Kerberos: An Authentication Service for Open Network Systems
- IN USENIX CONFERENCE PROCEEDINGS
, 1988
"... In an open network computing environment, a workstation cannot be trusted to identify its users correctly to network services. Kerberos provides an alternative approach whereby a trusted third-party authentication service is used to verify users’ identities. This paper gives an overview of the Kerb ..."

Deriving Production Rules for Incremental View Maintenance
- In Proceedings of the Seventeenth International Conference on Very Large Data Bases
, 1991
"... . It is widely recognized that production rules in database systems can be used to automatically maintain derived data such as views. However, writing a correct set of rules for efficiently maintaining a given view can be a difficult and ad-hoc process. We provide a facility whereby a user defines a ..."

Whom You Know Matters: Venture Capital Networks and Investment Performance,
- Journal of Finance
, 2007
"... Abstract Many financial markets are characterized by strong relationships and networks, rather than arm's-length, spot-market transactions. We examine the performance consequences of this organizational choice in the context of relationships established when VCs syndicate portfolio company inv ..."

. In essence, eigenvector centrality is a recursive measure of degree, whereby the centrality of an actor is defined as the sum of his ties to other actors, weighted by their respective centralities. Formally, let p ij be an indicator equaling one if at least one syndication relationship exists between VC i
Executing Queries over Schemaless RDF Databases
"... the Semantic Web have led to a rapid increase in both the quantity as well as the variety of Web applications that rely on the SPARQL interface to query RDF data. Thus, RDF data management systems are increasingly exposed to workloads that are far more diverse and dynamic than what these systems wer ..."

model, namely, schemaless-evaluation that leverages this workload-aware clustering of the database whereby, with high probability, each tuple in the result set of a query is expected to be contained in at most one cluster. Our query evaluation model exploits this property to achieve better performance
A general technique for querying xml documents using a relational database system
- SIGMOD Record
, 2001
"... There has been recent interest in using relational database systems to store and query XML documents. Each of the techniques proposed in this context works by (a) creating tables for the purpose of storing XML documents (also called relational schema generation), (b) storing XML documents by shreddi ..."

Quality Measuring in the Production of Databases
"... Quality, quality control and assurance, and especially quality management are becoming more and more important in using online information services. In this paper we will focus on the production of online bibliographic databases and discuss possible attributes responsible for the quality of this kin ..."

of this kind of online database. Starting with the acquisition of the original document, the quality of document analysis in the selection of the document, subject and bibliographical analysis are considered, whereby we give examples of how the quality attributes of the different productions steps may
Testing the relational Database
"... It is proposed that database systems be assessed for quality using an approach based on stochastic software testing. This approach requires an understanding of potential data errors ranging from syntactic mistakes to undetectable dirty data. A data error classification schema has been developed to c ..."

to categorize the type of data errors that could be found during testing. This classification schema provides a basis for developing test cases inclusive of data, constraints, rules, and supporting queries. A process is described whereby a database system is tested using the test cases and data validation
COSMOS: Our Database Vision
"... Object Storage System Concert is a long-term prototype development effort designed as a vehicle for our research activities in open storage management. Concert demonstrates key open features, including the ability to apply database functionality to externally-stored, externally-defined data. Concer ..."

-Object Storage Model [1]. This provides mechanisms whereby new implementations of the known Concert basic types can be embedded within the system, and hence existing database functionality applied to external objects. For example, a standard basic type construction for database systems is a record. Concert
Outline DISTRIBUTED DATABASE SYSTEMS

Universal Temporal Extensions for Database Languages

"... Temporal reasoning and temporal query languages present difficult research problems of theoretical interest and practical importance. One problem is the chasm between point-based temporal reasoning and intervalbased reasoning. Another problem is the lack of robustness and universality in many propos ..."

In this paper, we provide a simple solution to both problems by observing that all query languages support (i
