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.

Threads play a major role in applications programming today. For example, most Web servers are threaded, as are many Java GUI programs. Here are the major settings in which using threads has been founded convenient and/or efficient:
• Programs with asynchronous events:
Here the program must be ready for various events, but does not know the order in which they might occur. For example, in Sections 3.1 and 3.2, we have a network server connected to several clients. The server does not know from which client the next message will arrive. So, we have the server create a separate thread for each client, with each thread handling only its client.

Borland Delphi is known to be a great environment for the development of stand-alone and client-server applications on the Microsoft Windows platform. Its virtues range from full OOP support to visual development, in a unique combination of power and ease. However, the new frontier of development is now Internet programming. What has Delphi got to offer in this new context? Which are the features you can rely upon to build great Internet applications with Delphi? That’s what this paper intends to reveal. We’ll see that Delphi can be used:
• For direct socket and TCP/IP programming;
• In conjunction with third-party components that implement the most common Internet protocols, on the client or the server side;
• To produce HTML pages on the server side, with the WebBroker and Internet Express architectures;
• As well as to work with Microsoft’s core technologies, including MTS, COM, ASP, and ActiveX.

The ASP.NET team is delivering a framework for generating Web applications that can take advantage of the latest capabilities in client functionality that fall under the general banner of Asynchronous JavaScript and XML (AJAX) and Rich Interactive Applications (RIA). The new Microsoft ASP.NET AJAX addition to the .NET Framework includes a suite of JavaScript libraries (the Client Framework or Client FX) that are the foundation for creating rich behaviors and control­like functionality in the browser. ASP.NET AJAX also includes a set of a server controls and base classes for extender controls (the Server Framework or Server FX) that provides AJAX programming functionality and experiences for ASP.NET Web developers.

Modern Geographical Information Systems (GIS) [1] provide a service-oriented architecture for interacting with geographical data sets and related maps. Web-based GIS systems are architected around the same principles as more general Web service systems based on SOAP [2], WSDL [3], and REST. Mirroring the World Wide Web Consortium and OASIS Web service standards-making bodies, the Open Geospatial Consortium [5] defines open standards for messages, XML data formats, and access protocols that are specific to the GIS community. In addition to OGC-based services, there are many companies (such as ESRI and AutoDesk) that provide proprietary, commercial solutions. Services from these various providers are not normally interoperable.

Everybody who wants to install a web server database but does not know which software is necessary and how it is installed should benefit from reading this text. This text provides all information necessary to get a SQL database for a web server going; it does not go into any detail of CGI programming, nor does it explain the SQL database language. Excellent books are available on both topics, and it is the intention of this text to provide a working platform based on which a user can then study CGI programming and SQL. For getting a small scale SQL system running (not the notorious example of a major airline booking system, or space mission management database) it will be sufficient to have the software described in this text and the documentation accompanying it. The user manual of msql (a database introduced in this text) provides sufficient information on SQL for building your own database.
