Abstract: The present invention relates to a document database for organizing text-searchable information. A data storage (170) includes an original layer database (175) and a supplementary layer database (176). The original layer database (175) stores non-editable electronic documents in a folder structure. The supplementary layer database (176), for each electronic document in the original layer database (175), stores an amendable data record including a number of logic fields. Moreover, a direct link exits between each pair of non-editable electronic document and amendable data record, such that a one-to-one relationship is established. Both the original layer database (175) and the supplementary layer database (176) are adapted to be accessed and searched via a user interface (180) and an interconnecting network (190). Thus, a highly flexible user-access to the electronic information stored in the data storage (170) is enabled.
