Now stored at https://github.com/gregorydgraham/DBvolution Available from Maven Central: nz.co.gregs.dbvolution Makes relational data easy and fast to use with semantic annotations and encapsulated datatypes. Simple declaration of a DB table: @DBTableName("mytable") public class MyTable extends DBRow { @DBColumn("numeric_code") @DBForeignKey(Code.class) private DBNumber numericCode = new DBNumber(); @DBColumn("uid_mytable") @DBPrimaryKey @DBAutoIncrement private DBNumber uidMyTable = new DBNumber(); } Easy Gets: List<MyTable> myRows = myDB.get(new MyTable()); MyTable row = myDB.getDBTable(new MyTable()).getByPrimaryKey(61176904); Natural and Outer Joins and Criteria: CarCo carCo = new CarCo(); carCo.name.isLiterally("GM"); List<DBQueryRow> results = myDB.get(carCo, new Marque()); dbQuery.addOptional(new CarModel()); Easy debugging: query.getSQLForQuery(); Simple processing: db.print(query.getAllRows()); List<Marque> marques = query.getAll

JAAMS (Just Another Audio Management System) JAAMS is a JAVA library that organizes music using a relational database such as MySQL, or SQLite.

A complete, fast, previously commercial, JDO 1.0.1 implementation for databases, opened by Versant in 2005 and then abandoned in early 2006. The design-time code is already in Eclipse Dali. This project is the original source drop, including the runtime.

jPersist is an extremely powerful object-relational database persistence API that manages to avoid the need for configuration and annotation. jPersist uses JDBC and can work with any database supported by JDBC and any type of connection resource.

The Adept Library contains a lightweight Java Object database for stand-alone applications. It is designed for simplicity of use, exposing a simple DTO - no need for copy logic or complex serialisation techniques. It is also a powerful general library.

Beagle is a Java lightweight framework to fetch database entries in an optimized data structure.It can be useful in those application that need to a fast data access.It is designed around Agile Methodologies with pattern of Test Driven Development.

BuzzSQL is a thin layer over Java JDBC that manages automatic configuration of database connection setup, pooling, configuration, logging, and statement handling.

Catnap is a lightweight Java persistence layer which stores and retrieves objects from an Oracle database using PL/SQL packages.

ConStore is a light-weight model-oriented storage facility for concept networks (Concept-Nets) with seamless object-oriented programming interface. Concept-Nets can be viewed as arbitrary graphs where the vertices as concepts and the edges as Relations.

BioAcceso es un sistema para el control de asistencias de los empleados, tomando la huella dactilar del personal para su registro e identificación. Es una aplicacion de escritorio desarrollada con el lenguaje Java, utlizando Mysql Server como RDBMS.

A portable java IDE with support for syntax highlight, line numbers and others features. Version 0.2 is beeing prepared and will contain a lot of inovations and utilities.

Dynamic Dao is JDBC ORM framework. It allows to use annotations to attach SQL execution to interface methods.

Flexoodb stands for Flexible Object Oriented Database API. Using your choice of RDBMS, Flexoodb represents objects as XML, allows proprietary Serializable objects to be embedded within the XML representation and manipulation using extended classes.

By allowing you to simply and efficiently move data from Relational to Java Objects to XML and back again, Hydrate gives you the tools to merge, manipulate and report on data from your strategic and legacy reference data, and enterprise data warehouses.

Java Objects Persistence Service (JOPS) is a simple and very useful library dedicated to developers who don't need all the power of traditional DBs (MySQL,Oracle.etc) but still need to be able to persist and manipulate their persisted objects easily

JXmlSql is a Java database API ( MySql, Oracle, Access )that eliminates JDBC code. JXmlSql allows developers to define application and prepopulation SQL statements inside xml files. Options for query, insert, update, delete, report and prepopulation SQL.

JaQLib is a compact Java library that supports programmers in querying all sorts of collections, DBs and XML files in a compact and intuitive manner. Example: List<MyItem> result = Jaqlib.List.selectFrom(myCollection) .where(myCondition).asList()

MOFISP is (another) relational object mapper. The purpose is to create an object oriented view over legacy bases.

Java Object and Relation Persistence framework. No mapping configuration needed! Automatic mapping of object relations, inheritance, arrays ++. Also includes a DB-version migration framework. Powerful, yet easy to use.

MAOS (Meta-Attribute Object Store) is a light-weight Java library / framework implementing simple Object persistence using search-engine technology

MyBatis is a first class persistence framework with support for custom SQL, stored procedures and advanced mappings. MyBatis eliminates almost all of the JDBC code and manual setting of parameters and retrieval of results. MyBatis can use simple XML or Annotations for configuration and map primitives, Map interfaces and Java POJOs (Plain Old Java Objects) to database records. Every MyBatis application centers around an instance of SqlSessionFactory. A SqlSessionFactory instance can be acquired by using the SqlSessionFactoryBuilder. SqlSessionFactoryBuilder can build a SqlSessionFactory instance from an XML configuration file, or from a custom prepared instance of the Configuration class. Building a SqlSessionFactory instance from an XML file is very simple. It is recommended that you use a classpath resource for this configuration, but you could use any InputStream instance, including one created from a literal file path or a file:// URL.
