Care-Oriented Data Systems

Recovery Management and Recovery-Oriented Systems of Care.

Patient data management systems in critical care.

Electronic patient data management systems (PDMS) were clinically used for the first time in the 1970s. Their purpose was to automatically document vital parameters sampled by monitors and to replace handwritten medical files. Because of the continuous development of computer technology, however, demands on PDMS have increased immensely. PDMS are currently expected to assist clinicians at every...

Data Modeling for Ambient Home Care Systems

Ambient assisted living (AAL) services are usually designed to work on the assumption that real-time context information about the user and his environment is available. Systems handling acquisition and context inference need to use a versatile data model, expressive and scalable enough to handle complex context and heterogeneous data sources. In this paper, we describe an ontology to be used i...

Management of Data Model Evolution in Object-Oriented Database Systems

Object-oriented database systems are designed to meet the requirements of advanced database applications. These requirements may evolve in the course of time and must be managed consistently at all levels of abstraction of a database system the database level, the database schema level, and the data model level. Approaches to the management of changes at the database level and the database sche...

Goal-oriented dynamic buffer pool management for data base systems

This paper presents a technique for performing dynamic goal oriented buuer pool management for database management systems. To dynamically adjust the buuer pool sizes for the multiple buuer pools provided by database management systems is a complex constrained optimization problem. In the goal oriented approach, the user speciies each buuer pool's random access response time goal and the total ...
