The Apache Open For Business Project is an enterprise automation software project that includes ERP, CRM, E-Business/E-Commerce, SCM, MRP, and CMMS/EAM functions. It is a foundation and starting point for enterprise solutions and can certainly be used out of the box, but is also great for creating specialized applications.
nexB OpenAssets is a tool for inventorying, managing, and monitoring applications, software, hardware, networks, and generally any IT asset. It is designed so that system administrators, IT, and finance can determine what they have, how it is configured, what it is used for, and how much it is being used, so that informed decisions can be made. It complements existing network management software, integrates with a growing number of protocols and tools, and features no-agent discovery and inventory, configuration management including dependencies and correlation, monitoring, and reporting. It makes extensive and innovative use of XML, Xpath, and Xquery.
FreeSMS (Free Student Management System) is a Web application for managing an educational facility. It manages teachers and students and provides marketing, registration, course management, attendance, and a student evaluation system, and manages courses within a class environment. Profile-based management is supported for administrators, teachers, and students. Teachers and students can be registered online. Students are allowed to manage their own class enrolment and submit course evaluations, and teachers can manage student attendance. The differential factor and elegance of this project lie in the OOP standard and a modular structure. The code is clean and very extendable.
