JumpBox for the PostgreSQL Relational Database Management System 1.1.5 is described as a convenient as well as powerful object-relational database system that's been under active development for over 15 years.

An enterprise class database, PostgreSQL boasts sophisticated features such as Multi-Version Concurrency Control (MVCC), point in time recovery, tablespaces, asynchronous replication, nested transactions (savepoints), online/hot backups, a sophisticated query planner/optimizer, and write ahead logging for fault tolerance. It supports international character sets, multibyte character encodings, Unicode, and it is locale-aware for sorting, case-sensitivity, and formatting. PostgreSQL has a SQL implementation that strongly conforms to the ANSI-SQL 92/99 standards.

It has full support for subqueries (including subselects in the FROM clause), read-committed and serializable transaction isolation levels. This JumpBox includes PostgreSQL 8 along with PHPPgAdmin setup and ready to run. The PostgreSQL server is network accessible and provides a great storage engine for a broad array of applications.

Deploying an application as a JumpBox provides a dramatically-reduced path to getting started with the software. Aside from installation benefits it yields other advantages such as portability across computing environments and simplified ongoing maintenance of the application.

This JumpBox is free so there's no risk in trying it out. Download it today and experience for yourself a whole new way of working with server software.

1. Self-contained deployment means easy to move or delete - it won't scatter files all over your operating system.
2. New versions of the JumpBox contain updates to each component in the software stack so there's no patching web servers, application servers, databases, dependencies, etc.
3. A web-based administration console simplifies the management of your application including SSL certs, email relaying, SSH, backups and more.
4. Once you know how to install a JumpBox you can deploy any of 50+ other JumpBoxes and take advantage of a growing library of conveniently-packaged Open Source software.

MySQL Database Server 5.1.35 is a versatile and innovative tool which is designed for enterprise organizations delivering business critical database applications. It gives corporate developers, DBAs and ISVs an array of new enterprise features to make more productive developing, deploying, and managing industrial strength applications. If you need a GUI for MySQL Database, you can download - NAVICAT (MySQL GUI). It supports to import Oracle, MS SQL, MS Access, Excel, CSV, XML or other formats to MySQL.

MySQL Database Server delivers new enterprise features, including: ACID Transactions to build reliable and secure business critical applications. Stored procedures to improve developer productivity. Triggers to enforce complex business rules at the database level. Views to ensure sensitive information is not compromised. Information schema to provide easy access to metadata. Distributed transactions (XA) to support complex transactions across multiple databases.

H2 is an SQL database engine written in Java (but also available as a native binary). JDBC and ODBC APIs are supported.

- Sequence and autoincrement columns
- Well tested (high code coverage, randomized stress tests)
- Small footprint (smaller than 1 MB)
- Uses a small number of database files
- Can be compiled to native code using GCJ
- Primary keys, multiple index types (b-tree, linear hash, tree, hash)
- ORDER BY, GROUP BY, HAVING, UNION, LIMIT
- Information Schema

- The database can generate SQL script files
- Support for linked tables, and a built-in virtual range table
- Automatic re-compilation of prepared statements
- Sophisticated trace options
- Low memory requirements
- Easy to understand exception messages
- Standard handling of NULL values
- Multilanguage console application (at this time, English and German).

Enhancements
- Shell tool: the built-in commands EXIT, HELP, ?, LIST, and so on didnt work with a semicolon at the end.
- JDK 1.5 is now required to build the jar file. However it is still possible to create a jar file for Java 1.4. For details, see buildRelease.sh and buildRelease.bat. As an alternative, compile using JDK 1.5 or 1.6 and use Retrotranslator to create a Java 1.4 version http://retrotranslator.sourceforge.net/).
- When deleting or updating many rows in a table, the space in the index file was not re-used in the default mode (persistent database, b-tree index, LOG=1). This caused the index file to grow over time. Workarounds were to delete and re-created the index file, alter the table (add a remove a column), or append ;LOG=2 to the database URL. To disable the change, set the system property h2.reuseSpaceBtreeIndex to false.
- Identifiers with a digit and then a dollar sign didnt work. Example: A1$B.
- MS SQL Server compatibility: support for linked tables with NVARCHAR, NCHAR, NCLOB, and LONGNVARCHAR.
- Android: Workaround for a problem when using read-only databases in zip files (skip seems to be implemented incorrectly on the Android system).
- Calling execute() or prepareStatement() with null as the SQL statement now throws an exception.
- Benchmark: the number of executed statements was incorrect. The H2 database was loaded at the beginning of the test to collect results, now it is loaded at the very end. Thanks to Fred Toussi from HSQLDB for reporting those problems. However the changed do not affect the relative performance.
- H2 Console: command line settings are no longer stored in the properties file. They are now only used for the current process, except if they are explicitly saved.
- Cache: support for a second level soft-references cache. To enable it, append ;CACHE_TYPE=SOFT_LRU (or SOFT_TQ) to the database URL, or set the system property h2.cacheTypeDefault to "SOFT_LRU" / "SOFT_TQ". Enabling the second level cache reduces performance for small databases, but speeds up large databases. It makes sense to use it if the available memory size is unknown. Thanks a lot to Jan Kotek!

Hibernate Log4j Appender is a Log4j appender that logs to a database using hibernate.
