Semantic Integration of Conceptual Schemes - Mirbel (Correct)
....real world that is examined. The first integration tools proposed were based on the relational model [BC86] on the entityrelationship model, the extended entity relationship model, and other semantic models [SJB92] Some research works on object oriented models have been published recently [TS94] Our approach is in line with this kind of works. Our goal was not to define a new object oriented model. So, we have built our integration process on the most often used notions [RBW 91, Bru91, Cas93] attribute, method, class, reference link, inheritence) Problemsand conflicts arise ....

An Open Approach for Data Integration - Boudjlida, Perrin (1995) (Correct)
....transform C maps the Instance Values of D 1 into Instance Values of D 2 . 3 In fact, the equivalence of two data type specications is more complex since it has to take into account the equivalence of the behaviour of the types (i.e. the equivalence between their respective sets of operations) [11, 24]. 4 It is also transitive and anti symetric : it denes a partial order among the types. 6 In this framework, the data integration process consists in the identication and the implementation of the transforms S and C. Concretely, S and C are sequences of atomic transforms of a data ....

Data Integration in a Legacy Systems Migration Process - Boudjlida, Bouneffa, Perrin (Correct)
....realises the comparison and the conformance phases. A set of hypothetical assumptions is generated from the examination of the data schema to integrate. The assumptions are possible similarities between two schema. Hypothetical assumptions are generated only on the basis of structural comparisons ([21] proposes similar mechanisms considering the behaviour of schema s objects) The assumptioms are rejected or con rmed in a user guided loop. Any con rmed assumption may trigger a change in one or in both of the schema. i) Transforming an attribute type into an entity type or into a subtype ....

Type Equivalence, Subtyping, and Type Transformations in.. - Thieme, Siebes Self-citation (Thieme Siebes) (Correct)
.... integration has been identified as one of the major challenges in responding to enterprises information requirements [9] In this report, we will prove a number of completeness results that are useful for semantic database integration, where databases are integrated using structure and behaviour [10, 11]. As a basis for the completeness results, we need a formalisation of both database schemas and database instances. A database schema in an object oriented database language (e.g. O 2 [8] or TM [3] is a class hierarchy: a set of classes related by a subclass relation. A class has a set of ....
