Tdbengine is an RDBMS with an integrated programming language. It represents the enhancement of the famous DOS-TDB, and is designed to handle databases on the Web. It connects to the Web server using the standard CGI interface, or runs on the command line. It is very small (about 400 KBytes), extremely quick, and easy to administrate. Its features are full text indexing, an automatic data link system, and the script language EASY, which replaces the commonly used SQL with its modular code.
Tntdb is a c++-class-library for database access. It implements a database-independent layer, which loads the actual driver dynamically when a connection is made. The classes use automatic resource management with reference counts. Resources are freed when the classes go out of scope. Error handling is done with exceptions (derived from std::exception). There are STL-like iterators for result sets and rows, and also the cursor is an STL-like iterator. It is written in standard C++ with Linux. Drivers for PostgreSQL, sqlite3, MySQL, and Oracle are available.
The trading shim is a command line interpreter with a DBMS backend to the socket-based 'binary format' API of the Interactive Brokers' Trader Workstation. It uses mnemonic ASCII text commands to permit downstream clients to easily access several worldwide securities markets and exchanges (stocks, options, futures, bonds, and Forex) for "tick" data and history (intraday and EoD). It also allows clients to initiate and supervise trades of securities, manage accounts, and more.
