Data on extant and fossil corals are analyzed. The characteristics of the organisms are divided into five basic units of data: morphology, ecology, taxonomical relations, stratigraphical, and (paleo-) geographical occurrence. Six data complexes are derived from these units. Their relationships are defined and the database structures designed on the basis of the Entity-Relationship-Model. The data structures are described in detail and advice is given for building up databases. The various opportunities of querying the database and particularly of assessing the data are thoroughly discussed. Data obtainable by transactions on the stratigraphical and (paleo-) geographical distribution of the organisms are considered. Finally, the database on Mesozoic corals compiled by the author is introduced and some preliminary results as well as future projects are presented.
