SQL Construction Kit aims to provide a simple builder/factory pattern based approach to generating DML SQL for all popular RDBMS systems. Included builders are SelectBuilder, InsertBuilder, UpdateBuilder, and DeleteBuilder. It is much lighter weight than any of the ORM tools available, and is 100% Java. It is a complete re-factoring of code that has been in production use since 2001 (updated to use features of Java 6). Also included is a Facade patterned Database object that wraps a Datasource object. This provides an execution framework for the results of the Builder objects, which includes simplified transaction and batch management as well as the ability to transparently handle SQL exceptions in a default manner. The Database object also provides a simple object-oriented approach via wrappers around the database metadata.
Membase is a distributed key-value database management system, optimized for storing data behind interactive Web applications. Membase automatically spreads data and I/O across servers. This "scale out" approach at the data layer permits virtually unlimited growth of transaction capacity, with linear increases in cost and constant per-operation performance. Membase is in production behind thousands of applications, from shared-server deployments at Heroku to dedicated Membase clusters with hundreds of servers at Zynga and NHN.
The Data Mine is a search engine designed to make a more useful interface available to users. It is designed around human-computer intelligent interaction considerations. It divides the screen into two halves. One lets you find all the instances of your query's keywords, and the other lets you look through a highlighted version of the results you choose.
Pronto is a framework consisting of loosely-coupled layers designed to handle the mundane elements of Web development without sacrificing the developer's overall control of the project. It is a PHP4/PHP5 MVC framework that supports robust dispatching, CRUD scaffolding, transparent data caching, i18n, flexible ACLs, and much more.
utf8proc is a library for processing UTF-8 encoded Unicode strings. Some features are Unicode normalization, stripping of default ignorable characters, case folding, and detection of grapheme cluster boundaries. The library can be used in C programs, but most of the functionality is also available as a ruby library. For PostgreSQL, there is an extension providing a function for preparing strings in case insensitive indices. The currently supported Unicode version is 5.0.0.
TM++ is an embedded, portable, persistent Topic Maps engine. It is designed to work according to the ISO standards for TMDM 1.0 and XTM 1.0/2.0 on Windows and most POSIX-compliant operating systems like Unix and Linux. It has interfaces for C++, ALLEGROCL, CHICKEN, CLISP, CFFI, C#, Guile, Java, Lua, Modula 3, Mzscheme, Ocaml, Octave, Perl, PHP4, PHP5, Pike, Python, R (aka GNU S), Ruby, Lisp S-Expressions, Tcl, Common Lisp/UFFI, and XML.
