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. At the same time the integrity of the information stored in the data storage ( 170 ) is guaranteed.
