                               AQUAdexIM
This is the source code package of AQUAdexIM, which provides a novel indexing and
retrieving method for astronomy image data.

In this program, three methods are implemented and their overheads and query
performances are tested. "Direct Query" method does not take advantage of
pseudo-sphere indexing and is used as a baseline. "AQUAdexIM" is our in-memory
index implementation. "Redis Query" utilizes the widely-adopted NoSQL database
and it is a fair performance competitor as both AQUAdexIM and Redis run in the
main memory. Experiments results have shown that AUQAdexIM is up to 10X faster
than Redis in querying astronomy image data.

This program has the following dependencies:
  - postgresql-9.4 (PostgreSQL relational database)
