the pc there are list of student information and all the sort of account data so that we can minimize our time for signing of clearances.
