XML to DDL is a set of python programs to convert an XML representation of a schema into a database and vice versa. It can also examine the differences between two databases and emit the ALTER DDL statements required to bring the database up-to-date. This
Finding the best approach when accessing a database from Java can be a daunting task. The most common solution is to program directly to the JDBC (Java Database Connectivity) APIs. The result is hard-to-read source files, bloated with complex code that ha
jLynx is a simple, lite, hi-performance layer over the JDBC API. Persist and retrieve POJO and Map objects directly. Designed for developer productivity. Simpler, easy to learn, easy to configure as compared to Hibernate, JPA, etc.
jLynx generates JavaBean objects based on your database schema. For example if you have 24 tables and views in your database, jLynx will create 24 objects with properties that map to the field names in each table. The jLynx Generator creates the objects and compiles them. You can also use the generated source instead if you prefer to customize the objects. Using the API to persist objects is trivial.
jLynx Framework implements the Relational interface, which has all necessary methods to persist objects and fetch entire collections of objects.
jLynx leverages the strengths of SQL and the strengths of Java without having to write/maintain J2EE code. It is truly the best of both worlds.
he Schemaverse is a space-based strategy game implemented entirely within a PostgreSQL database. Compete against other players using raw SQL commands to command your fleet. Or, if your PL/pgSQL-foo is strong, wield it to write AI and have your fleet command itself!
The Generic Model Organism Database (GMOD) Project is a largely open source project to develop a complete set of software for creating and administering a model organism database. Components of this project include genome visualization and editing tools,
Talend has the most open and powerful data management solutions available as a packaged, out-of-box, ready-to-install platform.
Talend's fundamental technology breaks with the market's leading proprietary solutions, associated with the open source model, significantly modifying the rules of the game in the data integration market.
SuperQuaiL is a Java SQL query builder. The goal of SuperQuaiL is to help Java developers who code SQL run and create queries easier. Other database tools focus on making it easy to do database administration and it is nice to be able to inspect the database through these tools. PhpMyAdmin, for example, a is nice web front end that you can run from multiple computers, but the interface is clumsy for the developer. For development, building queries is the main task and having a small program that loads quickly is more helpful than having a complicated interface where you can find out almost anything about the database. SuperQuaiL provides nice features to aid in the process of developing queries quick and easy.

A Scala ORM and DSL for talking with Databases with minimum verbosity and maximum type safety
Write compiler validated statements.
Squeryl statements that pass compilation won’t fail at runtime. Refactor your schema as often as is required, the Scala compiler and your IDE will tell you exactly which lines of code are affected.
Never repeat yourself
The Composability of Squeryl statements allows you to define them
once and reuse them as sub queries within other statements.
Write declaratively
Write as declaratively as SQL, only with less boilerplate. SQL’s declarativeness is preserved, not encapsulated in a lower level API that requires imperative and procedural code to get things done.
Explicitly control retrieval granularity and laziness
A significant part of optimizing a database abstraction layer is to choose for every situation the right balance between fine and large grained retrieval, and the optimal mix of laziness and eagerness. Data retrieval strategies are explicit in Squeryl rather than driven by configuration like current generation Java ORMs read more
