Oracle Berkeley DB Java Edition is a high performance, transactional storage engine written entirely in Java. Like the highly successful Berkeley DB product, Berkeley DB Java Edition executes in the address space of the application, without the overhead of client/server communication.
It stores data in the applications native format, so no runtime data translation is required. Berkeley DB Java Edition supports full ACID transactions and recovery. It provides an easy-to-use, programmatic interface, allowing developers to store and retrieve information quickly, simply and reliably.

Main features:
- Local, in-process data storage.
- Schema-neutral, application native data storage.
- Keyed and sequential data retrieval.
- Easy-to-use Java Collections API.
- Persistence API for accessing Java objects.
- Single process, multi-threading model.
- Record level locking for high concurrency.
- Support for secondary indexes.
- In-memory, on disk or both.
- Configurable background cleaner threads re-organize data and optimize disk use.
- Full ACID compliance.
- Selectable isolation levels and durability guarantees, configurable on a per-transaction basis.
- Managed transactions using the Java Transaction API (JTA).
- J2EE application server integration using J2EE Connector Architecture(JCA).
- Provides support for monitoring, auditing and administration using the Java Management Extensions (JMX).
- Catastrophic and routine failure recovery modes.
- Timeout based deadlock detection.
- Hot and cold backups, log file compaction, and full database dumps.
- 100% pure Java for portability and ease of development.
- Single JAR file - easy to install, runs in the same JVM as the application.
- Java 1.4.2 or later Standard Edition JVM required.
- Programmatic administration and management-zero human administration.
- API for routine administrative functions.
- Small footprint 772KB.
- Scalable to terabytes of data, millions of records.
- Source code, test suite included.

Enhancements
- Fix a bug that somtimes causes two log cleaner threads (when multiple threads are configured or multiple app threads call Environment.cleanLog) to select the same file to clean. This can result in two attempts to delete the log file after cleaning. The second attempt causes an exception to be traced repeatedly, but no other side effect. The problem is transient and goes away if the Environment is closed and re-opened. An example of the exception is below. The symptom is that this exception occurs repeatedly, and the file is not present.
- Fix a bug that could cause a LogFileNotFoundException when using an XAEnvironment, if a prepared transaction is not ended prior to a crash and then the prepared transaction is aborted after recovering from a crash. [#17022] (3.3.79)
- Fix a bug that prevented deferred-write record deletions from being made durable by Database.sync, if a crash occurs after Database.sync but prior to the next checkpoint. Under rare circumstances this could also result in a LogFileNotFoundException later when accessing the deleted entry. [#16864] (3.3.78)
- Fix a bug that prevents log cleaning from functioning properly when a temporary DB (DatabaseConfig.setTemporary) is large enough to overflow the JE cache. Also fix a bug that could in rare cirumstances cause an endless loop while performing log cleaning. [#16928] (3.3.78)
- Fix a bug that caused an infinite loop under certain timing dependent circumstances when using EnvironmentConfig.setSharedCache(true). This bug was reported in two different forum posts. Thanks to Kevin Jackson and Vyacheslav Lukianov for reporting it! [#16882] (3.3.78)
- Improve output of partial information in DatabaseEntry.toString. Thanks to archie172 for reporting this on OTN. [#16929] (3.3.78)
- Fix a bug in SecondaryCursor.dup that required the cursor to be initialized. This method, like Cursor.dup, may now be called whether the cursor is initialized or not. Thanks to archie172 for reporting this on OTN. [#16930] (3.3.78)
- Fix a bug that caused NullPointerException when opening an XAEnvironment under certain circumstances, when prepared but uncommitted transactions are present in the JE log and must be replayed during recovery. This bug was reported on the OTN forum by Matthieu Bentot -- thank you Matthieu! An example of the stack trace is below.
- Fix a bug that caused LogFileNotFoundException in rare circumstances for an Environment having one or more Databases configured for duplicates (or one or more SecondaryIndexes with MANY_TO_XXX relationships). The bug only occurs when a single secondary/duplicate key value is associated with a large number of records/entities; specifically, the sub-Btree for a single duplicate key value must have at least 3 levels. [#16712] (3.3.76)
- Fix a bug that caused BufferOverflowException while writing transactional records. This could occur if multiple threads were writing to an environment while using the same Transaction. [#17204]
- Direct Persistence Layer (DPL), Collections and Bind packages - Fix a bug that causes the EvolveStats returned by EntityStore.evolve to contain zeros, even when entities are evolved and written, when no EvolveListener is configured. Thanks to jhalex on OTN for reporting this. [#17024] (3.3.78)

PostgreSQL Database Server 8.3.0 is a program functioning as an open source relational database system. It has more than 15 years of active development and a proven architecture that has earned it a strong reputation for reliability, data integrity, and correctness. It runs on all major operating systems, including Linux, UNIX (AIX, BSD, HP-UX, SGI IRIX, Mac OS X, Solaris, SunOS, Tru64), BeOS, and Windows. PostgreSQL Database server already embedded a useful GUI - PGadmin. If you want to import MS Access or other formats to PostgreSQL, you can install a Mac OS X GUI Navicat PostgreSQL

PostgreSQL is an open-source descendant of this original Berkeley code. Also, PostgreSQL can be extended by the user in many ways.

It supports a large part of the SQL:2003 standard and offers many modern features:

1. Complex queries
2. Foreign keys
3. Triggers
4. Views
5. Transactional integrity
6. Multiversion concurrency control

Tokyo Cabinet is the successor of QDBM, a high performance database library similar to the DBM family.
Tokyo Cabinet also supports hash and B-tree databases and doesnt require any server process. The overall speed is improved compared to QDBM.

Main features:
- smaller size of database file.
- faster processing speed.
- higher performance in multi-thread environment.
- improves usability : simplified API.
- improves robustness : database file is not corrupted even under catastrophic situation.
- supports 64-bit architecture : enormous memory space and database file are available.

Netatalk is a freely-available, kernel level implementation of the AppleTalk Protocol Suite, originally for BSD-derived systems. A *NIX/*BSD system running netatalk is capable of serving many macintosh clients simultaneously as an AppleTalk router,
AppleShare file server, *NIX/*BSD print server, and for accessing AppleTalk printers via Printer Access Protocol (PAP). Included are a number of minor printing and debugging utilities.
NOTE: Netatalk is licensed and distributed under the terms of the BSD License and GNU General Public License (GPL).

System requirements:

- perm value OR with the client requested permissions. (help with OSX 10.5
- strange permissions).
- Make dot files visible by default with usedots, use invisibledots
- for keeping the old behavior, ie for OS9 (OSX hide dot files on its
- own).

- FIX: cnid: dbd detach the daemon from the control terminal.
- UPD: cnid: never ending Berkeley API changes...
- UPD: cnid: dbd add a timeout when reading data from afpd client.
- UPD: cnid: Dont wait five second after the first error when speaking to the dbd
- backend.
