AVLMAP is a key:data pair data mapping (associative array) library for C programming based on AVL balanced binary trees. Added features include ordered data retrieval forward or reverse, support for optional duplicate keys (e.g. an extra linked list not needed), and the ability to find the nearest member if an exact match isn't available. Both key and data types may be selected from a choice of C data types including string and array variations. One mapping always has one key type, but data types may be mixed within a mapping.

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.
