What is OAT?
What is Ajax?
What are the benefits of Ajax?
- The ability to leverage the same interface technology no matter whether you're dealing with local or remote sites or applications.
- The ability to build standard interfaces independent of client browser, OS, and other variables.
- Using AJAX leads to deploying service-oriented enterprise applications much easier, avoiding platform localization and testing issues.
- The ability to leverage Web services using a more dynamic and rich interface than traditional browser technology.
- The ability to quickly create mash-ups to solve specific business problems using standard dynamic interfaces that front services.
What is the relationship between Ajax and Rich Internet Applications?
Rich Internet Applications (RIAs) are web applications that offer the responsiveness, "rich" features and functionality approaching that of desktop applications. Early Internet applications supported only a basic HTML graphical user interface (GUI). Though they could serve simple functions, these applications did not have the look or feel of a desktop application. The relatively slow Internet connections these applications relied on led to the term "World Wide Wait." RIAs are a result of today's more advanced technologies that allow greater responsiveness and advanced GUIs. On the other sight, AJAX allows partial page updatesmeaning updates of individual pieces of a web page without having to reload the entire page. This creates a more responsive GUI, allowing users to continue interacting with the page as the server processes requests. Additionally, Ajax performs a vital role in Web 2.0, particularly in building Web-top applications and enhancing the user's overall experience.
What are the benefits of OAT?
- Easy to use and include in different applications
- Offers rich list of complete widgets
- Offers rich list of supplemental widgets
- Includes libraries such as JSON, Cryptography, Statistics, etc.
- Easy to use Ajax DB Connectivity
- Includes a number of standalone applications for SPARQL, RDF data processing, etc.
Who is the target audience for OAT?
All application developers.
Can OAT be used in conjunction with other Frameworks?
One example is the Virtuoso ODS Framework
What Browsers are compatible with OAT?
OAT works in Gecko browsers (Firefox, Mozilla/SeaMonkey), IE6/7, Opera and Apple WebKit.
How is OAT Licensed?
OAT is licensed under the GNU General Public License.
Note that the only valid version of the GPL license as far as this project is concerned is the original GNU General Public License Version 2, dated June 1991.
UI Widgets and Controls
The OAT UI Widgets and Controls are divided into 2 sections:
- complete widgets
- supplemental widgets
What are OAT Controls?
Why are they important?
How do I use them?
Are there any usage samples?
Yes. You can check our online documentation.
Data Access Framework
What is Ajax Database Connectivity?
XMLA is the SOAP or REST protocol used for SQL Data Access (as per the above). SPARQL, GData, and Web Services (REST and SOAP) are the wire protocols for the respective query mechanisms.
Why is it important?
What Data Source formats are supported?
How is Database Independence Achieved?
How do I bind data from supported data sources to Ajax controls?
