The unixODBC project provides Unix applications with the same ODBC 3.51 API and facilities available under Windows. It provides a Driver Manager that supports the full ODBC API and performs the ODBC 3 to ODBC 2 translations with UNICODE to ANSI conversion. It also includes a set of graphical utilities that allow users to specify connections to DBMSes to be used by applications, a collection of ODBC drivers including a simple text based driver, an NNTP driver, a Postgres driver and others, and a selection of templates and libraries that to aid in the construction of ODBC drivers. It works with MySQL, Postgres, StarOffice/OpenOffice, Applixware, iHTML, PHP, Perl DBD::ODBC, and many other applications and drivers. Connection pooling is also provided to increase performance with applications such as PHP.
Websqlbrowse is a web-based SQL database browser. Browses may be restricted and customized, and records may be added, edited, or deleted. Websqlbrowse currently works only with MySQL. While it is not currently in active development, it's still a fast, lightweight DB interface that is fairly easy to set up and is currently in use by quite a few people around the globe.
WWWdb allows you to set up an application-framework which is based on a database. It allows per-user sessions and provides the ability to insert, update, delete, and browse your database-tables. It uses plugins to ensure data-integrity and to define the layout for every application-form. It supports PostgreSQL, MySQL, InterBase, ODBC and Oracle. It is internationalized and contains translations for English and German, and has a wizard for the creation of applications over the Web and supports direct download from the database to Palm PDAs.
Xbase (formerly known as xdb) is an XBase compatible C++ class library. It provides C and C++ programmers with a cross-platform class and function library for manipulating Xbase type datafiles and indexes. There is support for .DBF and .NDX files (including support for Dbase III and IV memo fields, dates, and record and file locking), and limited support is also supplied for .NTX (clipper index) files. There is also an HTML user interface class which works well with the Apache Web Server.
XDBM is a database designed specifically to handle XML data. It offers greater speed (since the data is stored in a preparsed format), lower memory usage (since only those parts of the file needed are loaded into memory) and faster searching for XML elements. XDBM can also parse and store plain text XML files. XDBM aims to be as close to the W3's DOM specification as possible. XDBM also comes with utilities for converting between XDBM file format and plain text and for reading XDBM files in less and emacs.
XML-DBMS is a set of Java packages for transferring data between XML documents and relational databases. It views the XML document as a tree of objects in which element types are generally viewed as classes and attributes and PCDATA as properties of those classes. It then uses an object-relational mapping to map these objects to the database. An XML-based mapping language is used to define the view and map it to the database.
XML-DBMS (Perl) is a port of the Java version of XML-DBMS. XML-DBMS is middleware for transferring data between XML documents and relational databases. It views the XML document as a tree of data-specific objects in which element types are generally viewed as classes and attributes and PCDATA as properties of those classes. It then uses an object-relational mapping to map these objects to the database. An XML-based mapping language is used to define the view and map it to the database.
xml2sql is a collection of Perl script to convert XML files into SQL scripts for creating tables in a database. The generated SQL scripts are commented with the descriptions you provide in your XML, so it it easy to figure out what does what. xml2sql does no validation of your XML files.
XSet is a performance oriented main memory XML database and query engine. XSet is meant to be a low level application component that enables applications to have high speed access to stored metadata in the form of XML documents. In order to achieve the highest possible performance, XSet does not support the notion of transactions. Compared to its industry and research counterparts, XSet is miniscule. It uses a simple subset query model which is surprisingly complete for its current set of target applications. Examples of XSet applications include metadata file systems, searchable email clients, user preference registries, service discovery services, and online customized content portals. Performance evaluations have shown XSet to scale logarithmically to dataset size, and can handle hundreds of request per second on off the shelf desktop machines.
