Java Object Base is an API providing persistence in Java.
This API introduces the concept of persistent maps extending JDK maps.
Persistent maps are processed in transactional contexts.
They support application identity as well as datastore identity.
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.
Java Object Query System(JOQS)- JOQS is a simple object/relational persistence and query service. JOQS lets you develop persistent classes using simple query string (Object Query String, QS). Just like native SQL, object query string is very...
Object Mapping Project (OMaP) proposes a way to define and to perform mappings of Java object instances. The objects could be mapped to a XML String, another Java object, database records, Swing screens, etc. And, of course, mapping back is also...
vRules4j--The best completely Object Oriented Java Object Validation/Decision Rule engine,which is born for taking over all validation responsibility in java business-enterprise industry and looking forward to providing Perfect/Lightweight solution.
Java Object Map Web Components is a set of components for building web applications based on existing object-relational models (Cayenne, etc.)
This library is an Object/Relation mapping framework for Java. It is designed to be easy to use (no xmls to write, no tables to create, no primary keys to fiddle with, just point it to the database) with automatic generator of objects.
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.
Java Object to Relational (O/R) mapping system that works with any J2EE compliant application server. Draw your class/ER diagram in Rational Rose and let JOB generate the database and Java code from your Ant build script.
This utility is used to creates Java object models from XML structure definitions(DTD&Schema) and automacitally generates intelligent codes to process the given XML file. Developers need not write painful code to process XML anymore. |
