Visualizing Data Paging for Flex with 2 million database records

In my previous post I shared an example showing data paging for flex. The most important subfeatures of our ‘managed data paging’ feature are:

1. Loosely coupled interface – the feature will work without implementing a specific server-side interface and can be used with Java,  .NET and PHP
2. Can be used with ANY Flex data component (applicable to both MX and Spark architectures)
3. Memory management – our data provider will maintain only specific number of pages in memory and will re-fetch data on as needed basis

We put together another example visualizing how memory management work. The example works with a database table containing 2.6 million records. Any time a page of data is loaded or removed from memory, the visualization component reflects it by drawing or removing a line. You can see the example in action in the video below. The source code and the database script are available at the bottom of the post. Enjoy!
