Overview
Kartris is an open-source, ASP.NET ecommerce system written in VB.NET (Web Forms) and with an MS SQL database back end. It is optimized to handle sites with 1,000,000+ SKUs out-of-the-box.
Architecture
Kartris is built on a multi-tier model, with database, stored procedures, DAL, BLL and front end. Visual customization is via 'skins', a combination of master pages and CSS. The database is structured with no limit on the number of languages or currencies
that can be used. The database has been optimized so that the software is capable of running stores with well over a million SKUs out-of-the-box. The back end has been refined to handle hundreds of orders per day, and to make managing huge catalogues feasible.
Licensing
Kartris was previously only available on a proprietary license. From v2 onwards, it is available under both the GPL v2 and the Kartris Commercial License (proprietary).
