TLDR
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.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.read more

Magnet: supporting navigation in semistructured data environments
Vineet Sinha,David R. Karger +1 more
TL;DR: A general-purpose tool is developed that offers users helpful navigation and refinement options for seeking information in semistructured repositories, and it is shown how a tool can be built without requiring domain-specific assumptions about the information being explored.

Modeling and Transformation of Object-Oriented Conceptual Models into XML Schema
TL;DR: This paper presents the way to model XML and to transform the Object Oriented (OO) conceptual model into XML Schema, and several generic transforming rules from the OO conceptual model to XML schema, with the emphasis on the transformations of generalization and aggregation relationships.

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.

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.
