Screencast: Yahoo! Maps variation of Ajax Database Connectivity Maps Mash-up

This is a Yahoo! maps variation of the Google Maps based Forms Designer mash-up screencast.

Screencast: Building Database Centric Web 2.0 Mash-ups using Ajax Database Connectivity

Fri, 26 May 2006 22:38:00 GMT

This screencast covers the actual codeless process of building a database centric Web 2.0 mash-up using OAT's database-aware Forms Designer. This is basically the simplicity of Paradox or Microsoft ACCESS form building delivered via Ajax without any database or operating system lock-in. This demo uses the Google Mapping Service (note: there is a Yahoo! Mapping Service screencast demo that follows this post). Also note that fact that in this demonstration I actually incorporate the Pivot building functionality from an earlier Ajax based Pivot Building screencast.

Screencast: Using a Live Report (mash-up) that exploits AJAX Database Connectivity

Another demo. This time around you are looking at a quick and dirty mashup assembled using the OAT FormDesigner. There is a follow-on demo that shows how this was assembled (no coding whatsoever!).

Screencast: Ajax Database Connectivity and SQL Query By Example

Fri, 26 May 2006 21:59:00 GMT

AJAX Database Connectivity is the Data Access Component of OAT (OpenLink AJAX Toolkit). It's basically an XML for Analysis (XMLA) client that enables the development and deployment of database independent Rich Internet Applications (RIAs). Thus, you can now develop database centric AJAX applications without lock-in at the Operating System, Database Connectivity mechanism (ODBC, JDBC, OLEDB, ADO.NET), or back-end Database levels.

XMLA has been around for a long time. Its fundamental goal was to provide Web Applications with Tabular and Multi-dimensional data access before it fell off the radar (a story too long to tell in this post).

AJAX Database connectivity only requires your target DBMS to be XMLA (direct), ODBC, JDBC, OLEDB, or ADO.NET accessible.

I have attached a Query By Example (QBE) screencast movie enclosure to this post (should you be reading this post Web 1.0 style). The demo shows how Paradox-, Quattro Pro-, Access-, and MS Query-like user friendly querying is achieved using AJAX Database Connect Connectivity

A Web 2.0 Style Mash-up using the OpenLink Ajax Toolkit (OAT)

Thu, 25 May 2006 20:47:00 GMT

We are now on the verge of finally releasing one of the many items discussed in my recent chat with Jon Udell. The item in question is the OpenLink Ajax Toolkit (OAT) that enables the rapid development of Database Independent Rich Internet Applications. My very first public screencast is deliberately silent (since its a live work in progress etc.).

The screencast style demo covers the production of a map based mashup that simply unveils the national flag of each country underneath its map marker (a lookup associated with geocoded map pin).

This post is also a deliberate test of the automatic production of IPod and Yahoo RSS sytle syndication gems based on the content of my blog post. Naturally, this is a demonstration of the soon to be unveiled OpenLink Data Spaces technology (the one that supports GData and SPARQL Query Services).

BTW - The the Data Space that is this blog has been GData aware for a few weeks now (I digress, just watch the movie!):

Note: If you are reading this post Web 1.0 style (i.e. via traditional non aggregating browser UI) then click on the "enclosure" link to grab the quicktime movie file. If on the other hand your are reading via a Web 2.0 aggregator, note that the Podcast Gem should alert you to the existence of the movie enclosure.

Building Pivot Tables using Ajax Database Connectivity

Fri, 26 May 2006 22:08:00 GMT

This screencast demo (enclosure attached) is a continuation from my earlier Ajax and QBE screencast demo. This time the focus is on building Excel like Pivot tables using data exposed via Ajax Database Connectivity.
