The syntax for CONCAT () is as follows:CONCAT (String 1, String 2, String 3, ...)Concatenate string 1, String 2, String 3, and so on. Please note that Oracle's CONCAT () only allows two parameters, in other words, only two strings can be concatenated at a time. However, in Ora

consistent adoption of new Ajax standards (e.g. CCS, JavaScript, DOM ). the same can be said for Java: the Java Plug-in is provided by Sun Microsystems and provides a consistent presentation between SS browsers.
another area where Ajax really needs to advance is in terms of tooling. while there are some nice Ajax development tools coming out of vendors such as Microsoft, backbase, tibco, and nexaweb-the truth is Ajax ides are still pretty primitive
, there is still a considerable gap between the potential of Web Services and existing functions.
Enterprise Directors are willing to use Web services to meet simple requirements, such as sending information to Web-based portals. However, complicated key task transactions are another matter. They may need some Web service standards that are still under development. Therefore, when is it wise to choose an SOA strategy that uses Web Services? When is normal Enterprise Application Integration (EAI)
have been developed by the early workflow vendors, such as Staffware (now Tibco acquired); Some were developed by the early EAI providers, such as Tibco; Some are developed by Application server providers, such as Bea. There are many similarities in their BPM blueprints, such as the business Process described in the BPEL specification.
The second line is analyzed from domestic workflow applications and t

Zapthink, senior analyst Ronald Schmelzer, said: "Google has organized a large team of Ajax developers to develop Ajax services, but Google is a company with billions of dollars, so it has the ability to do so." ”
On the other hand, many companies are not able to hire such an AJAX dream team. And as long as Google needs to develop Ajax services it will be able to pay a large amount of money for
example, Iconix confidence Interval graphic--is used to display scanned gene expression data, which takes at least 2-3 seconds to load, because this scenario requires a dedicated graphical servlet to display each of the graphs individually. Examples of Drugmatrix confidence Interval graphic

He believes the application will be built with Ajax.
Kevin Hakman has been in the field of Ajax for a long time, and he is a founder of general interface. General interface is a rich Internet application development tool provider, acquired by Tibco Software company a year ago. Hakman is now Tibco in charge of the product market, and believes that the future of Web

Two months ago, at the invitation of the editor of the silver bullet magazine, he wrote an article on "process" and "microkernel, the title is "microkernel process engine design ideas and architecture ". Now the seventh issue of panyuan magazine has been published, and the full text is now transferred to my blog.

deployed SOA object based on Web Services must be divided into two stages. The central task in these two phases is to identify the service, and these services must be:
Developed using the new execution environment: requires the development of new application logic in the form of Java classes and ejbs to run in the WebLogic application server container.
To support existing application logic: you must use a tool set that is suitable for existing technologies and supports Web Services.
component technology provides clear support for SOA construction and is based on industry-recognized standards, the above two factors impede the implementation of reuse at the enterprise level. Note that the actual situation is even worse, because to use these standards-based technologies, enterprises need to make the system based on specialized middleware technologies, such as MQ and tibco. All these systems, whether based on standards or specialize

Use the Java Server Pages (JSP) model when data is passed to the JSP pageWhile this scenario is fairly good, the development team finds that the number of data to be displayed on the page is too large, which can discourage users from using interest. In addition, in terms of efficiency, the exchange and transfer of graphic data is particularly slow. For example, Iconix confidence Interval graphic--is used to display scanned gene expression data, which takes at least
