Transforming Databases With Recursive Data Structures
- …TRANSFORMING DATABASES WITH RECURSIVE DATA STRUCTURES Anthony Kosky Advisors: Susan Davidson and Peter Buneman. This thesis examines the problems of performing structural transformations on databases involving complex data-structures and object-identities, and proposes an approach to specifying a…

Observational Distinguishability of Databases with Object Identity
- …We will examine the problem of distinguishing between database instances and values in models which incorporate object-identities and recursive data-structures. We will show that the notion of observational distinguishability is intricately linked to the languages available for querying a database. …

A Formal Model for Databases with Applications to Schema Merging
- …In this paper we present a simple and general model for database schemas and their instances. The model is sufficiently expressive to represent complex, higher order data structures and incorporates representations for specialisation relations and object identity. It is general enough to encode data…

Modeling and Merging Database Schemas
- …this paper we will construct and investigate various aspects of a new, formal model for database structures. In particular we will concentrate on providing a general model for database schemas which will be basically functional ([HK87]), and will support specialisation relationships. Wherever possib…

Types with Extents: On Transforming and Querying . . .
- …The central theme of this paper is to study the properties and expressive power of data-models which use type systems with extents in order to represent recursive or selfreferential data-structures. A standard type system is extended with classes which represent the finite extents of values stored i…

Seamless integration of biological applications within a database framework
- …There are more than two hundred biological data repositories available for public access, and a vast number of applications to process and interpret biological data. A major challenge for bioinformaticians is to extract and process data from multiple data sources using a variety of query interfaces …

Semantics of Database Transformations
- …Abstract. Database transformations arise in many di erent settings including database integration, evolution of database systems, and implementing user views and data-entry tools. This paper surveys approaches that have beentaken to problems in these settings, assesses their strengths and weaknesses…

Constructing and Maintaining Scientific Database Views in the Framework of the Object-Protocol Model
- …Scientific databases (ScDBs) are used to archive and retrieve data describing objects of scientific inquiry. Since these ScDBs must provide continuous and efficient access to large communities of scientists, they are often developed with reliable commercial relational database management systems (DB…

Facilities For Exploring Molecular Biology Databases On The Web: A Comparative Study
- …this paper, we discuss criteria for evaluating the main facilities required for exploring MBDs on the Web, that is, retrieving and interpreting MBD metadata and data. We apply these criteria in comparing the main facilities provided by typical MBDs, such as Genbank, AtDB, GSDB, GDB, and MGD. These …
