Systems and Prototypes


The ATLaS System

http://wis.cs.ucla.edu/atlas/

ATLaS is a unified solution to a large variety of problems in decision support applications including:

  • SQL extensions for more complex OLAP queries;
  • new datablades for special data types such as time-series;
  • architectural extensions to support data mining functions
  • Support for data streams.

ATLaS is based on User-Defined Aggregates (UDAs) and table functions expressed in an SQL-like language. ATLaS is an extension of the AXL system.

LDL++

The Logical Data Language LDL supports advanced queries and reasoning on databases, including the internal database managed by the LDL++ system, and external SQL-compliant databases. The Java interface allows a user to access LDL++ agents on the internet and to create advanced applications on remote databases.

  • To run LDL++ 5.1 through command line, run as "/u/class/cs249cz/ldl++/LDL++5.1" through CS account, as described here.
