The open source world is a frequent topic of debates. Are all internet users ready to move into the open source arena? In fact, are organizations ready to adopt open source for their IT support?

Open source is not a perfect world altogether. With all its amazing advantages, the open source definitely poses certain disadvantages.

The first advantage of Open Source is its free. ‘Free’ has many misconceptions associated with it. A very popular quote related to Open Source is ‘Free as in not free beer; free as in freedom’. Open Source provides liberty; freedom for coding, programming and expanding existing software and also licensing them for others to use. This is highly desirable for coders and programmers who like to build on existing software as well distribute original software with their own license preferences. Thus, Open Source is highly customizable.

The second advantage of Open Source is a solid community support. There exist open source preachers who use only open source software and contribute immensely to spread the use of open source. Open Source has a huge backing from its supporters and it is because of this strong support that numerous useful softwares have come into existence by skilful programming and coding. And this is bound to grow further.

Another plus for Open Source is that it is not limited by patents or copyrights. It is governed by flexible licenses which are independent of geographical locations and can be used all over the world. A user can use, expand a software and attach a license as specified by its creators and release it into the community. Thus, license management is far simpler in Open Source.

Apart from all this, Open Source is highly secure, fast, network-friendly and reliable. Hence, generally people who work into development or server administration are more bent towards using Open Source software.
Despite all these important advantages, certain disadvantages limit the use of Open Source among all Internet users.

Most people find Open Source softwares or operating systems difficult to understand and use. Easy-to-learn and use softwares exist but a general perception that Open Source is relatively less user-friendly has limited its use among general users.

Open Source softwares are relatively harder to install or deploy which is also why people avoid using them.
Many times, certain software does not run smoothly on Open Source operating systems. Thus many softwares are not compatible with the open source environment which is a huge minus.

For huge organizations, open source softwares are not recommended because support and service offered is not as good as the proprietary softwares. Even then many huge organizations are gradually migrating to open source. As of now, one cannot completely bank upon using open source softwares for very huge organizations.

With all the above pros and cons of open source, it is certainly clear that open source is good option for individuals in general who like to stay in free environment that is fast, secure and reliable for their machines. Once they are comfortable with the environment, open source will definitely not disappoint them!

Programing, also referred to as coding, is done by experts who have specialized knowledge in this field. Ordinary computer users like us, who are only concerned with browsing, email, chat. e-commerce, etc, do not necessarily need to do coding. Such programs are fed into the computer during its production stage and that’s what makes the computer operate.
Computer languages are mainly classified into four different categories. Each of these 4 languages have a different way of communicating with the computer. They help the programmer to interact with the computer.

Machine level language-
Machine level language is the lowest level language. Above this comes the Machine Level Language and then the High Level Language. Machine level language is what is understood by computers. However, it cannot be understood by human beings as they are not in any language. They are a mixture of various numbers put together. Machine level language is specific to each computer. Therefore one machine level language program cannot be used in more than one computer without altering it.

Assembly Level Language –
Assembly Level Language comes after machine level language. This language connects to the hardware and the Random Access Memory (RAM) of the computer. This language is used for the operating system and the various drives of the computer, like the hard disk drive which is used as a storage device. These drives are referred to as D, C, E etc in your computer. Each type of central processing unit (CPU) has a specific machine language.

High level language-
High level language is what is coded by programmers. They are in a language which can be understood by humans. There are different types of High level languages. For eg. Pascal, Java, C, etc. There are independent of the machine and the same program can be used in various computers without alterations. All High level languages have to converted into machine or low level language using a converter or interpreter. High level language is not understood by computers in the form that it is. These programs are written in very brief form. Commands are made short so as to ensure faster and efficient execution. There is a style and method that is to be followed and various terms are used in place of commands.

All IT companies do coding for their clients, which are huge companies. Coding can be done only by those who have learnt it professionally. There are various courses which teach programing and anyone who is interested can enroll for it and learn.

i.e. information technology and computer science may have more knowledge about the word programming
and coding. Programming or coding can be done in different computer languages. Commonly used languages
for coding and programming are C, C++, java etc.

Technology never comes to an end what so ever. And that’s the reason why the scope of a career in the field of coding and programming or popularly known as the field if information technology is booming every second day by day. The future of technology lies in the hands of efficient programmer’s and excellent coder’s. Programming and coding can be learnt by anyone but efficient coding is the ability of only talented programmers. Basically a programme is considered to be best depending on various factors.

One of the important factors that is taken into consideration while rating any programme is the runtime that it takes. The programme that takes the minimum runtime is considered to be better than the rest of the programmes. Secondly the length of the code written is also taken into account. It means that the programme whose code is the shortest but at the same time it works and executes at the same time will be considered. A career in programming can help you earn a lot of money if you prove to be an excellent and efficient programmer. Not only that a person who is well versed with coding and programming can make various useful software’s of his own for different companies. He or she can not only earn lots of money but also make a mark in the field of software’s.

Technology is the core ingredient that keeps the world moving. The sooner one realizes this truth the
more successful he or she can become in the long run. One of the many advantages of a programmer is
that it is not at all necessary for him to work in a particular office, he can write his programme whenever and where ever he is comfortable but if has to be the best so that he is in profit.
A truly talented programmer needs only his brains and a laptop and he is all set for his work. He needs to be well aware of the changes that are happening in the world of software’s. He should also be acquainted with the various computer languages so that he can write his programme in the latest language and not end up writing a new and good programme in an outdated computer language that has plenty of errors. A knowledgeable programmer is the need of the hour.

Moreover, there are various domains the software programs are available today and what derives these software programs is the dedicated effort of the so many software programmers. A software programmer is basically the professional who specializes in a specific computer language or tool and is dedicated to developing the various kinds of new and advanced software programs. There are different software programmers that you can find specializing in different domains. However, it is really important to have a good programmer to result in efficient software. It is the programmer who does the coding to build particular software. In addition to the coding, there are various other cycles he needs to perform including the testing of the software to ensure that there are no bugs in the intended software. The software programmer should be able to do programming in such a way as to result in defect free software. The programmer should have an in depth knowledge of the subject he specializes in to create a software that is just matchless and fulfils the needs of the business. The coding and programming are two pillars of the success of the programmer and the software.

Remember while good software can mean beneficial for your business, having software that has many defects can also prove to be harmful for your business. That is the reason a good programmer is very important. It is the software programmer who by means of programing has the ability to drive your business. Moreover, today businesses rely heavily on the different software programs to get an insight into their business. While the right software can give the businesses right view of their business to plan the future course of action in the right manner, the wrong software can lead to various wrong decisions for the business as well. With the heavy use of the software programs today in the different sectors, it has really become very important to have a good programmer. Having the right programmer is the key to drive the future growth for your organization, no matter what sector you are in. With the right coding done, you can be sure to have fulfilled all the requirements of your business in the right manner.

How was all this made possible? The person booking the tickets saw only the home pages of the websites he visited, but behind the scenes there was a mass of computer codes and programs written by experienced programmers who are experts in coding and programing, which prompt the website to respond in a certain way when certain choices are made by the visitor. This is a very challenging and interesting field, and if you can train yourself to be able to do coding and programing, you have got yourself a good career.

How would you get into this career? The easiest way is to do an engineering course, because companies prefer to hire engineers as coding and programing professionals because of their stronger analytical skills. Although computer engineers are most preferred, but most big companies have a well oiled training mechanism which can train you up easily enough. In cas you are unable to crack the tough engineering college entrance examinations, then you could do a course from a professional institute, because many companies also come to these institutes for hiring.

Before you get into a full time job of coding or programing, please keep a watch for opportunities for part time projects. These will not take too much of your time, but they will let you work in a real corporate environment with other professionals, and is a good line to put on your resume. As a bonus, you might also get paid a small stipend!

Make a habit of writing code, in whatever form. It might just be a small widget or a more complicated web application, but the more you write, the more easily you will be able to master the science of debugging codes. This is possible if you start keeping the company of school seniors or family acquaintances who are doing coding or programing work professionally. You can ask them to pass on small jobs to you, which will ease their burden and also help you learn a new thing or two.

Ameos combines UML 2.0 Profile support, MDA® based Model Transformation and the usage of color in a unique fashion. This ensures a higher level of abstraction in the models and target-independent modeling.

UML Support
By implementing the current UML® standard Ameos can be used to describe business processes, to design architectures for SW systems and to model dynamic aspects in State Machines with hard timing constraints. The Model management of the UML is an integrated part of Ameos and allows distributed working, private workspaces and the configuration of new versions. The Ameos Multi-User Repository ensures an appropriate scaling even in large projects.

UML 2.0 Profile Support
Profiles are an easy way to extend standard UML notation and to adapt it to project-specific needs. UML 2.0 describes Profiles and defines how to model them in UML notation. The Ameos Profile Editor allows stereotypes and tagged values to be defined and assigned to model elements of the UML Metamodel, ensuring that profiles are well designed, documented and easy to use for the entire project team.

Color to visualize Semantics
Within Ameos, color can be assigned to UML Profiles and to Model Elements. Wherever such a Model Element is referenced, it shows up in the assigned color. This usage of color on a semantic level, lead to UML models which are far easier to read.

Architecture (MDA) Development
ACDTM is a powerful Transformation Engine, based on OMG’s Model Driven Architecture®. (MDA). The idea behind it is to separate the technical aspects from the domain aspects in the UML. model and generate code from WYSIWYG templates. The main MDA benefits as stated by the OMG are:

Reducing costs of development
Better quality, better ROI
Much faster use of new technologies
Better re-use of domain aspect

Why is transformation of UML Models necessary?
Today many systems are described graphically using the UML which provides several diagram types as well as many graphical and textual elements to capture and model the requirements of a system. While this enables a greater understanding of the user and system requirements, only a small amount of these model elements are typically realized in the implemented system as source code. This leads to models which are constructed to achieve maximum code generation, rather than accurately representing the business or user requirements in a maintainable way. Instead of having a Business Model, this will result in an Implementation Model, which is difficult to read and difficult to maintain. Any change of the target technology or middleware will break the model. The separation of the technical and domain aspects of modeling improves the clarity and reuse opportunities for both these aspects of the design.

Model Driven Architecture
OMG’s Model Driven Architecture, a more sophisticated way of using the UML, provides a solution to this kind of problem. Using MDA, the business is modeled in Platform Independent Models (PIM) which are transformed into Platform Specific Models (PSM). This is carried out in a manner analogous to the use of a compiler to transform C++ or Java source code into an executable program. MDA is not a revolution, but evolution using the next level of abstraction.

As a member of the OMG, Aonix has promoted the idea of transforming UML models to the target environment using Ameos/ACD for the past several years. As a result we have a lot of experience with this approach and many satisfied customers in various industries.

Ameos is available for Linux, Solaris (SPARC), and Windows (2000, XP).

Altova UModelTM 2005 is the starting point for successful software development. Visually design application models and generate Java code, or reverse engineer existing programs into UML® 2.0 diagrams then amend and fine tune your designs and complete the round trip by regenerating code. UModelTM 2005 takes the mystery out of modeling, making visual software design practical for programmers and project managers. It is the simple, cost-effective way to draw on UML.

The Unified Modeling LanguageTM (UML) has become recognized as the 21st-century standard for exposing and analyzing development project requirements and for designing more efficient software solutions. Despite its clear benefits, UML has not been universally adopted because many programming teams were wary of switching to an unfamiliar new technology that may have been perceived as elitist due to the relative high cost and complexity of earlier UML tools. Until recently UML has been positioned as a solution reserved for software architects, but project managers and developers coming from a code-writing background now have a UML tool that is easy to learn and use and is cost effective enough to implement throughout their organizations.

Altova UModelTM 2005 is an affordable UML modeling application with a rich visual interface and superior usability features to help level the UML learning curve, yet it also includes many high-end functions to empower users with the most practical aspects of the UML 2.0 specification. UModelTM 2005 features context sensitive entry helpers, syntax coloring, cascading styles, customizable design elements, multiple layout views, and unlimited undo/redo, coupled with sophisticated modeling functionality such as code generation from models, reverse engineering of existing source code, and round-tripping modified code to update existing models. These capabilities allow developers, including those new to software modeling, to quickly leverage UML to enhance productivity and maximize their results.

Start with the Most Straightforward Diagrams
The UML 2.0 specification, maintained by the Object Management GroupTM (OMGTM), spans hundreds of pages, defining 13 major diagram types and over 1,000 graphical and textual language elements, plus extension mechanisms. UModelTM 2005 simplifies the problem of learning the complex syntax of software modeling by concentrating on the diagrams that are most useful early on in the development process and that yield immediate benefits to programmers, managers, and other project stakeholders:

Use case diagrams
Class diagrams
Object diagrams
Packages
Component diagrams
Deployment diagrams

For instance, the use case diagrams illustrate how an actor – the UML designation of any person or thing – interacts with the system. Use case diagrams can be created in brainstorming sessions that include programmers, managers, and end-users of the proposed system to define and communicate system requirements. Drawing use case diagrams in UModelTM 2005 during your analysis phase helps you record pictorial documentation of requirements that is understandable by programmers and non-programmers alike.

Generate Code from Models
As you proceed beyond use case analysis, you will start to design functional aspects of the system with class diagrams, object diagrams, component diagrams, and deployment diagrams. UModelTM 2005 can generate Java code from these diagram types, immediately accelerating your project.

Some developers use generated code from a quick sketch UML diagram to transition from the analysis and design phase to finished implementation in handwritten code. Others further refine, expand, and add detail to their UML models, then employ a larger portion of generated code in their projects.

Whatever method you choose, you’ll appreciate that the Java code generated by UModelTM 2005 is compatible with Eclipse, Borland® JBuilder®, Microsoft® Visual J# .NET®, and other popular Java development environments. UModelTM 2005 even includes a model syntax checker to detect drawing errors or inconsistencies before they are replicated downstream in code. The Java code created by UModelTM 2005 is defined in customizable templates you can modify to optimize for your compiler or target platform.

Create Models from Code
Altova UModelTM 2005 includes a powerful reverse engineering capability for use in analyzing and extending your existing Java applications. You can import Java code and automatically generate UML models to render a graphical view of your program, its data structures, and their relationships. You can also use this technique to import existing class libraries and create diagrams then apply the libraries in new, modeled projects. Or, you can reverse-engineer an entire Java application to quickly understand it before extending its functionality.

If you currently use Altova XMLSpy® 2005 or Altova SchemaAgentTM 2005 to build XML-centric applications or if you use Altova MapForce® 2005 to address data translation demands, Altova UModelTM 2005 is a natural extension of your development tools arsenal. As you’d expect, UModelTM 2005 imports the Java code generated by XMLSpy® 2005 or MapForce® 2005 and creates UML diagrams so you can model your XML Schema or data transformations as part of larger development efforts.

Get to There and Back Again
As your project evolves, you may choose to make revisions and enhancements either by modifying your UML models or by editing and extending your generated Java code. UModelTM 2005 allows you to synchronize your changes either way. You can round-trip reworked Java to update your UML diagrams, or you can re-generate code from the latest version of your model.
