Free what are databases software for mac

GestLab Database 22 gives you a free tool which starts with version 1.1, the application and database are separate files. In order to use it, you must download both files (GestLab and GestLab Database), and place them in the same folder.

License Database 1.0 is an innovative and versatile utility which stores software license information like serial numbers.

You all have lots of serial numbers lying around, and when ever the software needs to be reinstalled the job of finding the email with the serial number in it comes along. License Database hopes to solve this problem by providing a central storage area for all your serial numbers. Unlike other serial databases available License Database has kept things simple. The interface is clean and tidy and best of all License Database is free.

H2 is an SQL database engine written in Java (but also available as a native binary). JDBC and ODBC APIs are supported.
Embedded and server modes are available. A Web console application is included. Clustering is supported.

- Triggers and Java functions / stored procedures
- Referential integrity / foreign key constraints with cascade, check constraints
- Multiple schema support
- Compatibility modes for HSQLDB, MySQL and PostgreSQL
- 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
- Multiple connections
- Collation support
- EXPLAIN PLAN support
- 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!

Netinfo Database Loader 1.1 is created to be a tiny yet effective Filemaker pro database which assists you to import information in your local or shared Netinfo databases. It works by reformating and dumping all the entries in "raw format" that is copied in the Clipboard. Create a plain Textedit file, paste the dump in it, save it as UTF-8, then go back to the database to finish importation with AppleScript and the Terminal.

It is particularly well suited to create entries to use with OpenLDAP and Open directory in Mac OS X Server 10.2 so that you can create a shared LDAP directory to be exploited from Address Book, Entourage, or any other LDAP client.
