How To Keep Web Development Costs Low
Most web development projects include one or more of the following elements...
Each of these elements has to work in its own right, and in cooperation with the other elements. The more complex the project, the harder it is to bring it all together and make it work correctly. How to keep the cost down Here's how you can make sure your web development costs don't run over budget...
The key to achieving the second of these two items lies with the first. You should insist that an Agreement document be created, and sit in on the process. You need both end-users and developers in the same room, working through each aspect of the development. The end result must be a document that fully describes the development, is clear (unambiguous), and easily understood by both users and programmers. Every minute you invest creating this document greatly increases your chance of bringing the project in on budget. Why it's worth it Many of the problems that usually cause headaches during a complex development could have been discovered in advance, if an Agreement document had been created. When users and programmers get together and discuss their respective needs thoroughly, the resulting development is far more likely to go smoothly. This kind of interaction forces both users and programmers to think through what's actually required to make the system work. The ongoing interaction reduces the risk that person A assumes person B knows what they're talking about. Users are committing to a specific set of functions for an agreed price. The developer is committing to develop those functions for an agreed price. This means both users and developers have a self-interest in being thorough. Should a user change his/her mind about something after the Agreement document is signed, the cost of development must be renegotiated. This punishes the user for failing to think things through. Should the developer discover he/she hasn't fully understood what's required to complete some aspect of the project, he/she can't ask for more money. This punishes the developer for failing to break down each stage of the development and understand what's involved in completing it. Assuming you do your part, you won't need to make changes after the work has started. As a result, you'll bring the project in on budget even if the developer hasn't done his/her job properly.
Semantic Web
Introduction Semantic web as defined by the creator of the web Tim Berners-Lee is "a web of data, in some ways like a global database" (Berners-Lee, 1998). To elaborate further Mr. Berners-Lee explains in an interview held by IDG Now, data is expressed on computers as associated files with applications that deal specifically with information, an example would be, data in calendars, bank systems, spreadsheets, and database application. Looking at a web page, data is not clearly defined and not associated with any of the applications usually on computers. Semantic web will allow data to interact and connect together; it will bring on a common data format for all applications, for databases and web pages alike (Moon, 1999). Semantic web is not to build an artificial intelligence system which allows computers to understand what humans write on web pages; on the contrary, it is an attempt to make web pages more understandable and well-defined to support automatic extraction of data from within web content (Berners-Lee, 1998). Analysis The emergence of the web and the way HTML took off was driven by how society's needed to grew, from Internet chat to file transfer to high-end communities through blogs and wiki's. HTML was not limited to web content, knowledge base and help files adapted the language as a format to document software applications and provide training material. The revolution of technologies on the Internet allowed companies like Google to index pages; a thought that was very far away, says Tim Berners-Lee in his lecture at MIT. Web services have evolved to pave the road for distributed information and modular programming allowing interoperability among sites. Through XML, data in one site can be used by another using the common protocols and standards supported by both (Berners-Lee, 1998). XML defines schemas that deal with fields of data, what is required is a system that can tell the computer what sort of information (data) it can derive from within a page (Moon, 1999). With Web 3.0 a site will provide data that can be navigated through and extracted from multiple sites, this is a result of the fact that semantic web data model is closely related to a relational database where records of data share common fields that connect them together (Berners-Lee, 1998). The solution provided to support semantic web is in the form of metadata that describes the data contained on web pages. Resource Description Framework (RDF) is a base to manage metadata; it is the ground that computers can use to exchange and interact with applications on the Web (W3C RFC, 1999). The applications for RDF include digital libraries, online catalogs, and indexing systems that are usually associated with content and content relationships models deployed in most web pages. With RDF data within business portals will be analyzed and identified as resources, properties, or statements transparent to the domain, further more, the specifications will merge with other documents to comprise a framework of classes. Classes organized as a hierarchy comprises a schema that can be reusable as metadata definitions along side multiple platforms. Resources created in this hierarchy can be identified using a resource identifier (URI), which enables a document given to a machine with this identification to be recognized by the system and triggers it to dig and find similar data (Berners-Lee, 1998). Implications Semantic web can be the solution to overpower the limitations of current information management systems in finding and extracting data from unorganized resources. RDF is meant to describe any data regardless of its character, location, source, or type, the concept of URI is richer to uniquely identify any object on the web (Berners-Lee, 1998). The pillars of Semantic web are standards and common protocols that are the bases for knowledge representation; HTML, RDF, the data language resource description web ontology language (OWL) that describes to the machine what is going on, in addition to RDF1 which is a query language to make inquiries among machines much easer, will all emerge and collaborate to bring in more to the web and more intelligent programs that will bring the Internet more closer (Cleave, 2004). The current research and implementation of Abilene network and the Next Generation Internet (NGI) Internet 2 of high-performance backbone network linking major universities and research labs across the US, is a good foundation for what Semantic web can do, and represent the perfect platform for grid computing, digital libraries, virtual laboratories, and distance learning (Abilene, Internet2). Internet2 or I2 was developed by a group of universities in 1996 providing improved connectivity standards to reach 10gbps (gigabits per second). With more than 227 universities and libraries connected, network based applications and experimental programs can run on this network of high-bandwidth connection feeding on the latest technology of gigabit Ethernet and IP protocol version 6 (Reardon, 2004). Semantic web standards can be the base of material and data distributed on this network, providing the best test platform to explore the full potential and what can be achieved. Conclusion Tim Berners-Lee believes that with Web 3.0 we can succeed and fantastic things can happen, but the infrastructure need to be built, laws of privacy and security need to be revised and honored, further more, the web need to remain open for researchers to allow for continuous upgrade and development. Semantic web will kick off when individuals materialize the need to work on data processing, and think about collaborating their data, with company's information and that of the government (Moon, 1999).

E-Commerce Web Hosting Best Templates
Web design for a competitive business isn't easy, especially when you add e-commerce (the buzzword for buying and selling online) to the mix. Thankfully, many service providers have basic web hosting templates available to their customers at little to no cost depending on your package. More complex templates can be quite expensive. Companies that provide hosting with templates make setting up and maintaining an e-commerce website possible for people without the expertise to do it themselves and without the money to hire a professional to design their site from the ground up. When purchased separately from your web hosting package, a template can run anywhere from $20 for a basic, simple web template and well into the hundreds of dollars for a more complex, custom design. For the majority of small business owners, basic templates designed for businesses are usually a safe bet. An e-commerce template may include basic pages, search and navigation tools such as a virtual shopping cart, but it will be up to you to find your own online payment processing - most often through a third party provider such as PayPal. A web search for "online payment processing" will provide you with several options. As an alternative, you might want to consider a turnkey solution such as eBay Stores or Yahoo! The designs of sites like these make e-commerce solutions for small business accessible to everyone. Be sure to read the find print about transaction fees and other costs before you decide. Questions to Ask about Functionality 1. Does the shopping cart accept debit cards and online checks? Questions to Ask about Cost 1. What are the basic monthly fees? Talk to other business owners about their choices and do your homework. The right solution is out there for you, you just have to be willing to do what it takes to find it!
