Data Integration under Integrity Constraints

Data integration systems provide access to a set of heterogeneous, autonomous data sources through a so-called global schema. There are basically two approaches for designing a data integration system. In the global-centric approach, one defines the elements of the global schema as views over the sources, whereas in the local-centric approach, one characterizes the sources as views over the glo...

Integrity Constraints for Linked Data

Linked Data makes one central addition to the Semantic Web principles: all entity URIs should be dereferenceable to provide an authoritative RDF representation. URIs in a linked dataset can be partitioned into the exported URIs for which the dataset is authoritative versus the imported URIs the dataset is linking against. This partitioning has an impact on integrity constraints, as a Closed Wor...

Scheduling under Linear Constraints

We introduce a parallel machine scheduling problem in which the processing times of jobs are not given in advance but are determined by a system of linear constraints. The objective is to minimize the makespan, i.e., the maximum job completion time among all feasible choices. This novel problem is motivated by various real-world application scenarios. We discuss the computational complexity and...

Fixing Numerical Attributes Under Integrity Constraints

Consistent query answering is the problem of computing the answers from a database that are consistent with respect to certain integrity constraints that the database as whole may fail to satisfy. Those answers are characterized as invariant under minimal forms of restoring the consistency of the database. In this context, we study the problem of repairing databases by fixing numerical data at ...

FOL Modeling of Integrity Constraints (Dependencies)

DEFINITION Integrity constraints (also known as dependencies in the relational model) are domain-specific declarations which indicate the intended meaning of the data stored in a database. They complement the description of the structure of the data (e.g. in the relational model the structure is given by listing the names of tables and the names and types of their attributes). Integrity constra...
