Comprehensive information about the database as a whole.
This interface is implemented by driver vendors to let users know the capabilities of a Database Management System (DBMS)
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.
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.
QuantumDB is a simple but powerful database access plug-in for the Eclipse Development Platform. QuantumDB allows you to:
* connect to databases using standard JDBC drivers
* review schemas, tables, views and sequences
* look up column, index and foreign key information
* issue ad-hoc queries or other SQL statements against the database
* manage, edit, and work with SQL files (*.sql)
* issue updates, deletes, and inserts using simple, easy-to-use wizards
dbdeploy is a Database Change Management tool. It helps developers and
DBAs change their database in a simple, controlled, flexible and
frequent manner
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.
The goal is to create an eclipse plugin to design and edit entity relationship diagrams. On the other side, the plugin should also be able to create SQL and Java-Code (Hibernate) out of the diagrams.
"Java DB is Sun's supported distribution of the open source Apache Derby 100% Java technology database. It is fully transactional, secure, easy-to-use, standards-based -- SQL, JDBC API, and Java EE -- yet small, only 2MB."
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
The iBATIS Data Mapper framework makes it easier to use a database with Java and .NET applications. iBATIS couples objects with stored procedures or SQL statements using a XML descriptor. Simplicity is the biggest advantage of the iBATIS Data Mapper over
