BUSH (Business Shell) combines the capabilities of BASH, PHP, GCC, and databases into a uniform design for rapidly building secure, reliable Web sites. Based on an ISO standard, it promotes code reuse: scripts and templates can be compiled with GCC or ported to JVM or .Net using third party tools with only minor changes. It can also replace BASH as an interactive command shell with SQL support, and is a general purpose scripting language.
DL/SQL is declarative, Turing-complete programming language based on top of a SQL database. The main idea is to store both program and data in one SQL table and make all the computations in it. The current version of interpreter written in PHP features quasi-lazy evaluation and simple caching.
