The Future of Object Oriented Programming

The object-oriented paradigm is based on the idea that objects exist independently of each other, and that operations can be executed on them. Consequently, a user in a true object-oriented development environment should be able to interactively create objects of any available class, manipulate these objects and call their interface routines.· Platform independence – “Write once – run anywhere” capability

As a matter of fact you cannot run a java program ‘anywhere’ unless there is a virtual machine. But its as good as anywhere. Also I know some folks who would say its “write once debug everywhere” but any such platform dependent bugs are probably VM issues. All in all this platform independence is a huge plus point for enterprise development saving tons of cash and effort in porting products.

· Ease of use

I’m not really sure how many hard nut programmers would agree with me but programs are easy to visualize when they are object oriented (once you get the hang of it). After the concept is built, it becomes much easier to realize it in code.

· Free runtime/compilers/tools

This was one of the best moves by Sun. The runtime is free, the development kit is free and now there are a ton of other tools built with java for java that are free. This makes java development easy and affordable.

There are a number of ways to measure the popularity of a programming language, for example, based on the number of:

  • New applications written in the language
  • Existing applications written in the language
  • Developers that use the language primarily
  • Developers that use the language ever
  • Web searches
  • Available jobs that require skills in the language
  • Developers’ favorites

Java has some other advantages as a teaching language

Low cost. The tools needed to build and test Java programs

are available without charge. Sun makes the Java Development Kit (JDK) available over the Internet, where faculty and students alike can download it. The JDK-which includes the Java compiler and interpreter, among other tools-is admittedly spartan, but students should find it adequate for most programming assignments. Those willing to spend a little money will find nicer program development environments (such as Symantec Café and Microsoft J++) available at moderate prices.

Easy to test. Students can put their programs-written as applets-on their Web pages for instructors to test and critique. Instructors can monitor a student’s progress at any stage by simply visiting the student’s Web page.

Student enthusiasm. Java has gotten so much publicity

that students are bound to be excited about learning it. By harnessing that enthusiasm, instructors can use Java as a vehicle to teach students a tremendous amount about modern-day computing. Students will be motivated by Java’s growing importance in the “real world.” Moreover, students will be thrilled by the ease with which they can build sophisticated GUI programs.

Suitable for advanced courses. After students gain

familiarity with the basic features of Java in CS1, they can use its advanced …

Importance of Back-End Web Development

While creating a new website, developers have to focus on both frontend and backend development. The frontend of an application refers to the code that is visible to the website visitors. Normally, frontend code creates interfaces through which the application interacts with the users. On the other hand, the backend code interacts with the server, and delivers content or data to be displayed to the users. So the backend code deals with the application as well as the web server and database. The combination of application, server and database makes the backend coding both complex and important.

Why Developers Must Pay More Attention to Backend Web Development?

Facilitates Information Exchange

As noted earlier, backend consists of three key elements of a website, i.e., application, web server and database. While accessing the user interface of a website, each user is required to provide his login id and password. The login id and password provided by the user is validated by the backend. Likewise, any information submitted by the user is stored in the databases through the backend code. Also, the backend retrieves information from the database, and sends the information to the user interface for displaying to the user. Hence, the backend of a website acts as its structure and facilitate information exchange.

Runs in Various Environments

Nowadays, businesses deploy websites and web applications in a number of environments. For instance, some enterprises prefer running websites on web servers, while others deploy web applications in the cloud. At the same time, many businesses even combine both hosting options to avail benefits like enhanced performance and scalability. The web server setup varies from one network to another. Also, the programmers often distribute server-side workload over multiple machines. The varying hosting environments make it essential for developers to customize the backend of websites.

Contains the Application Logic

Most programmers nowadays keep the user interface and application logic of a website separate to simplify its development and maintenance. In addition to including the domain and infrastructure components of an application, the application logic also performs the routine data processing required by each business. The backend of a website contains its application logic. Hence, the developers must focus on backend web development to switch from one frontend to another seamlessly, and make multiple user interfaces access the same application logic.

Adds Utility to Each Frontend Functionality

While developing a website, programmers are required to write backend code to add utility to each frontend functionality. For instance, they have to write code using a server-side programming language to add functionality to a user login form. Each time a user enters his login credentials, the backend code will collect the values, and compare them with the login data stored in databases. Likewise, backend code also adds functionality to various forms, profiles and accounts. Hence, no website can function without quality backend code.

Impacts the Website’s User Experience

The usability and user experience of a website impacts its popularity in the longer run. As noted earlier, all tasks …

Properties Of A Good Computer Program

A program can be termed as a set of instructions that help in running things. For a computer to perform certain required tasks, it requires an appropriate program. When correct instructions are fed to the computer, then its performance will at most times be at optimum, whereas the opposite is likely to mess things up.

Today many businesses require computers to ensure smooth running of business. Therefore, the computers should have programs that are user friendly and easy to understand. A few things will tell if a program is good enough.

Is it readable

If the program is in writing that makes it easy for a user to understand and follow the logic, then it can be termed as good. It should also have a systematic arrangement that will make it easier to troubleshoot the computer if anything goes wrong.


Your program should save you time. For you to process instructions you will need time and will certainly use up some memory. A good programming is that which works with less processing time and a small amount of memory. This proves efficient as you realize less waste.


A good program should be able to accommodate different platforms, without having to make major changes to coding and software. It is common phenomenon today to see different platform changes.

Therefore, having a portable program will not be affected if the user decides to change the operating system. When good computer programming is done, your system is able to handle modification, which happens due to many reasons like change of administration.

It should only have simple codes that facilitate different amendments needed over time.

Proper structure

For a program to be developed, the major tasks that are required to run the different systems should be broken down. A developer can also develop them independently in order to accomplish the job assigned to them without having to rely on other subtasks.

Proper documentation

Every program has to have good documentation especially if the author will not be around for long. This is so that the other person handling it will find it easy to comprehend.

Many people make computer programming their career. These are the best people to get good programs from. Having a reliable source for the program will give you the satisfaction that the vendor will be there in case any concerns arise. Having one specialist like this in your business especially in the IT department will ensure that your systems run efficiently.…

A + offers advantages, of …

Basics and Criteria for Good Software Programming

A program is a set of instructions or commands to be executed by the computer to accomplish some task. A program involves code for solving a problem and also good documentation which would be a guideline to anyone who tries to understand the program.

An algorithm is a formula, a method, a recipe, a step by step procedure to be followed in order to obtain the solution to a problem.

Conversion of an algorithm to a program in a programming language following the syntax and semantics of that language is defined as a code.

Syntax is the correct method or grammar of writing a command or series of commands which are pre-defines by that particular programming language. Semantics is the logical meaning of a program or series of commands, separate from the grammatical structure. The computer detects syntax errors but does not detect logical errors.

What are the Criteria for a good program?

  • It should be correct i.e. output should be as per the specifications
  • It should be reliable; it should function accurately for a long period of time and also function correctly over all ranges and combination of data.
  • It should be robust; unwanted inputs or data should be identified and proper error message should be flashed. It should never crash.
  • It should be user friendly with enough comments, tips, on-line help and short cut options.
  • It should be efficient, with minimum memory and quality output in acceptable time span.
  • It should be readable i.e. it should be simple so that it can be understood to make changes and enhance it if required.
  • It should be portable so that program can be executed on different machines and environment.
  • It should follow all standards and have proper documentation.

Algorithmic Decomposition Versus Object-Oriented Decomposition

Traditional programming techniques have used algorithmic decomposition. Algorithmic or functional decomposition views software as a process. It decomposes the software into modules that represents steps of a process. These modules are implemented by language constructs such as functions in C. The data structures required to implement the program are a secondary concern, which is addressed after the project has been decomposed into functional modules.

Object-oriented decomposition views software as a set of well-defined objects that model entities in the application domain. These objects interact with each other to form a software system. Functional decomposition is addressed after the system has been decomposed into objects. An object is an entity that performs computations and has a local state. It may therefore be viewed as a combination of data and procedural elements.

Object-oriented approach is a method of implementation in which

1) Objects are the fundamental building blocks.

2) Each object is an instance of some type or class.

3) Classes are related to each other by inheritance relationships.

The principal advantage of object-oriented decomposition is that it encourages the reuse of software. This results in flexible software systems that can evolve as system requirements change. It allows a programmer to use object-oriented programming languages effectively. Object-oriented decomposition is also more intuitive than algorithm-oriented decomposition because objects naturally model entities in the application domain.

Object-oriented design is a design strategy where system designers think in terms of ‘things’ instead of operations or functions. The executing system is made up of interacting objects that maintain their own local state and provide operations on that state information. They hide information about the representation of the state and hence limit access to it. An object-oriented design process involves

designing the object classes and the relationships between these classes. When the design is realised as an executing program, the required objects are created dynamically using the class definitions.

Object-oriented systems should be maintainable as the objects are independent. They may be understood and modified as stand-alone entities. Changing the implementation of an object or adding services should not affect other system objects. Because objects are associated with things, there is often a clear mapping between real-world entities (such as hardware components) and their controlling objects in the system. This improves the understandability and hence the maintainability of the design.

The two approaches are similar in that both believe that the way to develop a complex system is by using the philosophy of divide-and-conquer; that is break up a complex software design project into a number of simpler subprojects, and then tackle these subprojects individually. The two approaches disagree on how a project should be decomposed.…

What Are the Advantages of ABAP That Make It the Fundamental Language?

The Advanced Business Application Programming (ABAP) is a high-level programming language used for programming SAP Application Server. ABAP has a wide array of capabilities and efficiencies encompassed into it. Most of the developers and consultants use ABAP for developing SAP applications for their prestigious clients. After knowing the advantages of ABAP, each budding programmer would want to learn ABAP and excel in his/her career. If you are interested in learning the programming language, enroll in the online SAP ABAP Training Courses.

Pioneers in SAP say that it is always wise and smartest choice to use SAP’s own language ABAP to develop SAP applications. Let’s now explore the advantages of the ABAP programming language.

The power of Macros in ABAP is enormous

For huge programs, modularization methods make programmer’s life very easy and simple. SAP’s ABAP witnesses the usage of many modularization models in form of macros and routines. In ABAP, macros or modularization starts with DEFINE and ends with END-OF-DEFINITION and can be called any number of times in the program. Macros can also be used to specify formulae used for high end logical calculations. Usage of macros or routines in the program increases readability, flexibility, meaningfulness, and significance. The power of macros lies in how well the programmer uses its versatility and replaces it in the relevant places of coding.

ABAP is event-oriented language

The SAP applications developed using ABAP do not start and stop on their own. They always require user interaction or other events that are triggered by other running programs. As it requires user interaction, the users have a great command over the language. However, other languages need a complex logic and coding to achieve similar event-oriented programming.

ABAP provides better database management

When it comes to business, it is not only a single database that you use to generate reports or perform analytics. It is always a mixed type of essential data or records that is present in many number of databases. SAP along with ABAP provides logical ways to define, manage, and manipulate databases in a more effective manner. The tables are created in such a way that it can be mapped to any number of virtual objects and called upon whenever required.

One other important reason for wide usage of ABAP is that it was specifically developed for distributed applications. ABAP language gives immense flexibility to the SAP applications such that the distributed systems unify diversified databases as per requirement. Hence, ABAP concentrates more on application and database integration such that all the data utilities are intact and distributed properly.

These are the few notable advantages of SAP’s ABAP. Aspirants who would like to learn more about ABAP can take up classes conducted by highly professional SAP ABAP Training Institutes. The job opportunities for this programming language is enormous in the current market and it is the right time for the aspirants to enroll in the online SAP ABAP Training Courses and improve the confidence level.
