Although Python is a high-level language, it is not English or some other natural human language. The Python translator does not understand “add the numbers two and three”. Python is a formal language with its own specific rules and formats, which these tutorials will introduce gradually, at a pace intended for a beginner. These tutorials are also appropriate for beginners because they gradually introduce fundamental logical programming skills. Learning these skills will allow you to much more easily program in other languages besides Python. Some of the skills you will learn are

Web services, an emerging paradigm for architecting and implementing business collaborations within and across organizational boundaries, are currently of interest to both software vendors and scientists. In this paradigm, the functionality provided by business applications is encapsulated within web services: software components described at a semantic level, which can be invoked by application programs or by other services through a stack of Internet standards including HTTP, XML, SOAP, WSDL and UDDI [3,18]. Once deployed, web services provided by various organizations can be inter-connected in order to implement business collaborations, leading to composite web services.

Solutions | J2EE to .NET 2.0 Migration
Since almost two years, there has been an active debate over the endurance of the two giant enterprise platforms, Microsoft‘s .NET and Sun‘s Java 2 Platform, Enterprise Edition (J2EE). Which technology would emerge as the leading platform for developing new web applications?

Now that the combat has settled down a bit, each platform has managed to capture a substantial share of market for itself. In fact, many organizations have arranged for a strategy for one or the other of these frameworks. But many (e.g. those which have large investments in the legacy systems) are still evaluating the merits of the two platforms. The IT personnel in those businesses is questioning as to what extent would choosing .NET or J2EE influence their host strategy, etc.

The .NET Framework is an integral Windows component that supports building and running the next generation of applications and XML Web services. The .NET Framework is designed to fulfill the following objectives:
• To provide a consistent object-oriented programming environment whether object code is stored and executed locally, executed locally but Internet-distributed, or executed remotely.
• To provide a code-execution environment that minimizes software deployment and versioning conflicts.
• To provide a code-execution environment that promotes safe execution of code, including code created by an unknown or semi-trusted third party.

Delphi/400 is a suite of application modernization tools designed to enable System i application developers to build completely new Web applications or build new Web interfaces to existing applications. For the System/i developer, there is lots of good news. The approach is based on the same notion of holistic application design and user interface / logic separation that System i developers have been using since the box you and I love was once called the System/38 Delphi/400 is the toolset that best addresses the notion of the application factory of rapid application development. It is the natural next step in a progression of tools from those with sophisticated names such as “Intelligent Development Environment,” “Componentization,” and “Visualization.” Yes, It is all of those and more. It does its thing by asking the developer to think about the whole application, not just one Web page at a time. Isn’t that how System i developers already think?

It is a highly skilled work which demands good conception of beauty and much professional knowledge of the program designers. However, it is difficult to fulfill the needs in reality.

The security of information systems is a wide area. Its development followed that of information systems, whose development in turn followed advances in hardware. As computers and software have developed real fast: “To put it quite bluntly: as long as there were no machines, programming was no problem at all; when we had a few weak computers, programming became a mild problem, and now we have gigantic computers, programming had become an equally gigantic problem.” [1], so have developed the possibilities for security breaches.
