  • Adminer 1 Adminer
    Adminer 1 Adminer Adminer Adminer main screen Developer(s) Jakub Vrána Initial release July 25, 2007 Written in PHP Operating system Cross-platform Available in Multilingual (24) Type Web Database Management License Apache license or GPL v2 [1] Website www.adminer.org Adminer (formerly known as phpMinAdmin) is a tool for managing content in MySQL databases (since version 2 also in PostgreSQL, MS SQL, SQLite and Oracle SQL databases). Adminer is distributed under Apache license (or GPL v2) in a form of a single PHP file (around 300 KiB in size). Its author is Jakub Vrána who started to develop this tool as a light-weight alternative to phpMyAdmin, in July 2007. Adminer got some attention in 2008 when it made it to the CCA finals at SourceForge.[2] Also, first webhosting providers started to include Adminer as MySQL managing tool into their portfolio of services. In 2012 Adminer got coverage on Linux.com for the second time.[3] The project's priorities, according to its author, are (in this order): safety, user-friendliness, performance, functionality, and size.[4] Features • Users log in specifying the destination server and providing the user name and password (which is stored during whole session) • Basic functions: select database, select/edit tables, browse/insert/edit table rows • Searching or sorting via multiple columns • Editing of other database objects: views, triggers, events, stored procedures, processes, mysql variables, user permissions • Text area for arbitrary SQL commands and storing these commands in command history •
