Dive into Expression Trees


I am in the process of developing a framework for sampling query results from LINQ queries. It is going to be hard work, you may ask WTF in this world someone need sampling query results from LINQ queries? Well, this can be particularly useful if you are developing a new database that purely works with LINQ or you are having heavy data services that use various data sources then you want to sample the query result.

Unfortunately, I am not currently working on any core database system or heavy duty data services (at work), but I have to do this as part of my study. This project which is going to be an open source project called [I don’t know yet] is supposed to do the job of evaluating my algorithms that I hopefully (fingers crossed) will publish at VLDB 2011.

So if you continue to visit this blog, you will see posts about these topics:

  • LINQ Expression Trees
  • Writing Provider for LINQ
  • Sampling Techniques
  • Data quality metrics
  • and, Rule based profiling
