Overview of Document Imaging
Return to Image-Master Introduction
Document imaging is a way to replace physical paper documents stored in traditional file cabinets with an electronic image database. Each piece of paper is converted into digital form by a scanner. Logical groups of related pages are combined together to form a scan set and are assigned an index record to allow future lookup and retrieval of the pages. Folders contained within the file cabinets are represented by records in the database. The criteria used to identify the pages within a scan set are specified by one or more index fields.
Index fields hold values which can be words, numbers, or symbols. These values are assigned when the scan set is created. The values in the index fields are used to retrieve the scan set.
