Introduction
Information System is defined as a technologically implemented medium for recording,
storing, and disseminating linguistic expressions. The study of information systems
originated as a sub-discipline of computer science in an attempt to understand and
rationalize the management of technology within organizations. It has matured into a
major field of management that is increasingly being emphasized as an important area of
research in management studies, and is taught at all major universities and business
schools in the world. Brje Langefors introduced the concept of "Information Systems" at
the third International Conference on Information Processing and Computer Science in
New York in 1965.Information Systems has a number of different areas of work: Information Systems
Strategy, Information Systems Management, and Information Systems Development.
Each of which branches out into a number of sub disciplines, that overlap with other
science and managerial disciplines such as computer science, pure and engineering
sciences, social and behavioral sciences, and business management.
At present there are four types of Information System: Transaction processing system,
Management information systems, Decision support systems and Expert systems.
Nowadays Information System serves a big help for companies, businesses, schools and
other organizations in managing and organizing their data.
This study focuses on an online information system which is basically an information
system in nature; the only difference is that online information system is accessible
through the internet.
The proponents client is the Capitol University Museum of Three Cultures . It was
established in the summer of 2007 and formally opened on May 2, 2008 as a special
dedication to the founder of the Capitol System of Schools, Madame Laureana San Pedro
Rosales, who started her educational apostolate in Mindanao in 1951. That apostolate had
served well three distinct culture groups of Mindanao: the Mranao of Marawi, the

Visayan Christian lowland cultures of Iligan, Cagayan de Oro and Bukidnon, in a
University that today is the home of culture and the arts indigenous to Northern
Mindanao, especially of its lumad culture.
Thus, the raison detre for the name Museum of Three Cultures where NorthernMindanaos three cultures, and ultimately the Mindanao tri-peoples, are traversed in the
life and works of this educators under whose aegis is a concert of unity was reached.
Presently, the Capitol University Museum of three Cultures provides its guest with
different information about the Filipino cultures, it collects and cares for objects of
scientific, artistic, or historical importance and makes them available for public viewing
through exhibits. However, the CU Museum has a problem with their existing system
specifically on information dissemination, information gathering and information
organization
The researchers will design and develop an online information system that would address
the needs of the CU Museum of Three Cultures.

CAPITOL UNIVERSITY College of Computer StudiesBS in Computer Science
This study aims to provide fast and efficient operation for the CU Museum the
proponents will provide solutions to the following questions:
1. How to provide online access to the CU Museum?
The existing system is not accessible through the net; for this reason
gathering of additional information from outside sources is limited
2. How to provide efficiency in information retrieval of the CU Museum?
The current manual system on information retrieval causes this problem;
in effect retrieval of information by the curator or staff takes more time
and gathering of information by the researchers is limited.
3. How to provide information organization?
The present system of the CU Museum has a problem with its file
organization, as a result organizing and managing of file is inefficient.

General objectives
The main objective of the study is to design and develop an online information system for
the CU Museum of Three Cultures. The system will help the Curator manage the
museums data/files efficiently by the end of the semester.
Specific Objective
Specifically, this study aims to:
Develop an online information system for the CU Museum of three Cultures
Provide facility for the system that will reduce the manual effort ingenerating reports
Design a user-friendly environment for fast and easy operation of the
system.
Conceptual Framework
The proponents will be applying Model-View-Controller (MVC) in developing their
proposed online information system. The following paragraphs will discuss more about
MVC its importance and how does it work.
The Model-View-Controller (MVC) is a commonly used and powerful architecture for
GUIs. The MVC paradigm is a way of breaking an application, or even just a piece of an
application's interface, into three parts: the model, the view, and the controller. MVC was
originally developed to map the traditional input, processing, output roles into the GUI
realm:
Input-->Processing-->Output
Controller --> Model --> View
The user input, the modeling of the external world, and the visual feedback to the user are

separated and handled by model, viewport and controller objects. The controller
interprets mouse and keyboard inputs from the user and maps these user actions into
commands that are sent to the model and/or viewport to effect the appropriate change.
The model manages one or more data elements, responds to queries about its state, and
responds to instructions to change state. The viewport manages a rectangular area of the
display and is responsible for presenting data to the user through a combination of
graphics and text.
The model is used to manage information and notify observers when that information
changes. It contains only data and functionality that are related by a common purpose. If
you need to model two groups of unrelated data and functionality, you create two
separate models.
A model encapsulates more than just data and functions that operate on it. A model is
meant to serve as a computational approximation or abstraction of some real world
process or system. It captures not only the state of a process or system, but how the
system works. This makes it very easy to use real-world modeling techniques in defining
your models. For example, you could define a model that bridges your computational
back-end with your GUI front-end. In this scenario, the model wraps and abstracts the
functionality of a computation engine or hardware system and acts as a liaison requesting
the real services of the system it models.
The view or viewport is responsible for mapping graphics onto a device. A viewport
typically has a one to one correspondence with a display surface and knows how to
render to it. A viewport attaches to a model and renders its contents to the display surface.
In addition, when the model changes, the viewport automatically redraws the affected
part of the image to reflect those changes. There can be multiple viewports onto the same
model and each of these viewports can render the contents of the model to a different
display surface.
A viewport may be a composite viewport containing several sub-views, which may
themselves contain several sub-views.
A controller is the means by which the user interacts with the application. A controller
accepts input from the user and instructs the model and viewport to perform actions based

on that input. In effect, the controller is responsible for mapping end-user action to
application response. For example, if the user clicks the mouse button or chooses a menu
item, the controller is responsible for determining how the application should respond.
The model, viewport and controller are intimately related and in constant contact.Therefore, they must reference each other. The picture below illustrates the basic Model-
View-Controller relationship:
The figure above shows the basic lines of communication among the model, viewport andcontroller. In this figure, the model points to the viewport, which allows it to send the
viewport weakly-typed notifications of change. Of course, the model's viewport pointer is
only a base class pointer; the model should know nothing about the kind of viewports
which observe it. By contrast, the viewport knows exactly what kind of model it
observes. The viewport also has a strongly-typed pointer to the model, allowing it to call
any of the model's functions. In addition, the viewport also has a pointer to the controller,
but it should not call functions in the controller aside from those defined in the base class.
The reason is you may want to swap out one controller for another, so you'll need to keep
the dependencies minimal. The controller has pointers to both the model and the viewport
and knows the type of both. Since the controller defines the behavior of the triad, it must
know the type of both the model and the viewport in order to translate user input into
application response.

Cascading Style Sheets (CSS ) is a style sheet language used to describe the presentation
of a document written in a markup language . Its most common application is to style web
pages written in HTML and XHTML , but the language can be applied to any kind of
XML document, including SVG and XUL .
CSS can be used locally by the readers of web pages to define colors , fonts , layout , and
other aspects of document presentation. It is designed primarily to enable the separation
of document content (written in HTML or a similar markup language) from document
presentation (written in CSS). This separation can improve content accessibility , provide
more flexibility and control in the specification of presentation characteristics, and reduce
complexity and repetition in the structural content (such as by allowing for tableless web
design ). CSS can also allow the same markup page to be presented in different styles for
different rendering methods, such as on-screen, in print, by voice (when read out by a
speech-based browser or screen reader ) and on Braille -based, tactile devices. CSS
specifies a priority scheme to determine which style rules apply if more than one rule
matches against a particular element. In this so-called cascade , priorities or weights are
calculated and assigned to rules, so that the results are predictable.
CSS has various levels and profiles. Each level of CSS builds upon the last, typically
adding new features and typically denoted as CSS1, CSS2, and CSS3. Profiles are
typically a subset of one or more levels of CSS built for a particular device or user
interface. Currently there are profiles for mobile devices, printers, and television sets.
Profiles should not be confused with media types which were added in CSS2.
CSS 1
The first CSS specification to become an official W3C Recommendation is CSS level 1,
published in December 1996. Among its capabilities are support for:
Font properties such as typeface and emphasis
Color of text, backgrounds, and other elements
Text attributes such as spacing between words, letters, and lines of text
Alignment of text, images, tables and other elements
Margin, border, padding, and positioning for most elements

The third case also involves dynamic response generated by the use of server side
technologies. There are many server side technologies today. Active Server Pages (ASP):A Microsoft technology. ASP pages typically have the extension .asp. Personal Home
Pages (PHP): An open source technology. PHP pages typically have .php, .phtml or .php3
file name extensions. Java Server Pages: .jsp pages contain Java code. Server Side
Includes (SSI): Involves the embedding of small code snippets inside the HTML page.
An SSI page typically has .shtml as its file extension.
With these server technologies it has become easier to maintain Web pages especially
helpful for a large web site. The developer needs to embed the server-side language code
inside the HTML page. This code is passed to the appropriate interpreter which processes
these instructions and generates the final HTML displayed by the browser. Note, the
embedded server-script code is not visible to the client (even if you check the source of
the page) as the server sends ONLY the HTML code.
Let's look at PHP as an example. A request sent for a PHP page from a client is passed to
the PHP interpreter by the server along with various program variables. The interpreter
then processes the PHP code and generates a dynamic HTML output. This is sent to the
server which in turn redirects it to the client. The browser is not aware of the functioning
of the server. It just receives the HTML code, which it appropriately formats and displays
on your computer.

CHAPTER 3
METHODOLOGY AND DESIGN
Dynamic content was considered in building the application. The researchers conducted
surveys on how the system should appear. The importance of beneficiary satisfaction on
using the system is one of the proponents concern.
For the backend part of the system, the proponents interviewed the curator (beneficiary)
to ask the vital parts that the system should have as function. The proponents then
formulate their own functions and show to the curator what would the system look like in
their own perspective that is base on the curators point of view.
The researcher used the spiral model as their formal methodology in creating the system.
The Spiral Model
Fig. 3.1
As shown in the diagram the spiral model has four main stages. These stages are the ideal
scheme to develop the project for the study to become successful; the researchers must

CAPITOL UNIVERSITY College of Computer StudiesBS in Computer Science
have to understand what are the needs of the beneficiary and formulate the solutions that
would satisfy the needs of the beneficiary.
The following stages were followed in the development of the application:
Iteration #1 Create the application. In the first iteration, we create the Contact
Manager in the simplest way possible. We add support for basic database
operations: Create, Read, Update, and Delete (CRUD).
Iteration #2 Make the application look nice. In this iteration, we improve the
appearance of the application by modifying the default ASP.NET MVC view
master page and cascading style sheet.
Iteration #3 Add form validation. In the third iteration, we add basic form
validation. We prevent people from submitting a form without completing
required form fields. We also validate email addresses and phone numbers.
Iteration #4 Make the application loosely coupled. In this third iteration, we take
advantage of several software design patterns to make it easier to maintain and
modify the Contact Manager application. For example, we refactor our
application to use the Repository pattern and the Dependency Injection pattern.
Iteration #5 Create unit tests. In the fifth iteration, we make our application
easier to maintain and modify by adding unit tests. We mock our data model
classes and build unit tests for our controllers and validation logic.
Iteration #6 Use test-driven development. In this sixth iteration, we add new
functionality to our application by writing unit tests first and writing code against
the unit tests. In this iteration, we add contact groups.
Iteration #7 Add Ajax functionality. In the seventh iteration, we improve the
responsiveness and performance of our application by adding support for Ajax.

Description of the Current System
In this setup the company web server is exposed over the internet enabling the remote
users to access the page. The backend database is connected over the web server but it is
not visible to the outside environment for security purposes.
In client server architecture, this can be classified as a multi-tier architecture. The web
server stands as the middleware for the user and the database.
The following are tier divisions in the application:
Presentation Tier this the topmost level of the application. This contains
HTML (Hypertext Transfer Protocol markups and CSS (Cascading Style Sheet)
that has been rendered by our application.
Business Logic Tier this tier handles request of users by means of posting the
page data back to the server. The server then handles the business logic by means
of database access or any manipulation process.
Data Tier this is the database where any state or data that needs to be persisted.
This commonly separated on a different machine for performance purposes.
Software and Applications applied in the study
Front End:
Web Browser a W3C compliant web browser is needed to render the system
correctly (ie. IE, Firefox, etc).

Backend users these users have the authority to administer the content of the
web application. Backend users are given their own authorization credentials so they
can securely administer the application.
Front end users
o Unregistered/Visitor this are people who visits the website but does not
sign-up for registration.
o Register/Member this are the people who sign-up and has access to
functions that is unavailable for unregister visitor.
SYSTEM METHODOLOGY
Requirements Definition
The user or the visitor of the site should be able to access its contents depending on the
access rules on the site. User can browse though the online objects. He/she can view its
full information and also browse the gallery and other contents of the site. So basically
some part or feature of the sites are only classified or accessible by the register members.
The backend users who will be administering the site will be given accounts to have
access to the administration page. After they have login, they will have access to
administrative privileges that the admin site offers.

The system is design through the principle of MVC pattern. The different
elements of MVC pattern is concern of the different layers of the application. UI which is
the view is the actual output generated by the application and sends it back to user. The
controller is concerned on intercepting the request and executes application and business
logic need for that certain request and renders a view as its output.

Programming Consideration, Issues and Tools
To implement an MVC application the researcher needs a framework that make creating
MVC application easier. In this sense we will only be concern on how we implement our
application in an MVC manner. Visual C# will be the programming language will be used
to execute application, database logic.
Ajax support and client side scripting will be supported on the system. By the use of
JQuery, scripting Ajax and Javascript will not be a problem.
For aesthetics of the application CSS is will be used to style different markups. Some
issues with browsers like Internet Explorer 6 in rendering applications. Cross browser
compatibility like different pseudo classes of different web browser was carefully took by
the researchers.

Configuration and setup for a server for the application must be correct for the
application to run correctly. Listed in the software requirements is the .NET framework
that must be installed on the server in order to render ASP.NET on the HTTP server. The
hardware requirements should be taken seriously for performance reasons like rendering
of the page and faster processing of application logic.
Network bandwidth is also a factor for faster response of request to the users. Choosing
the correct ISP and network setup is a good factor to be considered. Lesser network
latency needs good network equipments (i.e. Switch, Routers); gigabit cards installation
can improve performance of the whole infrastructure.
Security implementations like monitoring of system process, network traffic will be
carefully monitored over the system. Malicious people might use a network script that toflood the network with request that might slow the whole system. Database server
isolation is also considered on the design for public access.
Testing Activities
The researchers implement unit test and evaluation through the code and fix some issues
that are found on the development process. Unfixed issues are listed for further
discussion and bug fixing.
Unit test activities are implemented on each method that is vital to failure (i.e. Input
Validations, Exceptions). Forcing the code to break makes a good practice for minimizing
bugs and errors in application.
Deployment errors, these are bugs that showed up on the deployment application.
Countermeasures for these events are planned through the use of logging (i.e. Event and
Error logging).
Installation Process
Since the company has no previous system, it would be easy to implement or to install
the new system without worrying about data loss and incorrect migration method.
