Plug and Play: Interoperability in Concert

Abstract

Abstract. In order to make database systems interoperate with systems beyond traditional application areas a new paradigm called \exporting database functionality" as a radical departure from traditional thinking has been proposed in research a n d d e v elopment. Traditionally, all data is loaded into and owned by the database, whereas according to the new paradigm data may reside outside the database in external repositories or archives. Nevertheless, database functionality, s u c h as query processing, and indexing, is provided exploiting interoperability o f the DBMS with the external repositories. Obviously, there is an overhead involved having the DBMS interoperate with external repositories instead of a priori loading all data into the DBMS. In this paper we discuss alternatives for interoperability at di erent l e v els of abstraction, and we report on evaluations performed using the Concert prototype system making these cost factors explicit.

New Data Types and Operations to Support Geo-streams

“…Our work is closely related to spatio-temporal databases [8,11,17,12,9] and to a data type based spatio-temporal database approach [8,11,12] in particular. This approach focuses on designing spatio-temporal data types, operations, and predicates and embedding them into a query language to support the storage and query of spatio-temporal data.…”

“…Instead, most assume a complete view of the spatio-temporal phenomena without considering their streaming nature. Prototype spatio-temporal database systems, such as Concert [17], Secondo [12], and Dedale [9], have been built with various levels of support for spatio-temporal data.…”
