Application server - Application server An application server is a server computer in a computer network dedicated for running certain software applications. In the latter part of the 1990s, it was thought that a massive shift over to centrally served applications was likely, and that the desktop PC would be replaced by lightweight network computers. This was, in fact, a return to the much older model of computing as it was done in the 1960s, with a large, very expensive central computer being accessed by multiple users using dumb terminals. The difference now was the widespread use of the GUI. Certain products, such as Citrix's WinFrame, became quite popular, allowing standard Windows software to be run on a NT server, and accessed from a wide variety of clients, including.
Active Server Pages - Active Server Pages Active Server Pages (ASP) is Microsoft's server-side technology for dynamically-generated web pages that is marketed as an adjunct to Internet Information Server (IIS). ASP has gone through four major iterations, ASP 1.0 (distributed with IIS 3.0), ASP 2.0 (distributed with IIS 4.0), ASP 3.0 (distributed with IIS 5.0) and ASP.NET (part of the Microsoft .NET platform). The pre-.NET versions are currently (2002) referred to as "classic" ASP. In the latest classic ASP, ASP 3.0, there are six built-in objectss that are available to the programmer, Application, ASPError, Request, Response, Server and Session. Each object corresponds to a group of frequently-used functionality useful for creating dynamic web pages. Pages can be generated by mixing server-side scripting code (including database access) with HTML and client-side code..
Apache HTTP Server - Apache HTTP Server Apache HTTP Server is an open source HTTP web server for Unix platforms (BSD, GNU/Linux, and UNIX systems), Microsoft Windows, and other platforms. The author claims the name was initially chosen as a catchy name in order to be original, but the most widespread interpretation (which almost immediately surfaced) is that the name comes from the fact that when it was developed in early 1995, it consisted of changes in the code to the most popular HTTP server of the time, NCSA HTTPd 1.3 and was therefore "a patchy" server. It would later be rewritten from scratch and no longer contains any NCSA code. Apache features highly configurable error messages, DBMS-based authentication databases, and content negotiation but has been criticized for its lack of GUI.
Client-server - Client-server A client-server computer network application is one in which a client, thin client or fat client, which instantiates the user interface of the application, connects with an application server or database system. When a client connects directly to a database system, or to a monolithic application server, the architecture of the application is a 2-tier architecture. In recent years, it is more common for a thin client which does not incorporate business logic, but only user interface elements to connect to an application server that implements the business logic, and which transitively (i.e. in turn) communicates with a database server, which stores the raw data used by the application. Such an architecture is called a 3-tier architecture, which is a special case of n-tier architecture. In.
Server-side scripting - Server-side scripting Server-side scripting is a web server technology in which a user's request is fulfilled by running a script directly on the web server to generate dynamic HTML pages. It is usually used to provide interactive web sites that interface to databases or other data stores. This is different from client-side scripting where scripts are run by the viewing web browser, usually in JavaScript. The primary advantage of server-side scripting is the ability to highly customize the response based on the user's requirements, access rights, or queries into data stores. VBScript is used for both server-side and client-side scripting, but primarily server-side. This version of Visual Basic is supported primarily on Microsoft platforms. In the "old" days of the web this was almost exclusively performed.
Server - Server A server in computing is: A computer software application that carries out some task on behalf of users. This is usually divided into file serving, allowing users to store and access files on a common computer; and application serving, where the software runs a computer program to carry out some task for the users. This is the original meaning of the term. The term is now also used to mean the actual computer on which the software runs. Originally server software would be located on a mainframe computer or minicomputer. These have largely been replaced by computers built using a more robust version of the microprocessor technology that is used in personal computers, and the server term was adopted to describe such microprocessor based machines..
Microsoft SQL Server - Microsoft SQL Server Microsoft SQL Server is a database management system produced by Microsoft. It supports a dialect of SQL, the most common database language. It is commonly used by governments and businesses for small databases, and competes with other SQL databases such as MySQL and PostgreSQL for this market segment. The codebase for Microsoft SQL Server originated in Sybase SQL Server, and was Microsoft's entry to the enterprise-level database market, competing against Oracle, IBM, and Sybase. The first version was SQL Server for OS/2 (about 1989) which was essentially the same as Sybase SQL Server 4.0 on Unix, VMS, etc. About the time Windows NT was coming out, Sybase and Microsoft parted ways and pursued their own design and marketing schemes. Later, Sybase changed the name of.
Java Database Connectivity - 4 Additional Resources Types of Drivers There are commercial and free drivers available for most relational database servers. These drivers fall into one of the following types: Type 1 driver Type 2 driver Type 3 driver Type 4 driver Overview of the API JDBC allows multiple implementations to exist and be used by the same application. The API provides a mechanism for dynamically loading the correct Java packages and registering them with the JDBC Driver Manager. The DriverManager is used as a connection factory for creating JDBC connections. JDBC connections support creating and executing statements. These statements may be update statements such as SQL INSERT, UPDATE and DELETE or they may be query statements using the SELECT statement. Additionally, stored procedures may be invoked through a statement. Statements are one of.

Each resource has its own manager. The resource manager typically has its own API for manipulating the resource, for example the JDBC API used by relational databases. In addition, the resource manager allows a TP monitor to coordinate a distributed transaction between it and other resource managers. Finally, there is the application which communicates with the TP monitor to begin, commit or rollback the transactions. The application also communicates with.

Java 2 Platform, Standard Edition - 2 Platform, Standard Edition or J2SE is a collection of java Application Programming Interfaces targeting Java platform applications running on a workstation. General APIs java.io Routines for normal input and output. This includes streams and filehandling. java.lang Contains classes thought applicable to most java programs. This package contains standard java types like Integers and Strings as well as basic exceptions, math functions, threading, security functions, as well as some information on the underlying native system. Classes in java.lang package are always available to the programmer, without needing a special import declaration at the beginning of a sourcecode file. java.lang.ref Special routines for interacting with the garbage collector. For example, one can create a weak reference, which allows one to refer to an object, without preventing the garbage collector from cleaning it.
Java Servlet - a software developer to add dynamic content to a web server using the Java platform. The generated content is commonly HTML, but may be other data such as XML. Servlets are the Java counterpart to dynamic web content technologies such as CGI or ASP. However, unlike CGI, (but like PHP), it has the ability to maintain state after many server transactions. This is done with a combination of HTTP Cookies and session variables (via URL Rewriting). This programming API defines the expected interactions of a web container and a servlet. A web container is essentially the component of a web server that interacts with the servlets. The web container is responsible for mapping a URL to a particular servlet and ensuring that the URL requester has the correct access rights. A.
Jakarta Tomcat - implementation of the Servlet and the JavaServer Pages (JSP) specifications from Sun Microsystems. Tomcat runs with any web server that supports servlets and JSPs. Tomcat comes with the Jasper compiler that compiles JSPs into servlets. Tomcat servlet engine on Apache webserver is an often used combination. Tomcat is also an independent web server in itself and is used in development environments where there are no requirements for speed and transaction handling. Since Tomcat is written in Java, it runs on any operating system that has a JVM. Tomcat is being developed and maintained by members of the Apache Software Foundation and independent volunteers. The source code and binary form of Tomcat is free under the Apache Software Licence. Tomcat 4.x is the latest production quality release, and it implements the Servlet.
JBoss - Boss) is an open source, Java based application server. Because it is Java based, JBoss can be used on any operating system that supports Java. It is open source, but a company (also named JBoss) creates it. The company has a tech consultation service, but the consultants spend half of their time programming. JBoss implements the entire J2EE suite of services. The Sims Online uses JBoss to run its multiplayer games. See also Jetty Tomcat Geronimo JOnAS.
IMS - Function databases Full function, which is basically the same Data Language/1 (DL/I) databases as developed for Apollo. Full function databases can have primary and secondary indexes and are accessed using DL/I calls from your application program. Full function databases can have a variety of access methods, although Hierarchical Direct (HDAM) and Hierarchical Indexed Direct (HIDAM) prevail. The other formats are Simple Hierarchical Indexed Sequential (SHISAM), Hierarchical Sequential (HSAM) and Hierarchical Indexed Sequential (HISAM). Data in full function databases can be stored using VSAM (a native MVS access method) or Overflow Sequential (OSAM), an IMS specific access method that optimizes the channel program for IMS access. OSAM has the advantage that there is special handling in IMS for sequential access of OSAM databases (OSAM Sequential Buffering) which has a performance benefit. 2..
Informix - which developed it. The Informix DBMS developed from the pioneering Ingres system that also led to Sybase and SQL Server. For a time in the 1990s Informix was the second most popular database system, after Oracle. Success did not last very long, however, and by 2000 a series of management blunders had all but destroyed the company. In 2001 IBM purchased Informix in order to gain access to its existing market share and customer base. Long-term plans to merge Informix technology with DB2 have emerged, since the Informix Arrowhead project has now become the DB2 Arrowhead. IBM has also undertaken to support older versions.

InterBase - InterBase would be open sourced, and began negotiations to spin off a separate company to manage the product. When the people who were to run the new company and Borland could not agree on the terms of the separation, InterBase remained a Borland product, and the source code for InterBase version 6 was released under a variant of the Mozilla Public License in mid-2000. With the InterBase division at Borland under new management, the company released a commercial version of InterBase version 6 and then 6.5, and made several updates to the open source code before announcing that it would no longer actively develop the open source project. Two open source forks of the InterBase 6 code, however, remain in active development (Firebird and Yaffil). At the end of 2002, Borland.

Independent Computing Architecture - Independent Computing Architecture (ICA) is a protocol for an application server system, designed by Citrix Systems. The protocol lays down a specification for passing data between server and clients, but is not bound to any one platform. Practical products conforming to ICA are Citrix's WinFrame and MetaFrame products. These permit ordinary Windows applications to be run on a suitable Windows server, and for any supported client to gain access to those applications. The client platforms need not run Windows, there are clients for Mac and Unix for example. ICA is broadly similar in purpose to window servers such as X-Windows, but has a wider scope - it also provides for the feedback of user input from the client to the server, and a variety of means for the server to send.
History of Microsoft Windows - slightly more popular than its predecessor. Much of the popularity for Windows 2.0 came by way of its inclusion as a "run-time version" with Microsoft's new graphical applications, Excel and Word for Windows. They could run from MS-DOS, executing Windows for the duration of their activity, and closing down Windows upon exit (rumor has it that Windows was intended as a platform to run Microsoft Office applications first, and only later as a general-use GUI system). Microsoft Windows received a major boost around this time when Aldus Pagemaker appeared in a Windows version, having previously run only on Macintosh. Some computer historians date this, the first appearance of a significant and non-Microsoft application for Windows, as the beginning of the success of Windows... Version 2 still used the real-mode memory model,.
