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

Data manipulation in an XML‐based digital image library
TL;DR: It is demonstrated that, although XML itself is not a database, the XML family provides many, though not all, of the components found in the database systems found in relational databases.

Dynamic re-configurable transaction management in AgentTeam
TL;DR: The design of DDBM in form of a multi-agent system of the AgentTeam framework is discussed, particularly the dynamic reconfigurable transaction management model, and the CourseMan prototype is described, which is implemented inform of a test-bed that provides a homogeneous environment for testing different D DBM protocols, upon heterogeneous DBMSs.

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.
