Indeed, shopping online before buying at the point of sale, communications via e-mail and instant messaging, commerce and electronic banking transactions and the use of the computer equipment as “multi – while one” are increasingly part of the routine, and should be taken into account.Most organizations and companies, large and small, are already equipped with a web site, and today we talk more to upgrade than website design. However, such an upgrade is often reflected in the design of a website entirely renewed, because the customer usually adds news and features that require a reorganization of contents and the drafting of a new tree, which justify then a new design. In addition, many micro-sites and promotional sites have become inseparable elements of any successful marketing campaign must be designed so quickly that their life is short, but without compromising on quality.

In this landscape, without reservation on the competence and professionalism of its staff who, during the last ten years, has always been able to go before the changes, trends and innovations, both in the design of technology, allowing it to further the design of the website.

One of the outcomes of this avant-garde vision: the development of innovative technology and exclusive, named ibrid MD, to merge seamlessly, the benefits of a CD-ROM and a website. If you hesitate between these two media, ibrid MD is certainly the best solution!

Web design: the tip of the iceberg

The team is at your service, of course, both to design website for reviewing and upgrading, and for the production and integration of multimedia projects online and offline, which may or not intervene technology ibrid MD, but his offer Website Design would be complete without the realization and implementation of related components such as:

  • Content Management System (CMS content management system)
  • Database
  • Search
  • Mailing List
  • Solution Intranet / Extranet
  • Transaction System
  • Discussion Forum, chat and blog …

Technology ibrid MD

ibrid MD is a patent-pending technology, designed to disseminate content, giving access to both content online and offline through a single interface, with full transparency to the user. In fact, for the latter, ibrid MD seems to act as a CD-Rom which can be updated via the Internet.

Combining indeed benefits of the Internet to those offered by physical media such as CD-Roms, ibrid MD is the ultimate solution to disseminate all your content. More hesitation between the Internet and CD-Rom: join both!

You can physically distribute material on a CD-ROM, allowing you then to retain control over distribution and access to information, knowing that you can change all or part of the content that this CD-ROM provides access, according to the corrections, updates or subsidies that you want to do.

This basic site architecture is fast evolving to serve a wider variety of needs beyond static document access and browsing. The Common Gateway Interface (CGI) extends the architecture-thirds to three by adding a back-end server that provides services to the Web server on behalf of the Web client, permitting dynamic composition of web pages. Helpers / plug-ins and Java / JavaScript provide other interesting Web architecture extensions. Common Gateway Interface (CGI) – CGI is a standard for interfacing external programs with Web servers (see Figure 1). The server hands client requests encoded in URLs to the appropriate registered CGI program, which executes and returns results as encoded MIME messages back to the server. CGI’s openness avoids the need to extend HTTP. The most common CGI applications handle HTML <FORM> and <ISINDEX> commands. CGI programs are executable programs that run on the Web server. They can be written in any scripting language (interpreted) or programming language (must be compiled first) available to be executed on a Web server, including C, C + +, Fortran, PERL, TCL, Unix shells, Visual Basic, Apple script, and others . Security precautions typically require that CGI programs be run from a specified directory (eg, / cgi-bin) under control of the webmaster (Web system administrator), that is, they must be registered with the system. Arguments to CGI programs are transmitted from client to server environment variables via encoded in URLs. The CGI program typically returns HTML pages that it constructs on the fly. Some problems with CGI are: the CGI interface requires the server to execute a program the CGI interface does not provide a way to share data and communications resources so if a program must access an external resource, it must open and close that resource. It is difficult to construct transactional interactions using CGI. The current version is CGI/1.1. W3C and others are xperimenting with next generation object-oriented APIs based on OMG IDL; Netscape provides Netscape Server API (NSAPI) and Progress Software and Microsoft provide Internet Server API (ISAPI). Helpers / Plug-ins – When a client browser retrieves a file, it launches an installed helper application or plug-in to process the file based on the file’s MIME-type (see below). For example, it may launch a Postscript or Acrobat reader, or MPEG or QuickTime player. A helper application runs external to the browser while a plug-in runs within the browser. For information on how to create new Netscape Navigator plug-ins, see The Plug-in Developer’s Guide. Common Gateway Client (ITC) – this gateway allows a third-party application to remotely control the Web browser client. Client APIs Netscape 2.0 (NCAPIs) depends on platform specific native methods of interprocess communication (IPC). They plan to support DDE and OLE2 for Windows customers, X properties for UNIX customers, and Apple Macintosh Events for customers.
Extensions to HTTP. W3C and IETF Application Area HTTP Working Group are working together on current and future versions of HTTP. The HTTP-NG project is assessing two implementation approaches to HTTP “replacements”: Spero’s approach – allows many requests per connection, the requests can be asynchronous and the server can respond in any order, allowing several transfers in parallel. A “session layer” the connection divides into numerous channels. Control messages (GET requests, meta information) are returned in a control channel, each object is returned in its own channel.W3C approach – Jim Gettys at W3C is using Xerox ILU (a variant CORBA) to implement an ILU transport similar to Spero’s session protocol. The advantages of this approach are openness with respect to plug gable transport protocols, support for multiple language environments, and a step towards viewing the “web of objects.” Related to this approach, Netscape recently announced future support for OMG Internet Inter-ORB Protocol (IIOP) standard on both client and server. This will provide a uniform and language neutral object interchange format making it easier to construct distributed object applications.
Java / JavaScript – Java is a cross-platform programming language WWW modeled after C + + from Sun Microsystems. Java programs embedded in HTML documents are called applets and are specified using <APPLET> tags. The HTML for an applet contains a code attribute that specifies the URL of the file compiled applet. Applets are compiled to a platform-independent byte code which can safely be downloaded and executed by the Java interpreter embedded into the Web browser. Browsers that support Java are said to be Java-enabled. If performance is critical, a Java applet can be compiled to native machine language on the fly. Such a compilation is known as a Just-In-Time (JIT) compiler. JavaScript is a scripting language designed for creating dynamic, interactive Web applications that link together objects and resources on both clients and servers. A client JavaScript can recognize and respond to user events such as mouse clicks, form input, and page navigation, and query the state or alter the performance of an applet or plug-in. A server JavaScript script can exhibit behavior similar to common gateway interface (CGI) programs. JavaScript scripts are embedded in HTML documents using <SCRIPT> tags. Similar to Java applets, JavaScript scripts are directly interpreted within the client’s browser and are therefore platform-independent. For a comparison of Java and JavaScript, see here. The Java Language Specification can be found here, a Java tutorial here, the Java Virtual Machine (interpreter) here, the Java Developer’s Kit (JDK) here, and Java FAQs here. A comprehensive Java page of resources can be found at JPL.

As chartered, it has produced Internet-drafts of Requirements for Web Transaction Security and a Secure Hyper Text Transfer Protocol specification Security Extensions For more HTML.

This architecture depends on three key standards: HTML document for encoding content, URLs for naming remote information objects in a global namespace, and HTTP for staging the transfer. Hypertext Markup Language (HTML) – the common language for representation hypertext documents on the Web. HTML had a first public release as HTML 0.0 in 1990, was Internet draft HTML 1.0 in 1993, and HTML 2.0 in 1994. The September 22 1995 draft of the HTML 2.0 specification has been approved as a standard by the IETF Application Area HTML Working Group. HTML HTML 3.0 and Netscape are competing next generations of HTML 2.0. Proposed features in HTML 3.0 include: forms, style sheets, mathematical markup, and text flow around figures. For more detailed information, see the HTML Reference Manual. HTML is an application of the Standard Generalized Markup Language (SGML ISO-8879), an international standard approved in 1986, which specifies a formal meta-language for defining document markup systems (more here and here). An SGML Document Type Definition (DTD) specifies valid tag element names and attributes. HTML consists of embedded content separated by hierarchical case sensitive start and end tag names which may contain embedded element attributes in the start tag. These attributes may be required, optional, or empty. In addition, documents can be inter or intra linked by establishing source and target anchor points. Many HTML documents are the result of manual authoring or word processing HTML converters, but now several WYSIWYG HTML editors support styles – see listing at W3C and the Internet Survey Tools section on HTML authoring. HTML files are viewed using a WWW browser client (software), the primary user interface to the Web. HTML allows for embedding of images, sounds, video streams, form fields and simple text formatting. References, called hyperlinks, to other objects are embedded using URLs (see below). When an object is selected by a hyperlink, the browser takes an action based on the URL’s type, eg, retrieve a file, connect to another Web site and display a HTML file stored there, or launch an application such as an E-mail or newsgroup reader. Universal Resource Identifier (URI) – an IETF protocol for addressing objects in the WWW ( “if it’s out there, we can point at it”). There are two types of URIs, Universal Resource Names (URN) and the Universal Resource Locators (URLs). The current IETF URI spec is here and the URL spec is here. URLs are dependent arrivals and contain four distinct parts: the protocol type, the machine name, the directory path and the file name. There are several kinds of URLs: file URLs, URLs FTP, Gopher URLs, News URLs, and HTTP URLs. URLs may be relative to a directory or offsets into a document. Arguments to CGI programs (see below) may be embedded in URLs after the? Character. Hypertext Transfer Protocol (HTTP) – an application-level network protocol for the WWW. Tim Burners-Lee, father of the Web, describes it as a “generic stateless object-oriented protocol.” Stateless means neither the client nor the server store information about the state of the other side of an ongoing connection. Statelessness is a scalability property but is not necessarily efficient since HTTP sets up a new connection for each request, which is not desirable for situations requiring sessions or transactions. In HTTP commands (request methods) can be associated with particular types of network objects (files, documents, network services). Commands are provided for establishing a TCP / IP connection to a WWW server, sending a request to the server (containing a method to be applied to a specific network object identified by the object’s identification, and the HTTP protocol version, followed by information encoded in a header style) returning a response from the server to the client (consisting of three parts: a status line, a response header, and response data), and closing the connection. HTTP supports dynamic data representation through client-server negotiation. The requesting customer specifies it can accept certain MIME content types (more on this below) and the server responds with one of these. All WWW clients can handle text / plain and text / html. HTTP/1.0 Internet Draft 05 (the seventh release of HTTP/1.0) is targeted as an Internet Informational RFC. The next immediate version of HTTP is HTTP/1.1 Internet Draft 01.

It is not a definitive complete explanation, but it tries to enumerate the architectural decisions, which have been made, show how they are related, and give references to more detailed material for those interested. Necessarily, from 50000 feet, large things seem to get a small mention. It is architecture, then, in the sense of how things hopefully will fit together. I have resisted the urge, and requests, to try to write an architecture for a long time: This was from a feeling that a dead and therefore less valuable document must any attempt to select which, of all the living ideas, seem most stable, logically connected and essential. So we should recognize that while it might be slowly changing, this is also a living document. The document is written for those who are technically aware or intend soon to be, so it sparse and heavy on explanation in terms of terms.
