APLM (Alex Personal Library Manager) is a set of Perl scripts for managing a small library. It is designed to be easy to set up, easy to use, very customizable, and self-contained. It lets you type in your books, change a few paths, and get going without worrying about MySQL or anything. It also has a Web interface.
AbstractDB is a database abstraction layer, object oriented and extensible via driver implementations which extend from a common base class. This package encapsulates all of the basic functions required by most developers without the complexity and/or utter simplicity of many other abstraction packages.
AnyDBM is a Haskell module that provides a generic infrastructure for supporting storage of hash-like items with String-to-String mappings. It can be used for in-memory or on-disk storage. Two simple backend drivers are included with this package: one that is RAM-only, and one that is persistent and disk-backed. The hdbc-anydbm package provides another driver which lets you use simple tables in any SQL database to provide a DBM-like interface. MissingPy also provides a Python driver which lets you use any Python anydbm driver under Haskell AnyDBM.
Atris Framework is a fully functional platform independent GUI framework based on the Java/Swing API. It provides an advanced GUI screen editor with features including an abstract data layer, pre-built Design Patterns, data set to visual component mappings, window management (tiling, last position/size memory), database/app server login control, preference management, advanced table and tree management, advanced data relationship management, automated management of standard CRUD operations, launching GUI applications from Web sites directly, table sorting, column ordering, table searching, in-table editing, and the ability to import existing visual components in addition to many other features.
Aubit 4GL compiler is a programming language based on (and compatible with) Informix-4GL. It provides an easy way to generate screen/form based programs, since statements for handling Windows, Forms, Menus, SQL, and similar are built-in. With support for SQL statements forming an intrinsic part of the language, it's especially suitable for developing database-oriented applications. Database connectivity is provided for PostgreSQL, MySQL, Informix, and others via ODBC. It supports both ncurses (console mode) and GTK+ (GUI mode) output.
BeanKeeper is a full featured, powerful object/relational persistence and query library. It has a unique philosophy of simpleness and ease of use: it does not require config files, annotations, code generation, code "enhancing", or any kind of tools to be used. It handles simple Java beans (or POJOs) and its query service returns lists. Despite its simpleness, under the hood the library takes care of all the necessary logic: transaction visibility, result list paging, keys and ids, table creation/modification, class relations, inheritance/polymorphism, case sensitiveness, and much more. It currently supports: Oracle, HSQLDB, MySQL, and PostgreSQL.
