Eclipse Data Tools (DTP)

claimed by Eclipse Foundation

The Eclipse Data Tools Platform provides extensible frameworks and exemplary tools, enabling a diverse set of plug-in offerings specific to particular data-centric technologies and supported by the DTP ecosystem.

benerator

benerator is a framework for creating realistic and valid high-volume test data, used for testing (unit/integration/load) and showcase setup. Metadata constraints are imported from systems and/or configuration files. Data can be imported from and exported to files and systems, anonymized or ... [More] generated from scratch. Domain packages provide reusable generators for creating domain-specific data as names and addresses internationalizable in language and region. It is strongly customizable with plugins and configuration options. [Less]

Jailer

Jailer is a tool for database subsetting and sampling, schema browsing, and rendering. It exports consistent, referentially intact row-sets from relational databases. It removes obsolete data without violating integrity. It is DBMS agnostic (by using JDBC), platform independent, and generates DbUnit ... [More] datasets, hierarchically structured XML, and topologically sorted SQL-DML. Features * Exports consistent and referentially intact row-sets from your productive database and imports the data into your development and test environment. * Improves database performance by removing and archiving obsolete data without violating integrity. * Generates hierarchically structured XML, topologically sorted SQL-DML and DbUnit datasets.

Xedlib

Simple to use library that handles a lot of things for you.

QueryFramework

A simple framework for building sql statements in an object oriented way, executing sql statements with database independency and providing simple object persistence.

Generic Database Accessor Library

GDALib is a layer on top of ADO.NET which hides the complexity of a lot of database operations. It simplifies many common tasks by allowing the programmer to execute SQL queries against a database, without having to worry about connections, exception handling and logging.

ursql

UrSQL: Data Storage for JavaUrSQL is a persistent storage API for Java Desktop Applications. Unlike other SQL variants, UrSQL doesn't require any kind of server or driver. It's usage is as simple as storing data should be. Loading a database file is as easy as UrSQLController ... [More] controller = new UrSQLController("database.udb");Writing Data to the DatabaseUrSQL stores entries as key value pairs. Groups of entries are called entities, each with a unique numerical ID. To create a new entity, which will store key-value entries: UrSQLEntity entity = controller.createEntity();Now, we can create a new entry: UrSQLEntry entry = new UrSQLEntry("key", "value");This entry now has the key/value pair "key: value". However, we have not specified what entity it belongs to yet. To do so: entity.addEntry(entry);Now, we can write our entry to the database: controller.writeEntry(entry);We could also write the entire entity to the database: controller.writeEntity(entity);Reading Data From the DatabaseUrSQL can search its database for particular entities and entries based on queries containing key/value pairs. For example, the following finds the entity where "key1" has a value of "value1" and "key2" has a value of "value2": UrSQLEntity entity = controller.getEntity("key1: value1; key2: value2");Notice that the colon (:) is used to separate keys and values, and the semi-colon (;) is used to separate key/value pairs. The spaces after the colon and semicolon are not necessary, but make the code a bit easier to read. Now, you can access individual entries from the entity with their key names: UrSQLEntry entry = entity.getEntry("key1");The entry object contains the entry's key and value, which can be accessed with: String key = entry.getKey(); String value = entry.getValue();Or, if you don't want to access an entire entity, you can also access a single entry using a query. This query uses known values in the same entity to search out the correct entry within the correct entity. For example, if we know that an entry with the key "key1" is contained in the same entity as an entry with the key "key2" and value "value2", then we can use the following: UrSQLEntry entry = controller.getEntry("key1", "key2: value2");Or, the second argument can be the actual UrSQLEntity that houses the desired entry. The entry can then be accessed and changed accordingly. Remember no data is actually written to the database until writeEntry or writeEntity is called by the controller object. [Less]
