Introduction To Software Engineering

What is Software?



Software is defined as a collection of set of instructions, often called a program that causes a computer to perform one or more tasks, configuration files which are used to set up these programs and documentation which describe the structure and use of the system.

Types of Software:

1.Generic: Such Software products are developed to be sold in an open market to a range of different customers. They may not provide the exact functionality that a customer requires, but still serve the purpose.

2.Customised: Such software products are developed specifically for a single customer according to his specifications. They give the exact functionality that one needs, but the price of such customised software is likely to be high.

Components of software

Software is a broad term consisting of set of instructions, operating procedures, data structures and documentation.

The Set of instructions, also known computer programs are written in various programming languages, especially designed to facilitate the creation of software. These programs when executed provide desired functions and performance.

The operating procedures are the established methods to be followed in routine for the set up, use and performance of the software system.

The data structures are the set of instruction that enable the program to adequately manipulate the information.

The Documentation is the written text that explains the use and operating mechanisms for computer software.

There are three types of documentation:

1.Architecture/Design Documentation: Such documentation provides an overview of the system. It includes a list of things used in construction of the software, along with a justification on why they are used. For example, a programmer gives the rationale behind constructing a give number of classes and reasons out why a particular class is designed in a particular way.

2.Technical Documentation: When software is created, the code alone is not sufficient. There is some text known as technical documentation along with it that describes various aspects of the operations. It is a documentation that explains the data structures, algorithms and interfaces.

3.End-User Documentation: Such documentation is a manual for the end users, system administrators and support staff. Good user documentation explains all the features of the program, and various steps required to invoke it. It can be in form of a beginner's guide tutorial or a reference guide.
Introduction To Software Engineering
The constantly developing information technologies that all enterprises and companies are using today allow them to seize each new opportunity that arises as far as high performance and productivity are concerned. By enhancing the efficiency of their applied tools, enterprises can increase and maintain their high performance. The implementation of the newest and most advanced solutions as well as the optimal use of the IT investments within a company leads to both ability to seize new business opportunities and development of competitive advantages. However, these efforts must be doubled by an endeavor to find the most appropriate and comprehensive solution for other tasks inside the enterprise, such as designing, testing, constructing and maintaining software. This is what software engineering is all about.

When it comes to performance tuning, software engineering represents a very valuable tool. With computers and IT applications becoming more and more pervasive every day, the role of software engineering is constantly gaining ground. And with companies and enterprises relying more and more on information technology, software engineering is already an indispensable tool in the good functioning of such institutions.

Time is money, and that matters more than anything else within companies and enterprises. Most enterprises make the most appropriate choice of database, yet they fail to reap all the benefits that derive from such a choice, as they do not acknowledge the need to couple the investment in information technologies with software engineering. Performance tuning does not necessarily require that enterprises keep up to date with the latest IT developments. This would be very ineffective in terms of costs, if we were to consider the speed at which the IT world is advancing. Instead, companies and enterprises can choose to upgrade their existing applications and protect their IT investments, and this is where software engineering comes into place. Software engineering focuses on everything from developing database structures to writing consumer-level applications or working on embedded software.

Databases are widely used in enterprises, companies and corporations for the storage of all their necessary information. One of the most widely used and appreciated relational database management systems is the Oracle database. Its popularity mostly derives from the fact that it does not target any specific type of business, and companies of all sizes can benefit from using it. Other strong points of the Oracle database are its flexibility, which derives from its diversity of options as well as the variety of features that each option comes with. However, each company or enterprise has its specific needs and requirements, some more demanding than others, which makes it virtually impossible even for the Oracle database system to meet the needs of all customers. This is how software engineering has come to play a major part in supporting companies to meet the required standards. The entire development and maintenance of software is best handled by an experienced and talented software engineering team. Resorting to software engineering for support with the protection and optimal use of your IT investments is the best and most effective way to enhance your overall performance and maintain a high productivity level.
