The invention concerns a method for organizing a digital database in a traceable form, comprising steps which consist in modifying a main digital database by adding or suppressing or changing a record of the main base and steps which consist in reproducing the main database. The invention is characterized in that the step of modifying the main database includes an operation which consists in creating at least one digital recording comprising at least: the unique digital identifiers of the relevant records and attributes of the main database, a unique digital identifier of the state of the main database corresponding to said modification of the main database, the elementary values of the attributes assigned to them through the elementary operations, without storing the unmodified attributes and records, and adding said record in an internal historization base consisting of at least one table, and in that the reproduction step concerning any final or prior state of the main database consists in receiving (or intercepting) an original request associated with the identifier of the state concerned, in transforming said original request to constitute a modified addressing request of the historization base comprising the criteria of the original request and the identifier of the state concerned, and reconstituting the record(s) corresponding to the criteria of the original request and to the state concerned, the method further comprising mechanisms enabling the monitoring of the operations, the causal dependencies and the impact of the modifications, as well as the fusion of branches or the evolution of the data structure. |
