All resources (organization, interested parties, procedures, computer systems) necessary for the collection, storage, processing and use of information. The National Service for Water Data and Reference-dataset Management (Sandre) contributes to the development of the Water Information System (WIS).
Diagram showing the structure of the information system from the data viewpoint, i.e. the dependencies or relationships between the different data of the information system: a conceptual data model (CDM) formally describes the data that will be used by the information system. The basic concepts are:
Activity for data specification or standardization even. It relies on data dictionaries. The National Service for Water Data and Reference-dataset Management (Sandre) carries out standardization work to develop specification documents.
Specifications and structured set of pieces of information used for the implementation of an information system, providing a common framework for several applications. The National Service for Water Data and Reference-dataset Management (Sandre) produces specification documents and datasets constituting the reference frame for the data of the Water Information System (WIS).
Specific attribute that uniquely identifies an object in a dataset. The National Service for Water Data and Reference-dataset Management (Sandre) produces identifiers in the reference datasets. For example, the
Set of homogeneous pieces of information from a professional viewpoint. A profession object is a shared concept in a data dictionary prepared by the National Service for Water Data and Reference-dataset Management (Sandre).
Aggregated data for human use. The National Service for Water Data and Reference-dataset Management (Sandre) produces information including in specification documents.
Data whose meaning has been functionally defined in detail as well as the rules for their creation (including possible values in some cases). Data dictionaries established by the National Service for Water Data and Reference-dataset Management (Sandre) include structured data.
