4store
4store is a database storage and query engine that holds RDF data. 4store's main strengths are its performance, scalability and stability. It does not provide many features over and above RDF storage and SPARQL queries, but if your are looking for a scalable, secure, fast and efficient RDF store, then 4store should be on your shortlist.
ADL
Database load balancing class for PHP applications who need to deal with various MySQL servers. The class will properly detect write queries and will try the next available server(s) until running out of connections. Multi server connection handling in progress in order to allow running transactions in many servers at the same time.
ADOdb
ADOdb is a database abstraction library for PHP. The PHP version currently supports an amazing number of databases, thanks to the wonderful ADOdb community: MySQL, PostgreSQL, Interbase, Firebird, Informix, Oracle, MS SQL, Foxpro, Access, ADO, Sybase, FrontBase, DB2, SAP DB, SQLite, Netezza, LDAP, and generic ODBC, ODBTP. The Sybase, Informix, FrontBase and PostgreSQL, Netezza, LDAP, ODBTP drivers are community contributions. Some reasons why ADOdb is popular include:
  • Designed for speed. It is probably the fastest free software database abstraction library available for PHP. See benchmarks.
  • Provides extensive portability support such as date and type-handling and portable schema creation. See portable sql tips
  • Support many enterprise features such as database backed sessions (with session expiry notification), SQL code generation, pivot tables, SELECT LIMIT emulation for all databases, performance monitoring.
  • Easy to learn.
  • Extensive QA, every release is unit-tested on Access, MySQL, PostgreSQL, MS SQL, Oracle 9.
  • Mature, continuously developed since August 2000. Has a large community of users.
  • Powerful Active Record support. See docs.
  • Very reasonable licensing terms (BSD). This means that you can incorporate (and even compile) it into your software applications royalty-free without asking the author's permission, provided you include license.txt in your release.
ADOdb Lite
A small, fast replacement for ADODB that uses 1/6th of the memory and upto 300% faster while being compatible with ADODB using a subset of the most often used ADODB commands.. Supports Frontbase, MaxDB, MiniSql, MSSQL, MySql, Postgres, SqLite and Sybase.
ADOdb for Python
ADOdb is a database abstraction library. ADOdb was originally developed for PHP, and ported to Python. The Python version implements a subset of the PHP version. You might ask why Python needs a database abstraction library when Python provides the official DB API. Unfortunately the DB API does not encapsulate differences in the database implementations. For example, to select a limited number of rows, say 10 rows, you would have to use very different SQL for different databases:
  • MS SQL select top 10 from table
  • MySQL and PostgreSQL select * from table limit 10
  • Oracle select * from (select * from table) where rownum <= 10
  • These differences are handled by ADOdb (using SelectLimit), but not by the Python DB API. Other important database differences transparently handled by ADOdb include date-formating, associative arrays (records as dictionaries) and LOB-handling.
AE-DIR
Authorized Entities Directory (Æ-DIR) is a Privileged Identity and Access Management (IAM/PIM/PAM) based on OpenLDAP Objectives:
  • Strictly follow need to know and least privilege principles
  • Agile data maintenance by consequent delegation of manageable small areas
  • Provide meaningful audit trails for compliance checks
  • Secure defaults
AOLserver
AOLserver is a multithreaded, TCL-enabled, massively scalable and extensible Web server designed for large scale, dynamic Web sites such as Digital City and AOL.COM. It includes complete database integration, dynamic page scripting, and an open, extensible architecture.
APAz
aPAz is An ultra-light PHP AnonymiZer. It is intended to be a "Put it anywhere, browse everywhere application". You can use it on any Web server that uses PHP and allows socket functions.
AWStats
Advanced Web Statistics is a free tool that generates advanced web server access statistics graphically. This web server log analyzer works as a CGI or from command line and shows you all information your log contains, in few graphical web pages. It can analyze IIS 5.0+, Apache log files and some other web servers (log files with a personalized format are supported since version 3.0). It's the best statistics tool for web server with less than 200,000 visits a month. The program can measure visits, unique vistors, pages, domains/countries, OS busiest times, robot visits, search engine/keyword used, and HTTP errors. Statistics can be updated from a browser or your scheduler. The program also supports virtual servers.
Academic Teaching Planner
Academic Teaching Planner is a free software useful to plan university courses and various types of tests. It is designed as a personal tool beside management software used by academic institutions, and allows to: 1. manage and archive the documentation of each single course (objectives, bibliography, dates, information texts, lessons, files of all kinds, etc.) as well as the results of the tests, even the intermediate ones that are not always stored in management systems used by academic institutions; 2. manage the list of students who are enrolled in each individual course, easily retrieving their data from the management system in use at the academic institution, and their tests; 3. compare the distribution of bibliographic resources in the various lessons, made by the professor, with a reference model obtained by their homogeneous distribution throughout the course, to verify, also with the aid of diagrams, that the supposed planning is substantially realistic, that is, can be completed on schedule without omitting topics or lessons in excess. Academic Teaching Planner is a cross-platform software that runs natively on GNU/Linux, Windows and macOS. It manages data with Sqlite, a well-known and reliable database, while saving attachments (i.e. files of any kind associated with the various sections of the software) in an external folder, in a transparent way for the user. Their number and size are limited only by the space available on the computer in use. Academic Teaching Planner has been written with Lazarus (www.lazarus-ide.org) and uses the Sqlite database through the Zeos components (sourceforge.net/projects/zeoslib).
