As a web programming language, one of PHP’s strengths traditionally has been to make it easy to write scripts that access databases so that you can create dynamic web pages that incorporate database content. This is important when you want to provide visitors with information that is always up-to-date, without hand tweaking a lot of static HTML pages. However, although PHP is easy to use, it includes no general-purpose database access interface. Instead it has a number of specialized ones that take the form of separate sets of functions for each database system. There is one set for MySQL, another for InterBase, and another for PostgreSQL—and others as well.

It isn’t correct to compare Java to PHP. Since PHP is a server-side scripting language whereas Java is a general-purpose language. In other words, PHP is only used as a server-side language where Java is both for server-side and desktop programming language. Moreover, Java is compiled and strongly-typed language. On other hand, PHP is a dynamic typed language. Hence, only for server-side programming, the comparison between Java and PHP makes sense.

PacketLogic has predefined user interfaces that are powerful and easy to use, such as the client and the Webstatistics. However, when the need arises to do something that is not defined in those interfaces, they are not possible for the end user to modify or customize. This is when using an API is very effective. Using the PacketLogic Python API provides access to virtually all the functionality available in the existing user interfaces, but with full possibilities to customize, integrate, and otherwise adapt the interface according to local and site-specific requirements. The PacketLogic Python API is implemented as a Python module, which means writing scripts to interface with a PacketLogic unit is a matter of:
1. Installing Python Python is available for free for all major operating systems.
2. Installing the API The API is available for free as a download from Procera Networks, on Windows and Linux operating systems.
3. Writing scripts

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?

This tutorial teaches how to use the User modeling and profiling service (UMPS). UMPS provides the methodology to enhance the effectiveness and usability of services and interfaces in order to (a) tailor information presentation to user and context, (b) reason about user’s future behavior, (c) help the user to find relevant information, (d) adapt interface features to the user and the context in which it is used, (e) indicate interface features and information presentation features for their adaptation to a multi-user environment

Although C# is derived from the C programming language, it has features such as garbage
collection that allow beginners to become proficient in C# more quickly than in C or C++. Similar to Java, it is object-oriented, comes with an extensive class library, and supports exception handling,multiple types of polymorphism, and separation of interfaces from implementations.Those features, combined with its powerful development tools, multi-platform support, and generics, make C# a good choice for many types of software development projects: rapid application development projects, projects implemented by individuals or large or small teams, Internet applications, and projects with strict reliability requirements. Testing frameworks such as NUnit make C# am enable to test-driven development and thus a good language for use with Extreme Programming (XP). Its strong typing helps to prevent many programming errors that are common in weakly typed languages.

A number of new geospatial viewing tools from major players in the Internet industry have recently appeared on the scene and are taking the geospatial world by storm. Google,Yahoo, Microsoft, and Amazon have all released web-based mapping tools in the recent past, and collectively these new players to the industry have raised the bar for Internet mapping. Although their functional capabilities don’t provide anything we haven’t seen in web offerings from traditional GIS vendors, their emergence has been significant in that they have managed to capture a wider audience. Google, in particular, has emerged as the leader of this pack with it’s recently released Google Maps product which provides a slick, highly responsive visual interface built using AJAX technologies along with detailed street and aerial imagery data, and an open API allowing customization of the map output including the ability to add application specific data to the map.

An emerging trend in Social Networking sites and Web portals is the opening up of their APIs to external application develop- ers. For example, the Facebook Platform, Google Gadgets and Yahoo! Widgets allow developers to design their own applications, which can then can be integrated with the platform and shared with other users. However, current APIs are targeted towards develop- ers with programming expertise and database knowledge; they are not accessible to a large class of users who do not have a programming/database background, but would nevertheless like to create new applications. To address this need, we have developed the AppForge system, which provides a WYSIWYG application development platform. Users can graphically specify the components of webpages inside a Web browser, and the corresponding database schema and application logic will be automatically generated on the fly by the system.
