Abstract
Lore (for Lightweight Object Repository) is a DBMS designed specifically for managing semistructured information. Implementing Lore has required rethinking all aspects of a DBMS, including storage management, indexing, query processing and optimization, and user interfaces. This paper provides an overview of these aspects of the Lore system, as well as other novel features such as dynamic structural summaries and seamless access to data from external sources.

The Web as a Resource for Question Answering: Perspectives and Challenges

TL;DR: Analysis of real-world user questions reveals that the federated and distributed approaches complement each other nicely, suggesting a hybrid approach in future question answering systems.

Pushing reactive services to XML repositories using active rules

TL;DR: This paper proposes the new concept of active XML rules for ‘‘pushing’’ reactive services to XML-enabled repositories and capitalizes on the use of standard DOM events and of the SOAP interchange standard to enable the remote installation of active rules.

Views for Semistructured Data

TL;DR: This paper proposes a view specification language and considers the problem of answering queries posed over views, with focus on the diffcult problems caused by the semistructured nature of the data.

The Michigan benchmark: towards XML query performance diagnostics

TL;DR: A micro-benchmark for XML data management is proposed to aid engineers in designing improved XML processing engines, and finds that commercial relational techniques are effective for XML query processing in many cases, but are sensitive to query rewriting, and require better support for efficiently determining indirect structural containment.

A basis for a visual language for describing, archiving and analyzing functional models of complex biological systems

TL;DR: Given available computer and internet technology, BioD may be implemented as an extensible, multidisciplinary language that can be used to archive functional systems knowledge and be extended to support both qualitative and quantitative functional analysis.

Federated database systems for managing distributed, heterogeneous, and autonomous databases

TL;DR: In this paper, the authors define a reference architecture for distributed database management systems from system and schema viewpoints and show how various FDBS architectures can be developed, and define a methodology for developing one of the popular architectures of an FDBS.

Query evaluation techniques for large databases

TL;DR: This survey describes a wide array of practical query evaluation techniques for both relational and postrelational database systems, including iterative execution of complex query evaluation plans, the duality of sort- and hash-based set-matching algorithms, types of parallel query execution and their implementation, and special operators for emerging database application domains.

DataGuides: Enabling Query Formulation and Optimization in Semistructured Databases

TL;DR: The theoretical foundations of DataGuides are presented along with an algorithm for their creation and an overview of incremental maintenance, and performance results based on the implementation of dataGuides in the Lore DBMS for semistructured data are provided.

The Lorel Query Language for Semistructured Data

TL;DR: The main novelties of the Lorel language are the extensive use of coercion to relieve the user from the strict typing of OQL, which is inappropriate for semistructured data; and powerful path expressions, which permit a flexible form of declarative navigational access and are particularly suitable when the details of the structure are not known to the user.
