CHAPTER III
RESEARCH METHODOLOGY
This chapter presents the research research design, population of the study, sampling design, and data collection method used by the proponents in this this study study.. Results esults of the pre-a pre-asse ssessm ssment ent surve survey y conduc conducted ted are are also also discussed.
Research Design For this study, the proponents opt to use the descriptive type of research. This type of research is conducted to illustrate and determine patterns or characteristics of variables in particular instances or events. The methods used for this research research are primarily a combination of research methods which is an approach to inquiry that associates both qual qualit itat ativ ive e and and quan quanti titat tativ ive e forms forms of resea esearrch. ch. They They gathe gatherred data data through survey and series of interviews.
Population of the Stu! The respondents for this study are the potential users of the proposed system. These include the Colegio’s students, faculty members, admini administr strato ators, rs, and other other person personnel nel.. isit isitors ors of the Colegi Colegio o are are also also eligible to be part of this study.
The total population of students and employees in !etran Calamba is "#$%. The table in the ne&t page shows the distribution of the population.

Sa'pling Design (n order to strengthen the validity of this study, two sampling designs were used to collect accurate information from the list of samples. First, total enumeration was used to obtain data from the employees of the )*+. Total enumeration is preferred in cases which the data population is small or the variable cannot be time-sampled realistically. ince the )*+ has a relatively small population, the proponents deemed that this sampling design is the most eective to use in this /ind of scenario. econd, the proponents also used random sampling in order to collect data from a huge population li/e the students and employees of the Colegio. This /ind of sampling method operates on selected subsets of the target population and using a number of assumptions regarding the distribution of the population, provide estimates of the parameters under study. They used lovin’s formula in determining the sample si0e. This
"
technique is best used when the researchers has no idea about the population’s behavior. The sample si0e aside from the )*+ employees is represented by n which is derived using lovin’s Formula n = >?#@>5e19. AhereB > = Total target population 4 = the margin of error which in this study is #23 n = the sample si0e
Data Collection Metho The

reading
unpublished thesis, and digging related studies and literatures about the present study. The (nternet is another method they used. Aith the use of the (nternet, they browse articles related to the present study. conducted

to
be able
They also to gather
information on the problems encountered in using the manual procedure in developing survey questions. (nternet Research became one of the most important sources of information of the proponents. Through this, they gathered more ideas and signicant information related to the proposed proDect, which are important to the proposed system by means of principles and functions to get more ideas about what would be the possible outcome of the proposed system.
!ibrary research is also a
method used by the proponents since the library is also one of the main sources of information for the proponents to gather information and enhance the /nowledge on the proposed study and the programming language that will use. The proponents also read previous studies in the library to help in terms of data which are fundamental in building theories in developing the proposed system
;
Soft3are De4elop'ent Process The proponents will adopt the (terative Aaterfall *odel for this study. (n this model, iterative process starts with a simple implementation of a small set of the software requirements and iteratively enhances the evolving versions until the complete system is implemented and ready to be deployed. The basic idea behind this method is to develop a system through repeated cycles, in smaller portions at a time. They considered using the (terative Aaterfall *odel for the following reasonsB 5#9 efects at an early phase can be easily identied and evades the downward Eow of the defect 519 Requirements of the complete system are clearly dened already 5'9 The researchers can get reliable user feedbac/ and 5"9 *ore time is given for designing and less for documentation.

Re&uire'ents Gathering$ This stage is where the proponents gathered preliminary data concerning the needs and di8culties being encountered by the )*+. Research has been conducted on how the current process of the C wor/ and the disadvantages of the said process.
Anal!sis$ (n this phase, the data gathered previously are analy0ed to determine the best approach on how to answer the problems that will be of benet to the )*+.
S!ste' Design$ This phase deals with the conceptuali0ing and designing of the system. The proponents create a design model using input-processoutput chart and Gnied *odeling !anguage. These include Gse Case, 6ctivity iagram, Class iagram and equence iagram. atabases were designed using entity-relationship model.
Coing$ (n this phase, the proponents will now proceed in creating the functionality aspect of the system. The functionality that will be provided is based on the obDectives agreed upon by both the proponents and their client, which is the )*+.
Testing$ This part deals with the actual testing of the system before its implementation. The proponents will have the sample derived from target population test the system and give their feedbac/ using a survey questionnaire.
I'ple'entation$ The nal stage of the (terative Aaterfall *odel covers the deployment of the system once all the requirements are met, as well as the overall functionality of the system.
