Scalable web-based workflow platform
The document describes a web-based workflow platform that utilizes a LAMP stack for its application architecture, offering features such as customization, integration with third-party applications, and multi-tenancy support for client data management. It includes tools for form and report creation, a sessions manager for user access, and security measures at multiple levels to protect data and application objects. The platform is designed for scalability and provides an efficient way to manage complex workflows.
