Epesi is an open source, PHP/Ajax framework for rapid development of web based, database driven applications. The framework includes the Epesi CRM (customer relationship management) multiuser application. It requires PHP 5.x and MySQL or PostgreSQL database server on the server side and can be accessed using any modern browser. Epesi framework and Epesi CRM application is released under MIT license. == History == Between 1995 and 2006, Teknaspan Corporation, a small IT consulting company run by Janusz Tylek, was providing computer-related services in the Greater Philadelphia metropolitan area. Many of its customers - mostly small, local companies - were looking to share easily information especially in remote offices. Setup based on Microsoft's Exchange Server, Outlook and Sharepoint was too expensive and difficult to set up and manage and did not meet with a good response. In the same time period, Internet connection became a norm and mature, free and open source software like Apache, MySQL and PHP became available. Teknaspan started offering open source solutions to its customers, among them SugarCRM. This application was difficult to set up, upgrade and most of all - difficult to extend its functionality. After experimenting with a number of other solutions like dotproject, mantis, and many other open source solutions, it became clear that there is a need for a modern framework with a set of reusable components upon which an application can be developed. At the beginning of 2006, Teknaspan Corporation was acquired by another IT consulting company. Janusz Tylek left Teknaspan and formed Telaxus LLC, a small software startup company focusing on development of web-based applications. The framework using latest standards like AJAX, HTML5 and CSS3 was born. The original requirements were: * 100% web based (no client installation needed) * run on any web server (Apache, IIS, Windows, Linux - LAMP/WAMP stack) * use the most popular web scripting language supported - PHP * provide a database abstraction layer - AdoDB, which has drivers for MySQL, PostgreSQL and many others * include authentication and permission library - phpGACL * have a set of reusable components (modules) * use of other open source application (for example Roundcube as e-mail client) In the summer of 2006, the work on the framework started after a meeting of Tylek (jasiek) and Pawel Bukowski (shacky), who designed the first set of modules. By the end of 2006, the first commercial application was released - a warehouse management system. In May 2007, the core of epesi framework was released as open source software and published on SourceForge. It included Record Browser - CRUD engine, designed by Arkadiusz Bisaga (ethnar), which is a high-level database abstraction layer, handling not only Create/Read/Update/Delete operations, but also automatic pagination, lazy delete, full record history, sorting, filtering and more. During the next twelve months, the application was expanded with customer relationship management (CRM) functionality and this package is now available as EPESI, an alternative to products like SugarCRM or vtiger. From November, 2012 epesi can be installed with Softaculous Autoinstaller 〔(epesi Softaculous Autoinstaller )〕 In August 2013 EPESI was added to Enterprise-Ready Open Source Projects on SourceForge 〔(Sourceforge Enterprise Directory - CRM )〕 and ranks as one of the top CRM and ERP applications with 5 star rating. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Epesi」の詳細全文を読む スポンサード リンク
