SharePoint is a Portal solution which will provide a unified view to a customer. It will need OmniScan to scan the documents in batches as per the requirement of the customer and will put them in a desired table format from where the documents can be picked by SharePoint. At the same time SharePoint can store and retrieve the documents in a Document Management system like OmniDocs.
Apart from having a DMS in the backend one can have many other applications also running in the backend to provide necessary information to the visitor at SharePoint Portal. A Portal and a Document Management system are two different solutions having different functionalities, even though it might seems to be overlapping in some of the cases. One can even have a ERP solution running in the backend from where the Portal can fetch the information and provide to the user of Portal. This does not mean that one can replace a ERP solution by buying a Portal solution like SharePoint, even though some of the functionalities can be common here.
To help you understand more on this let me explain the concept of Portal and Document Management system separately. Kindly note all the features mentioned in a Portal solution or in a DMS solution as mentioned in this document may not be always available through one software product, for eg. For emails Microsoft uses a different software product and does not provide it under SharePoint.
What is a Portal Solution ?
A web portal or links page is a web site that functions as a point of access to information in the World Wide Web. A portal presents information from diverse sources in a unified way. Apart from the standard search engine feature, web portals offer other services such as e-mail, news, stock prices, information, databases and entertainment. Portals provide a way for enterprises to provide a consistent look and feel with access control and procedures for multiple applications and databases, which otherwise would have been different entities altogether. A Portal typically provides personalized capabilities to its visitors, providing a pathway to other content. It is designed to use distributed applications, different numbers and types of middleware and hardware to provide services from a number of different sources. In addition, business portals are designed for sharing and collaboration in workplaces. A further business-driven requirement of portals is that the content be able to work on multiple platforms such as personal computers, personal digital assistants (PDAs), and cell phones/mobile phones.
SharePoint is a portal solution which can have a Document Management System in the backend. A user can use the SharePoint user interface to access these documents instead of using the OmniDocs user interface if they wish.
What is a Document Management System ?
A document management system (DMS) is a computer program used to track and store electronic documents and/or images of paper documents. It is usually also capable of keeping track of the different versions created by different users (history tracking). The term has some overlap with the concepts of content management systems. It is often viewed as a component of enterprise content management (ECM) systems and related to digital asset management, document imaging, workflow systems and records management systems. Document management systems commonly provide storage, versioning, metadata, security, as well as indexing and retrieval capabilities.
