Amy S. Lee,Xuan Li,Li-jing Li,Edward Littles. We represent different kinds of database interactions, such as querying, constraint specification, updating, restructuring, and schema transformation, by means of a uniform graph-transformation framework based on pattern matching. Staying within the same framework, we incorporate viewing and give

Cell Biology and Pathology of Myelin clauses as rules in the database, not only Horn clauses or clauses with stratified negation. This allows to represent disjunctive information, in the database as well as in answers to queries. We utilize NF. relations for modelling sets of disjunctive facts and operations of the corresponding relat

Aida Selaru,Sorina Dinescu,Marieta Costache exists a single reason why the real world situations cannot be modeled adequately. What really is missing is a means to express that objects of a certain type are able to behave in a fashion objects of another type would do. To remedy this situation we introduce a single new concept, define its sem

Stem Cell Aging and Regenerative Medicine, that schemas are placed in a partial order that has bounded joins. This means that the merging operation, when it succeeds, is both associative and commutative, ., that the merge of schemas is independent of the order in which they are considered — a property not possessed by existing methods. The
