ER - TY - CONF AB - Semantic data models have been widely studied for the conceptual specification of databases. However, most of these data models are restricted to the description of the static structure of a database. They do not provide means to specify the dynamic behaviour of a database. This paper sketches a language for the specification of actions on databases which have been specified by an Extended Entity-Relationship (EER) schema. These actions are based on so-called elementary actions, which are automatically be derived from the EER schema. So, it can always be guaranteed that these schema dependent elementary actions preserve all inherent integrity constraints. The semantics of the elementary actions is given in two steps: First, it is shown how the semantics of a database schema, i.e., a current database state, can be represented by an attributed graph. Then, the semantics of elementary actions is given by programmed graph replacements.

This constraint is met by double-spaced run-length-limited (d, k, 2) codes where the number of consecutive zeros is even. Exploiting the polarity of the transitions, a detection window that has double the size of the code bit period is possible. The authors describe a detection circuit that achieves the enlarged detection window, and present a phase detector which is particularly simple to implement. Channel bit-error-rate measurements have been carried out employing a rate 1/3 (2, 8, 2) code. Error rates of 10/sup -8/ were achieved for recording densities up to 33 kb/in. The results demonstrate the expected excellent immunity of the direct overwrite scheme to bloom. AU - Haeb-Umbach, Reinhold AU - Rugar, D. AU - Howell, T. AU - Coleman, G. P.
