The ATK Framework is a PHP business framework. It is targeted at developers who wish to focus on business logic instead of coding HTML. ATK provides a complete framework that requires only small amounts of code to get usable applications, while maintaining full flexibility. ATK has a model driven approach, but is 100% customizable.
jPersist is an extremely powerful object-relational database persistence API that manages to avoid the need for configuration and annotation; mapping is automatic (A-O/RM). It uses JDBC, and can work with any relational database and any type of connection resource. It uses information obtained from the database to handle mapping between the database and Java objects, so mapping configuration is not needed, and annotation is not needed. In fact, there is no configuration needed at all.
Schevo is a next-generation DBMS that focuses on database integrity, rapid development, user interface generation, rich schema definition, and assisted schema evolution. Schevo was designed to address shortcomings in SQL-based relational databases where they do not match well with object-oriented programming languages. Schevo solves this problem by combining relational features with the object-oriented programming language Python. Schevo includes a GUI Navigator that can display a fully interactive interface into any Schevo database, using the metadata available within a Schevo database file.
php_db2util is a module that extends PHP with mass data movement functions. It supports connecting to a DB2 server, loading data from a client or server with a replace option or insert option, and exporting data from a table to a client. It also allows the runstats utility to be run to recreate indexes.
SPL is a powerful scripting language. It features hashes, regular expressions, objects, exceptions, a built-in template language, and has a C-style syntax. It can be used stand-alone or embedded in other applications. The entire SPL toolchain (compiler, assembler, virtual machine, etc.) is pretty small (about 100k on x86 architectures). One of the more advanced VM features is the capability to dump the entire VM state to a file and resume later. It even is possible to resume on another machine with a different architecture.
