Bridging objects with logical rules: towards object oriented deductive databases,ems from two arguments; on one hand, object-orientation brings powerful data modeling capabilities by adding semantic and structural complexity to value-based relational databases. On the other hand, logic programming languages provide means for expressing queries and updates on a database with a de

The LOGIDATA+ model,ons (value based), and functions. Classes can be referred to in relations and functions. Is-a relationships can be defined on classes. Complex values can be built by means of the recursive use of set, tuple, and sequence constructors. As usual in database frameworks, the model has an intensional lev

The LOGIDATA+ language and semantics,and data functions. Negation is allowed in the body of rules. The semantics is based on a fixpoint operator and represents an extension of ordinary declarative-language semantics. The main issue is the management of oid-invention, that is, the creation and manipulation of objects belonging to the cl

Travel agency: A LOGIDATA+ application,s concerned with the construction of travels on the basis of the clientś specifications. The program queries the database and generates a report with all the available choices in terms of transfers and accomodations. The scheme and the clauses use a wide range of language functionalities, as complex

Management of extended update operations,ors are introduced, which correspond to basic manipulations of complex data entities with object identity. These operators can be used in rules bodies for specifying complex update transactions. The resulting language is first informally presented by using several examples. Then, the syntax and the

Taxonomic reasoning with cycles in LOGIDATA+,, which extends LOGIDATA. to perform taxonomic reasoning in the presence of cyclic class definitions is introduced. It includes the notions of . of a schema; . of a schema, defined as the . fixed-point of possible instances; .. On the basis of this framework, the definitions of . and . are introduce
