Data Model and ERD for Alabama Bookstore

System Development for Alabama Bookstore

WATERFALL MODEL

Planning – The Developers gathered relevant information from Alabama Bookstore that will be used for the understanding and development of the system that they need. The Developers interviewed, proposed a project, edit the project if ever there are features that are altered by the Alabama Bookstore, and submit final project proposal to them.

Design – The Developers now understood the needs of the Bookstore thus; they can now develop the desired system of the Bookstore. The Developers designed the features as per fitted for the Bookstore and all of the features must be functioning, they also had tested the system as per developers and reviewed the overall system if everything is well developed.

Implementation – After making sure that the system is functioning well or if not then maybe some bugs are found sooner, the Developers can now deploy and install the system at the company’s place. Everything is put in place and integrated at this stage.

Verification – At the time of using the system, users must verify and evaluate if the system really is a big thing for them. Their works may be done faster than normal ways and the features are running as it must be. Evaluation of the system will give the Developers some hints if they are doing well or some faults are done during the recent phases.

Documentation –The Project is finally presented to the company and at this stage some bugs will be eliminated. The contract then ends and the Developers will give documentation for the system. Manuals will also be submitted to them in order for them to self read how the features of the system will behave.

Script Interview with the Alabama Bookstore

LEGEND:

                SD – System Developers

                C – Client

SD: Good day sir, we are the system developers from Team B IT Firm
SD: May we know your name sir?

C: My name is Martin, but people call me Marvs for short.

SD: So what is your business all about?
C: Our business is a bookstore. Just a simple one that sells books and gives rental services to customers

SD: What are the services that you are offering?
C: Like I said just a while ago, our business is just a simple bookstore that sells books and lets people rent the books.

SD: How many are the users of the system? Admin, Staffs, etc.
C: The only system we will need for our bookstore is a book renting system and a book selling system. No need for an inventory for the books we just need to keep track of the payments, rentals and sold merchandises. All of this are to be managed by a staff and an admin.

SD: What are the features needed for your Bookstore Information System?
C: I already stated them in the previous question.

SD: Do you need any reports generated by the system?
C: Yes, if possible the business needs to generate income and expense reports at a monthly basis.

SD: When is the targeted deadline for your shop and Information System to open?
C: We don’t actually need it to be done right away. The bookstore can function even without these anyway.

SD: So depending on the scope of the system you want us to develop, approximately it will cost       about P100,000 for overall payment.

C:I guess that’s a reasonable price. Then I guess we’ll take it.

1. Download the powerpoint presentation.

2. Form a team to identify the public locations (such as an airport, public library, or café) in your area where wireless LAN connections are available. Visit at least two locations and write a brief paragraph discussing your experience at each location trying to connect to the Internet.

Answer:

            JavaJive, 1.18 Centron Building Eldpidio Quirino, Davao City.

JavaJive is a coffee shop that provides wireless internet connection to customers inside. The customers should buy at least one product for them to get the password for the WiFi. The password is printed in the receipt after a customer buys a product. The customers are able to use the WiFi whenever because the password won't change and even if you don't buy a product in your next visit, you could still use the WiFi but of course you should really buy a product because the WiFi is for the customers. The internet connection has moderate speed, facebooking is not a problem because it loads quickly and the photos are loaded quickly. Youtube is also good but you should really buffer the video because it is slow.

            SM City Davao Quimpo Blvd. SM is a big mall in Davao City that gives free wireless internet connection to visitors. Every devices that are connected are given 1 Hour connection and is refreshed daily. After using the 1 Hour free connection, you cannot anymore load any application or pages because your device is already cut off. The WiFi signal is good in my device when I am in the McDonald's and at the 2nd floor of the mall but some areas has bad signal. Even though there is a good signal in McDonald's, still the internet connection is bad I think this is because of the mass of usage are too many. Facebooking is bad, really bad, I think I'm just used to a fast internet connection that's why I can't handle the slow loading of facebook in SM. You should really wait for a couple of minutes for a single operation to completely load. I did not attempt to open youtube because I don't want to get disappointed so after opening facebook in SM and felt the mini-disappointment, I turned my WiFi off already.
