Functionality

There is a broad range of functionality in OAT including information visualization, GUI Widgets and Database Connectivity

Information Visualization

There are many different ways of visualizing data using OAT, these include:

File System Interaction

  • WebDAV Browser enables you to navigate a WebDAV instance as if it were a local filesystem.
  • An Upload Interface supporting batch uploads.

Graphical User Interface Widgets

There are many Widgets in OAT to ease development of application User Interfaces, including:

  • Combo Boxes, Combo Lists, Combo Buttons.
  • "Quickedit" -- simple editing without text-box input.
  • Sliders, Date Pickers and Color Pickers.
  • "Enhanced Anchors" enabling you to show a new widget on screen.
  • "Ghost drag" enabling the user to drag one item onto another and update objects accordingly. For example, this is quite useful for dragging items into a shopping cart.

Semantic Web and Aggregated Data Visualization

OAT is also able to cleanly visualize:

  • RDF Data as a graph.
  • RSS Feeds.

AJAX DataBase Connectivity

Provides a database independent data access layer for OAT and other JavaScript based libraries/frameworks/toolkits. The JavaScript equivalent of ODBC, JDBC, OLE DB, and ADO.NET, it uses XMLA to facilitate direct and platform independent access to remote database engines via XMLA providers.

As a core component of OAT, the Ajax Database Connectivity layer enables:

  • Development and usage of data bound controls such as the Google Maps, Yahoo! Maps, Microsoft Virtual Earth, and OpenLayers mapping services controls, Pivot Tables, Comb Boxes, TimeLines, and many more.
  • Development of data aware applications with the ability to calibrate change sensitivity via support for scrollable cursors (detached row-sets that are change sensitive)
  • Build a complex SQL, XML, SPARQL, Web Services based applications without exposure to data access complexity

Miscellaneous

Other controls include:
