Open AccessAn online model composition tool for system biology models
There are multiple representation formats for Systems Biology computational models, and the Systems Biology Markup Language (SBML) is one of the most widely used. SBML is used to capture, store, and distribute...

Open AccessEfficient path-based computations on pedigree graphs with compact encodings
A pedigree is a diagram of family relationships, and it is often used to determine the mode of inheritance (dominant, recessive, etc.) of genetic diseases. Along with rapidly growing knowledge of genetics and ...

XML Restructuring and Integration for Tabular Data
We study the data integration and restructuring issues of tabular data. We consider the case where the same set of data is collected from independent sites, stored in different DBMSs or other repositories, org...

Maintenance of implication integrity constraints under updates to constraints
Semantic integrity constraints are used for enforcing the integrity of the database as well as for improving the efficiency of the database utilization. Although semantic integrity constraints are usually muc...

Extended set operators for nested relations and complex objects
Extended set operators defined originally for nested relations form a basis for the set operators for complex objects because the common approach based on the application of set operators to sets of oids (base...

On the maintenance of implication integrity constraints
Semantic integrity constraints are utilized for enforcing the integrity of the database as well as for improving the efficiency of the database utilization, as in semantic query optimization. In this paper we ...

On efficient reasoning with implication constraints
In this paper, we address the complexity issue of reasoning with implication constraints. We consider the problem of deciding whether a conjunctive yes/no-query always produces the empty relation (“no” answer)...

Meta Variables and Inheritance in an Object-Oriented Data Model
In this paper, we discuss the properties of an object-oriented data model that combines the simplicity of relational data model and features of object-oriented data models. Meta variables are introduced for in...

On the normalization in Nested Relational Databases
In this paper, we address the problem of designing a database with nested relations with respect to semantic integrity constraints. The semantic integrity constraints we consider are functional and multivalued...

A Query Language for Statistical Databases
In this chapter we describe a high level, screen-oriented database query language, Summary-Table-by-Example (STBE) for manipulating summary data in statistical databases. STBE uses aggregate functions, relatio...
