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
...This is just the base of the framework presenting the idea, any code template can be implemented upon request.
Some sample generators are present for SQL / PLSQL / C# / AnsiC / Java
The main target is to generate DTO/BDO/POJO objects based on the database definitions in multiple languages aligning all technologies used by a development team.
If you are willing to contribute drop a message.
ChronoDB is a data manager for generic time series.
...With its simple and powerful schema subsystem it takes charge of very large heterogeneous data sets. The software consist of an API and a generic implementation layer running on top of an SQL or a NoSQL system. Applications can mix objects from multiple ChronoDB databases.
A software to store, (PUT) meteorological data from complex free form text format to databases and and GET stored (and already loaded) data from databases using OPeNDAP protocol. Written using Java6, XSD, and C++. It support OPeNDAP clients thanks to
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.
db4o is the world's leading open source object database for Java and .NET. Leverage fast native object persistence, ACID transactions, query-by-example, S.O.D.A object query API, automatic class schema evolution, small size (http://developer.db4o.com)
A Generic Object Server which transmits objects in the form of XML. This acts like a HTTP server and FTP server in one, but will store and transmit information in XML, and can be interfaced through a client, or through an API.
Ridiculously simple, Prevayler provides transparent ACID persistence and replication for plain old Java objects. It is literally several thousand times faster than using a relational database through JDBC.
Orient is 100% Pure ODBMS. It works with classes and objects instead of tables and records. Orient supports C++ language using ODMG 3.0 interface and Java using JDO 1.0.
It's available as Just Edition, a small library, or as Enterprise Edition with dis
JPO (Jigs Persistent Objects) is the persistence layer for 'Jigs for Java' web applications, extracted here for use outside of 'Jigs'. JPO supports Domain-Driven Design while embracing the use of SQL snippets for object-based queries.
Persistence Framework for J2ME; DAO layer for MIDP. It enables the developer to Query Value/Data Objects in a RecordStore. Contains methods like dao.save(vo), dao.update(vo), dao.delete(vo) and dao.findContaining(Class vo, String where).
XORM is an extensible object-relational mapping layer for Java
applications. It provides interface-based persistence to RDBMSs using the Java Data Objects (JDO) API while allowing developers to focus on the object model, not the physical layer.
The ObjectBase Project could have been called Object Oriented DataseBase but we found at least two contradictions in that. This is not object oriented, it is just objects. This is not a database because we do not persist data, we persist objects.
A unique persistence layer for Java. CODO (Cursor Oriented Data Objects) maps generated Entity interfaces (suitable for DTOs) to a relational database via rendered SQL, reflection and JDBC Cursors where possible - avoiding associations.
This project is no longer being pursued. There are several JDO impls undergoing development including OJB, XORM, TJDO, etc. Give them a try!
Sparrow is a high performance transparent persistence service (aka. Object Database) implementing the Java Dat
jUDO (java Universal Data Objects) handles coding against a database Independent of database (plugins for db2/Oracle/Cloudscape/mysql/mysql etc).The code is generated "runtime" , just give the method names and jUDO derives the code/sql.
Digital Library (DigLib) is special database system oriented to digital objects. Digital objects are any documents in digital form. For example text, software, audio, video, ... Digital Library store a metadata and fulltext (text/binary) of digital object
Tiger is an object-oriented database, written in java. It uses the concept of primary keys, aggregates, relations and indexes for finding java objects in persistent storage. Tiger have support for transactions and remote access.
Java Object DBMS stores serialized java objects in a file with keys. The keys are automatically maintained. Heavy use of introspection minimizes programming burden. Future plans include transactions, network (RMI, SOAP) access.
A lightweight versatile XQuery engine in Java, that is standards compliant and can efficiently evaluate XQueries on various containers of data -- even normal Java objects.
