1- What is object-oriented analysis, and how does it differ from structured analysis?

Object Oriented analysis is “the examination of a problem by modeling it as a group of interacting objects. An object is defined by its class, data elements and behavior. For example; in an order processing system, an invoice is a class, and printing, viewing and totaling are examples of its behavior. Objects (individual invoices) inherit this behavior and combine it with their own data elements.” ( (The Computer Language Company, 1981-2012) Object-oriented analysis (OOA) applies object-modeling techniques to analyze the functional requirements for a system.
“Analysis is done by identifying the use cases and detailing a flow of events for each. Also, an initial set of functional test cases is specified, to serve as a vehicle for checking that the implementation is complete and basically correct. Analysis culminates in identifying classes implied by the use cases, and documenting them using an Analysis Class Diagram.” (Russell C. Bjork Professor of Computer Science, 2004)
The difference is in object oriented analysis the data is combined in a process that acts on the data in the object whereas structured analysis treats the process and the data as separate components.

2- Describe the phases of the system development life cycle, and compare the SDLC waterfall model with the spiral model?
“The Systems Development Life Cycle (SDLC) is a conceptual model used in project management that describes the stages involved in an information system development project from an initial feasibility study through maintenance of the completed application. Various SDLC methodologies have been developed to guide the processes involved including the waterfall model (the original SDLC method), rapid application development (RAD), joint application development (JAD), the fountain model and the

The French term,” language” also refers to a specific from of speech .Hence, in the whole process of language teaching, spoken language occupies an important place. Ballard says,” talking comes before writing, oral composition before written composition.(Dash, 2004, p.165-166) Speaking is the productive skill in the oral mode. It, like the other skills, is more complicated than it seems at first and involves more than just pronouncing words Josh Billings says“Silence is one of the hardest arguments to refute”. Learning English as one's second language is not unusual in most places of the world. But learning English as one's second language and mastering it thoroughly is a distinguished achievement. By mastering, I mean that one is able to read, write and communicate unambiguously and effectively. In this case, only a few has accomplished due to many problems such as unavailability of native-English instructors in a country, a totally different language structure used at home and a limited amount of time studying English. The main reason why theFilipinos are employed abroad is their ability to speak and understand Englishand so when all countries in the world struggle to learn English (Rama 2000) We ,Filipinosshould not unlearn it.

Variances

...Advanced Variance Analysis: Calculation and Interpretation Subject: Professional 1 Strategic Management Accounting. Variance analysis is examinable both at Formation 2 (Management Accounting) and at Professional 1 (Strategic Management Accounting) levels. One main difference in syllabus between the two papers is that the Professional 1 (Strategic Management Accounting) syllabus includes ‘advanced’ variances, as follows: • • • • Materials mix & materials yield variances; Sales mix & sales quantity variances; Planning & operational variances; Market share & market size variances. Two issues which students need to master in order to score well in a question on advanced variance analysis are: 1. Accurate knowledge of the formulas. In my experience, examination candidates are much more likely to remember the formulas correctly if they understand the relationship between ‘advanced’ variances and ‘basic’ variances. Therefore, this will guide my approach to the examples in this article. 2. Ability to write a good quality narrative interpretation of the causes of the variances. The golden rule here is that it is not adequate to explain each variance in isolation. Thus, it is not enough to write (for example) ‘this company had an unfavourable market size variance because its actual market share was less than its budgeted market share’. You need to explain the apparent reasons why their actual market share was less than their budget market share, and...

...108 Alipato High School Students’ Reasoning Skills and Their Study Habits and Attitude Towards Learning Maricris B. Acido Introduction A major task of education programs is to come up with guidelines and tools to enable students to learn effectively. This is to ensure that students are able to acquire skills for them to carry out their academic and problem solving tasks. UNESCO acknowledges that: On the eve of a new century, there is an unprecedented demand for and a great diversification in… education, and for building the future, for which the younger generations will need to be equipped with new skills, knowledge, and ideals (UNESCO, 1998). The profusion of knowledge and information has led to an increase in the number of issues that students need to resolve inside and outside the school. Knowledge explosion also demands prudence and careful discernment from students who are to choose more relevant and sound data. This would require the acquisition of reasoning skills that would enable them to filter relevant information from irrelevant ones. Reasoning involves providing arguments, premises, justification, and evidence to claims or positions. However, acquisition of reasoning skills requires much from students. It requires good study habits and positive attitudes, as well as good contextual reinforcers and influences. Many educators have noted that learning is dynamic and that it does not occur in a vacuum. Learning happens due to various factors and influences. ...
