ColdFusion is a program based on the CFMX programming language that builds and deploys powerful web applications and services. With proven tag-based methodology, ColdFusion’s features allow web developers to easily harness the power of the Java Platform to deliver powerful Internet applications to millions of people worldwide. ColdFusion is a server side language, which is executed by a ColdFusion application server. It works by executing CFM templates (which is a mixture of HTML and ColdFusion instructions) to return normal HTML to the requesting browser. The ColdFusion MX Enterprise software suite provides all the necessary software to create large-scale websites, applications, and hosting environments, and is available for either a stand-alone installation for web developers or for industry-level deployment on J2EE application servers. - The true power of ColdFusion Markup Language (CFML)
The core functionality of ColdFusion Markup Language (CFML) is centered on the use of tags. These server scripting tags give ColdFusion its speedy development applications for the web. CFML is quite simple to learn, but is powerful enough to handle even the most complex and demanding web applications. Processed entirely on the server, CFML uses syntax closely resembling that of HTML and XML. CFML consists of two primary language elements: tags and functions. Tags let you perform operations such as accessing a database. Functions can return data and do other operations like retrieving the system date. Tags, functions and operators make up expressions. Building expressions in ColdFusion is easy and can include simple as well as complex elements. The ways in which these expressions and elements are used determine how ColdFusion processes your program. - Is ColdFusion easy to learn?
Out of the many different methods used to develop and build web applications, pages, and services, ColdFusion is by far the easiest to learn and use. For ColdFusion 7.0, Macromedia has created a helpful ‘Getting Started Experience’ interface that gives the new user access to tutorials, whitepapers, topic index, and even two sample applications to play with. There is no other language or product as well suited to web developers as ColdFusion. Easy-to-use visual tools and an intuitive server scripting environment allow new users to easily pick up the CFML language. - Windows, UNIX, or Linux…which Should I Use To Run My Website?
Macromedia ColdFusion MX supports most operating systems including Windows, Unix, Linux, IBM AIX and HP-UX. Below is a list of operating system versions and system requirements for the latest ColdFusion version: Windows OS Intel Pentium processor or higher 256 MB RAM but 512 MB is highly recommended 400 MB of hard disk space available Works on MS Windows 98 / ME / NT 4 / SP6A / 2000 /SP3 / XP/ 2003 Linux OS Intel Pentium processor or higher 256 MB RAM but 512 MB is highly recommended 400 MB of hard disk space available Red Hat Linux 7.2 / 7.3 / 8.0 / 9 / AS & ES 2.1 / AS & ES 3.0 SuSE Linux 7.2 / 7.3 / or 8X Turbo Linux 8 Server ( Japanese Only) Unix SPARC, PA-RISC 1.1 / 2.0 / Power 3 processor Sun Solaris 7 / 8 / 9 256 MB RAM but 512 MB is highly recommended 400 MB of hard disk space available HP-UX 11i IBM AIX 5L 4.3 / 3 / 5.1 / 5.2 Apple Mac OS X - What Databases and Web Servers are supported with ColdFusion?
ColdFusion MX supports most major databases including Microsoft SQL, Microsoft SQL Server, Oracle, IBM DB2, Sybase and IBM Informix. In addition, CFMX can run on most major web servers including IIS, Apache and Sun One. - What are the differences between the ColdFusion 7.0 editions?
Standard Edition: This edition is for single web application or small workgroup environments. It builds accessible, high-quality rich forms, transforms existing HTML content into PDF or FlashPaper 2 formats, creates structured business reports for workgroup applications, delivers charts and graphs, and increases text searching capabilities. Enterprise Edition: This edition is ideal for the quickly growing business. It includes all the features of the Standard Edition as well as scalability, performance, and enterprise management capabilities for larger web and business applications. The Enterprise Edition has multi-instance deployment and management, clustering, high-speed enterprise database drivers, server security J2EE packaging and deployment, and high-performance e-mail delivery. Yet the most anticipated feature of this edition is the event gateway, which enables ColdFusion applications to connect to mobile phones and instant messaging. - How does ColdFusion run on application servers?
The ColdFusion MX runtime environment is actually a Java application that takes advantage of the many powerful services in the J2EE platform. What this J2EE platform does is connects the various databases, manages its own security, as well as processes the requests sent in by the application itself. When ColdFusion MX is installed in the J2EE configuration, the compiled infrastructure will be on top of the application server in order to execute the language’s applications. This configuration will allow developers to cultivate and set out pages, as well as manage the MX server settings using the ColdFusion Administrator. - What are the advantages & disadvantages of using custom tags in ColdFusion?
Using custom tags within ColdFusion has its advantages and disadvantages. Custom tags written in CFML primarily try to achieve a simple balance between three aspects; taking argument statements, having body tags begin and end with the appropriate tag, and ensuring proper processing when a beginning tag is encountered by the ColdFusion program. If designed properly, these custom tags will also be able to be called recursively (meaning that it will have the functionality to call itself within the body tag). Although a custom tag in ColdFusion will call a page included the CFinclude tag, the disadvantage is that the code must be recursive, have developed complex functionality, and must be convenient for others (although often times code is not convenient). If creating either a User Defined Function (UDF) or a custom CFML tag, weigh the options carefully, since invoking a UDF requires less system overhead than using a custom tag. - What are the new features for ColdFusion 7.0?
ColdFusion 7.0 brings a whole new level of features to developers. With better web application creation, new server management and deployment options, and a new class of applications, users are able to quickly create powerful Internet applications without spending a lot of time or money. Macromedia developed the new features to help web developers be more efficient in performing routine tasks such as structured business reporting, Flash-rich forms, and PDF and FlashPaper 2 document generation. ColdFusion Report Builder, a tool that helps users develop detailed business reports, will create sub reports, charts and graphs, automatically generate subtotals, and much more. ColdFusion 7.0 simplifies the form building process with the new Rich Flash and XML Forms capabilities. The new CFDOCUMENT feature eliminates chopping page printing with a single tag that transforms web pages into PDF or FlashPaper 2 formats. - How do I purchase my own copy of ColdFusion?
The ColdFusion MX suite is available directly from Macromedia, local computer software resellers, licensing programs and some web hosts. | | |
| Real Host Vs. Reseller Host - How Do You Know? In today’s world of web hosting, there is literally a deluge of companies from which you can purchase hosting services. These hosts can offer a multitude of packages at a variety of prices. But how can you tell when you are purchasing services from an actual hosting provider, or from a reseller? Better yet, when and how will this knowledge make a difference? Let’s first start with what the difference between a hosting provider and a reseller is. An actual web host provider is selling services from servers that it owns and maintains. Typically, they manage the machines, networks, DNS, and the actual uplinks to the Internet backbone. When you call a true hosting provider for support, they handle it directly. A reseller, on the other hand, is merely a merchant who sells the services provided by the actual provider. This is not to say that the reseller does or cannot offer their own services, like web design services for example, in addition to the hosting services. Resellers do not own the servers, or manage the network, or any of the truly technical stuff that the actual provider does. When you call a reseller for support issues, most of the technical problems are relayed to the actual host. In essence, the reseller functions in a similar fashion as a retailer, reselling goods provided by someone else at a profit. Now, the question to ask yourself, is how does this affect you? Truth is, in most cases, it doesn’t matter. So long as you are getting the services you need, at a price you are happy with, why would it matter if you were getting it directly from the provider or from a reseller? Too bad it can’t always be that simple. If you have a high traffic website, or if you wish to purchase a dedicated or co-location account, it may be worth your while to ensure that you are working with an actual hosting provider. This ensures that your account can receive the highest level of attention possible, since all agreements and issues are addressed directly with the people who are responsible for the work, instead of thru intermediaries who may or may not communicate your needs effectively. Now, this is not always the case. Some hosting resellers are well equipped to handle even the most demanding of needs. But overall, for those with an overpowering need for the highest quality relationship, working directly with a hosting provider is your best course of action. Now, the actual process of discovering whether or not your prospective web host is a reseller or an actual provider is not always as simple. Most resellers don’t come right out and tell you that they merely resell someone else’s offering. Here are a few ways that you might try if you need to determine for yourself. 1) Check the WHOIS directory 2) Visit a domain registrar, such as Network Solutions to see if the name servers of the hosts domains match their domain name. If they are different, chances are that they are a reseller. 3) Run a tracert – Tracert is a utility that will show a path of all computers that are hit in order to access a certain machine. The data returned by this utility can be a little confusing, so it is not suggested for beginners. 4) Visit hosting resources – There are many resources available on the Internet in regards to information about host providers. You can find reviews and information on many hosts in these places. Also help are site that have open discussion forums, such as http://forums.devshed.com/f12/s, where you can review information and even ask questions about specific hosts. 5) Call and ask – If all else fails, why not just contact the host and ask them directly. If for some reason, you cannot get a direct answer to the question, it is safe to assume that they are probably a reseller. In summation, there are a few methods you can use to determine whether a host is a reseller or not. Most owners of small to medium sized websites can get their needs met quite adequately by hosting providers and resellers alike. If you feel that it is essential to have your site hosted by the actual provider, or even if you are just curious to know for sure, it should be easy to determine the facts about any potential hosts by using the methods described above. | Click here to return... | |
