Research topics in statistical and scientific database management : The IV SSDBM,ion to the traditional topics (e.g., data model, physical organization and data retrieval, user interface and security) new topics emerged which appear to be growing in importance. Those include temporal data, statistical knowledge based decision support systems, geographical data and object oriente

The representation of a temporal data model in the relational environment,ather than an extension of one. This approach provided an insight into the special requirements for handling temporal data. In this paper, we discuss the implications of supporting such a model in the relational database environment. We show that the concept of a temporal relation needs to be introd

A study of modified interpolation search in compressed, fully transposed, ordered files, algorithm, presented in this paper, are combined to solve a conjunctive query search problem. The average complexity of the resulting method is analyzed, and the analytical performance model is compared with testbed experiments and an implementation in the Cantor system.

Design of statistical information media: Time performances and storage constraints,o optimize the time performance of the system it would be convenient to store the derived tables in secondary memory. However, a trade-off between storage resources and time performance arises: when the storage space is constrained, it is necessary to choose which derived tables have to be stored an

Handling time in query languages,rs by allowing their operands to be sets of intervals [BASS87]. The proposed temporal logic is shown to satisfy the properties of the normal Boolean logic. New syntax for retrieval statements is defined in order to separate the process of selecting entities (tuples) and the process of selecting requ
