HTSQL -- A Query Language for the Accidental Programmer

HTSQL ("Hyper Text Structured Query Language") is a high-level query language for relational databases. The target audience for HTSQL is the accidental programmer -- one who is not a SQL expert, yet needs a usable, comprehensive query tool for data access and reporting.

HTSQL is also a web service which takes a request via HTTP, translates it into a SQL query, executes the query against a relational database, and returns the results in a format requested by the user agent (JSON, CSV, HTML, etc.).

Use of HTSQL with open source databases (PostgreSQL, MySQL, SQLite) is royalty free under BSD-style conditions. Use of HTSQL with proprietary database systems (Oracle, Microsoft SQL) requires a commercial license. See LICENSE for details.

For installation instructions, see INSTALL. For list of new features in this release, see NEWS. HTSQL documentation is in the doc directory.
