i want a Retail Management System (RMS) similar to Microsoft Retail Management system? with? the same? requirements(all functional and non-functional).
the software should be implemented in .NET Framework 2.0 or higher and in C# (if possible to implemented it using the MONO framework this will be and advantage)? and the database should be built with SQL server 2005 (or MySQL and PostrageSQL server).
the implementation should use a multi-tier architecture which is fully documented and all functionallity should be in COM objects(Class library)? so any further extending for the application or linking it to other systems is possible.
Documentation should also be supported (and an advantage? if there is a mapping document that maps the system functions to what is supported by Microsoft RMS).
please specify the cost of implementing such a system and the time required, faster implementation with good quality is preferable.
