Understanding Software Engineering

It is a systematization of the process of software development to ensure the best solution most economically. Its goal is to produce high quality software at low rate.

Software Engineering is the application of a systematic, disciplined, quantifiable approach to the development, operation and maintenance of software. A typical software development project will need to go through the phase of Analysis, Design, Programming, Testing and Implementation. Software Project Management (SPM), Software Quality Assurance (SQA) and the use of Computer aided Software Engineering (CASE) would run parallel with the other phases and finally comes the maintenance phase. It is always said that more than 80% of the costs go towards maintenance of the software.

Software Methodology

It is a step by step plan for implementing a method using certain tools and procedures. It often describes the entry criteria, exit criteria and checkpoint for each of the activities or components in software engineering. Some of the popular methodologies today are based on structure techniques or information engineering or object-oriented techniques. Methodology selection depends on the nature of the project, the type of application, the tools proposed to be used and the kind of controls and documentation that would be required.

Waterfall, Prototyping, Spiral, Rapid Application, Stepwise Refinement, Industrial and military standards, Assembly by reuse, Application generation, Continuous transformation and Knowledge based software automation are some of the popular methodologies.

What factors would influence the choice of model for software development?

It depends on the nature and size of application, whether it is an in-house development or development through an external agency, the availability of various tools and resources, time frame and budget, etc.

Who is Software Engineer?

A software engineer is someone who applied engineering principles in the co-operative development of software. A good software engineer should not only generate computer programs but also learn the skills to produce good documentation, database and operational procedures for the computer system. He should be well defined about the components or modules of software engineering.

What is the Difference Between a Software Engineer and a Computer Programmer?

The terms software engineer or computer programmer may be confusing to the average computer user. Most of us associate computer programs with the generic term ‘Software’. To us it may seem that the terms are interchangeable. That is not so. The role played by a software engineer is significantly different from that of a computer programmer. Before learning what the difference between a software engineer and a computer programmer is, let us see what is meant by the term software engineering and how it relates to computer programming.

Software engineering is a rigorous approach to development, maintenance and testing of software. These are engineers who must be knowledgeable about software requirements, design, development, maintenance and testing. They must be well versed with the tools and methods used for the development process as a whole. It is thus a convergence of the fields of computer science and systems engineering with a great deal of project management added for good measure. They are expected to have technical skills in addition to managerial skills.

A computer programmer on the other hand, is required to develop, test and maintain code that is to be run on the computer. He is responsible for converting the specifications provided in the software requirements definition phase into working code for the computer. Computer programmers are involved with design and maintenance of websites too. They should be proficient in analysis of programs. They are required to collaborate with manufacturers in developing new methodologies for software with evolution of hardware. Training, documentation and generation of reports are also tasks that should be handled by a computer programmer.

We can observe that the skill set required by a computer programmer is a subset of the skills expected from a software engineer. The computer programmer is a specialist in some areas covered by software engineering. A software engineer is in charge of the overall software development process and is expected to improve the reliability and maintainability of this complex process. A software engineer may have a team of computer programmers working under his supervision.

The 9 Most Unanswered Questions about Appliances

Qualities of the Best Dehumidifier

The search for a home dehumidifier can take its toll on you if you do not know how to go about it. There are so many models to choose from, each with its unique set of features and price point. You should make a point of finding out more about their features and prices.

Dehumidifiers come in many price points. The simple and smaller ones are affordable, and so not need much thought in terms of investing in them. There are also some big and complex ones with many features. You need to think a lot about these before you buy them. You are not limited to which room you can use them in.

It is important for you to determine which features your choice cannot lack. Some of them are so advanced that they can remain functional without stopping for a long time. They can also detect the humidity levels and with turn on or off themselves. IF you would like one of these, you need to look at what energy rating it comes with.

You need to also think of the space you have for the machine. When you are contemplating which one to take; you need to also look at the space it needs to be set up in. You need to the compare this with the area you needed to use it in.

You need to then look at how safe it shall be to use. You need to check whether there is a manual that can help you learn how to use it safely. There are manuals online, apart from what the appliance might be shipped with.

You also need to check what capacity the dehumidifier comes in. This shall be the statement of the amount of moisture the appliance shall take away from the air. This figure is arrived at when there is a measure of the amount of water the device shall have collected from the air in twenty-four hours. You can expect different ratings for the different models in the market. You need to be keen on which model you settle on. You can also find dehumidifiers sufficient for the entire house, which can be connected to the air conditioning system.

There need to be also a consideration for the optimal working environment for the chosen appliance. If a dehumidifier was designed to work in a crawl space; it will most likely not work in a larger area. This is why you need to find one that will suit the area you want it to work in the most.

You can use these dehumidifiers in any room you wish. They can be used in the basement, closet, crawl spaces, bathroom, garage, attic, the ones for entire house, and others. You need to know how much humidity there is to be cleared. With such information, settling for a dehumidifier shall not be that hard.

Top Five Accessible Master of Software Engineering Degrees

A graduate program that awards the Master of Software Engineering degree is not as easy to find as you might think. Many universities today make include software engineering as an area of concentration for the graduate degree in computer science or computer engineering. Software engineering remains an afterthought in many graduate level programs at the high profile schools, although many of those universities offer an undergraduate degree in the field. A degree devoted solely to software engineering is, at the graduate level, often made available only to working professionals. This list of resources for the degree is compiled from schools that have a respected school of computer science, have a manageable tuition structure and offer a terminal graduate degree in software engineering.

New Jersey Institute of Technology is the state’s principal academic institution for technology and management degrees.
