beancounter enables stockmarket data analysis and performance evaluation. It has two main modes. The first is data gathering - both current data (e.g. closing prices, high, low, volume etc.) and historical price data can be retrieved efficiently using multiple securities per requests, and stored in an SQL database (PostgreSQL, MySQL, and SQLite are supported) via easy command line operations. The second mode is data analysis, based on the previously stored data. This comprises various performance reports, as well as a Value-at-Risk analysis. beancounter is implemented as a Perl module, and a Perl command-line frontend to the module. It supports different stock markets from around the globe, foreign exchange rates, US mutual funds, and US options.
CodeBase is a high-speed xBASE compatible database engine for C/C++, Visual Basic, Delphi & Java programmers. You can use CodeBase to write high performance database applications that are multi-user compatible with FoxPro, dBASE and Clipper, create anything from a Java applet to a full-blown Windows database application to a simple DOS utility, write scalable applications that can be deployed as single-user, multi-user or client/server, all without changing any of your source code, and port your applications to Windows, DOS, UNIX, OS/2, and Macintosh. There's a free 30-Day Test Drive option available. CodeBase is available for every major operating system including Windows XP, 2000, 9x, NT, CE, DOS, OS/2, Macintosh, and a variety of Linux and UNIX platforms including Solaris, SunOS, HP/UX, AIX, SCO, and others.
The DataBrowser is a Java-based tool for browsing virtually any database. It has been tested with Oracle, SQL Server, PostgreSQL/Postgres, MySQL, DB2, and MS Access (among some others). It requires a Java 2 runtime environment. The DataBrowser allows you to execute dynamic SQL, import and export data, view the schema in a treeview, and view query results in a table view. It also logs all SQL executed with the SQLLog feature.
GQL is a C++ library for generic SQL database access, modeled after JDBC (Java Database Connectivity). It includes drivers for PostgreSQL, MySQL, and SQLite, and includes GQL-Shell, an interactive database terminal called that features command-line editing, history, and database metadata (schema) browsing.
