FireStorm/SDO

 Home Page Home Page
Categories:
Author: CodeFutures
Latest version: 1.0 Early Access 2
Description: Generates Java code for accessing databases using the Service Data Object (SDO) API.

FireStorm/SDO consists of:
- an SDO Runtime: can be used as part of a standalone application running in J2SE or as part of an enterprise application running in J2EE. FireStorm/SDO provides a Data Access Service for reading data from relational databases and populating a DataGraph consisting of DataObjects and a Change Summary. This DataGraph can then be modified offline from the database and then sent back to the Data Access Service, which contains the functionality to apply the changes to the relational database.
- an SDO Code Generation Tool: can import existing database schemas (from a SQL script or from a live JDBC connection) and can then generate a static Java SDO API for accessing the database. The generated code extends the SDO Dynamic API giving the developer the choice of using static or dynamic DataObjects as defined by the SDO specification.

NeuralBuild

 Home Page Home Page
Categories:
Author: NeuralLimits
Latest version: 1.2
Description: Code generator that automatically generates Java, PHP and C# source code for accessing relational databases.
NeuralBuild generates code for Java and PHP with the Data Access Object (DAO) design pattern (DAO is a core J2EE design pattern), for C# NeuralBuild generates code for the DALC (Data Access Layer Components) pattern.

For C#, NeuralBuild generates a DALC tier based on .NET database connectors and SQL calls. The DALC components hide the invocation and format idiosyncrasies of the database from the calling application. DALC components provide an encapsulated data-access service to these applications.

XStream

 Home Page Home Page
Categories:
Latest version: 1.2.1
Description: Library to serialize objects to XML and back again.

Features include:
- A high level facade is supplied that simplifies common use cases.
- Most objects can be serialized without need for specifying mappings.
- Designed for speed and low memory footprint, making it suitable for large object graphs or systems with high message throughput.
- No information is duplicated that can be obtained via reflection. This results in XML that is easier to read for humans and more compact than native Java serialization.
- Requires no modifications to objects: Serializes internal fields, including private and final. Supports non-public and inner classes. Classes are not required to have default constructor.
- Full object graph support: Duplicate references encountered in the object-model will be maintained. Supports circular references.
- Integrates with other XML APIs. By implementing an interface, XStream can serialize directly to/from any tree structure (not just XML).
- Customizable conversion stategies: Strategies can be registered allowing customization of how particular types are represented as XML.
- Error messages: When an exception occurs due to malformed XML, detailed diagnostics are provided to help isolate and fix the problem.

JaxMe 2

 Home Page Home Page
Categories:
Author: The Apache Software Foundation
Latest version: 0.5.2
Description: Open source implementation of JAXB, the specification for Java/XML binding.

A Java/XML binding compiler takes as input a schema description (in most cases an XML schema but it may be a DTD, a RelaxNG schema, a Java class inspected via reflection or a database schema). The output is a set of Java classes:
- A Java bean class compatible with the schema description. (If the schema was obtained via Java reflection, then the original Java bean class.)
- An unmarshaller that converts a conforming XML document into the equivalent Java bean.
- Vice versa, a marshaller that converts the Java bean back into the original XML document.
In the case of JaxMe, the generated classes may also:
- Store the Java bean into a database. Preferrably an XML database like eXist, Xindice, or Tamino, but it may also be a relational database like MySQL.
- Query the database for bean instances.
- Implement an EJB entity or session bean with the same abilities.

Torque

 Home Page Home Page
Categories:
Author: The Apache Software Foundation
Latest version: 3.2
Description: Torque does not use reflection to access user-provided classes, but it generates the necessary classes from an XML schema describing the database layout (which can either be written by hand or generated from an existing database). The XML schema can also be used to generate and execute a SQL script which creates all the tables in the database.
As Torque hides database-specific implementation details, it makes an application independent of a specific database if no exotic features of the database are used.
You can override the autogenerated methods and thus change their behaviour.

Torque consists of:
- runtime: contains everything to allow an application to access the database. It is the only component of Torque needed in your application and can be used standalone.
- Maven plugin: creates the object classes for accessing and storing data from the database. It can also generate the XML description of an existing database and (in reverse) create an SQL script to create the tables in the database. Internally, the Maven plugin uses the generator to accomplish these tasks.
- generator: contains Ant tasks that do all the work for the Maven plugin.
- templates: contain the building blocks used by the generator to create the object classes, SQL scripts and the like. You can change the templates if you want to customize the output of the generator.
