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 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 ·
SQLRunner is a simple JDBC Client which helps Java developers with various methods. You can build, test and run select, update and DML statements (also callable statements with out put parameters) and export or import data in/from csv-files or XML-fi ·
Sqoop is a tool designed to import data from relational databases into Hadoop. Sqoop uses JDBC to connect to a database. It examines each table’s schema and automatically generates the necessary classes to import data into the Hadoop Distributed File System (HDFS). Sqoop then creates and launches a MapReduce job to read tables from the database via DBInputFormat, the JDBC-based InputFormat. Tables are read into a set of files in HDFS. Sqoop supports both SequenceFile and text-based target and includes performance enhancements for loading data from MySQL. ·
AutoPatch was born from the needs of using an agile development process while working on systems that have persistent storage. Without AutoPatch, developers usually can't afford the maintenance headache of their own database, and DBAs are required just to apply changes to all of the various environments a serious development effort requires.
The very application of database changes becomes an inefficient, error-prone, expensive process, all conspiring to discourage any refactoring that touches the model, or being a bottleneck when model changes are made.
AutoPatch solves this problem, completely.
With AutoPatch, an agile development process that requires a database change looks like this:
* Developer alters the model, which requires a change to the database
* Developer possibly consults a DBA, and develops a SQL patch against their personal database that implements the alteration
* Developer commits the patch to source control at the same time as they commit their dependent code
* Other developers' and environments' databases are automatically updated by AutoPatch the next time the new source is run
This represents streamlined environment maintenance, allowing developers to cheaply have their own databases and all databases to stay in synch with massively lower costs and no environment skew.
That's what AutoPatch does.
Clusters with one database? Multiple schemas? Logical migrations, instead of just DDL changes? Need to do something special/custom? Need to distribute your changes commercially? All without paying anything? No problem. ·

Sphinx is a full-text search engine, distributed under GPL version 2. Commercial license is also available for embedded use.
Generally, it's a standalone search engine, meant to provide fast, size-efficient and relevant fulltext search functions to other applications. Sphinx was specially designed to integrate well with SQL databases and scripting languages. Currently built-in data sources support fetching data either via direct connection to MySQL or PostgreSQL, or using XML pipe mechanism (a pipe to indexer in special XML-based format which Sphinx recognizes).
As for the name, Sphinx is an acronym which is officially decoded as SQL Phrase Index. Yes, I know about CMU's Sphinx project. ·
The Mogwai ERDesigner is a entity relation modeling tool such as ERWin and co. The only difference is that it is Open Source and does not cost anything. It was designed to make database modeling as easy as it can be and to support the developer in the whole development process, from database design to schema and code generation. This tool was also designed to support a flexible plug in architecture, to extend the system simply by installing a new plug in. This way, everybody can implement new features and tools to make ERDesigner fit the requirements.

The Power*Architect is a user-friendly data modeling tool created by data warehouse designers, and has many unique features geared specifically for the data warehouse architect. It allows users to reverse-engineer existing databases, perform data profiling on source databases, and auto-generate ETL metadata.
Plus, the Power*Architect has the ability to take snapshots of database structures, allowing users to design DW data models while working offline.
Whether you are building a Data Warehouse or using data models to communicate business rules, the Power*Architect will facilitate and automate your data modeling efforts. ·
The XAware project provides real time data integration with a service-oriented flavor. XAware makes other tools and frameworks much more productive by hiding data complexity behind "XML views". XML views span any number of data sources, and can read data, write data, or transfer data between sets of sources, all within a distributed transaction. ·
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. ·
log4jdbc is a JDBC driver that can log SQL and/or JDBC calls (and optionally SQL timing information) for other jdbc drivers using the Simple Logging Facade For Java (SLF4J) logging system. ·
SQL Workbench/J is a free, DBMS-independent, cross-platform SQL query tool. It is written in Java and thus it should run on any operating system that provides a Java Runtime Environment.
It's main focus is on running SQL scripts (either interactively or as a batch), graphical query building or administration of the database is not the focus. ·
Do you hate starting on a new project and having to try to figure out someone else's idea of a database? Or are you in QA and the developers expect you to understand all the relationships in their schema? If so then this tool's for you.
SchemaSpy is a Java-based tool (requires Java 1.4 or higher) that analyzes the metadata of a schema in a database and generates a visual representation of it in a browser-displayable format. It lets you click through the hierarchy of database tables via child and parent table relationships. The browsing through relationships can occur though HTML links and/or though the graphical representation of the relationships. It's also designed to help resolve the obtuse errors that a database sometimes gives related to failures due to constraints. ·
