For the design, construction, integration and installation of the LHC, the LHC Layout database manages the information on the functional positions of the components of the LHC. Since January 2005, the scope of this database has been extended to include all electronics racks in the tunnel, underground areas and surface buildings. This description of the accelerator and the installed controls top...

Researchers at the Geoengineering and Mineral Processing Study Centre of the Italian Research Council, have developed a database system integrated with a GIS (Geographical Information System),jor data collection on operational or closed waste disposal sites. This paper describes the objectives of the system, the data organisation, the structure of the database, the characteristics and functiona...

The Storm Prediction Center (SPC) maintains an internal database of observational soundings from the contiguous United States (CONUS), dating back to the 1940s and 1950s for many sites. This database has been the source of extensive development in both research and operational forecasting over the past several decades. Previous studies utilizing this database have primarily focused on individua...

The BaBar experiment stores its data in an Object Oriented federated database supplied by Objectivity/DB(tm). This database is currently 350TB in size and is expected to increase considerably as the experiment matures. Management of this database requires careful planning and specialized tools in order to make the data available to physicists in an efficient and timely manner. We discuss the op...

A computerized clinical database is a collection of organized clinical data, created to store, retrieve, analyze, and report meaningful information (McCartney & Barnes, 2012). In today’s datadriven healthcare system, effi cient access to clinical database information is necessary for decisionmaking, managing care, conducting research, performance improvement, and reporting. Three general types ...

A seamless approach to the incremental design and reuse of object-oriented methods and query specifications is presented. We argue for avoiding or minimizing the effort required for manually reprogramming methods and queries due to schema modifications, and demonstrate how the role of polymorphic reuse mechanisms is exploited for enhancing the adaptiveness of database programs against schema ev...

The execution logs that are used for process mining in practice are often obtained by querying an operational database and storing the result in a flat file. Consequently, the data processing power of the database system cannot be used anymore for this information, leading to constrained flexibility in the definition of mining patterns and limited execution performance in mining large logs. Ena...

Many real-time database systems are now being used in safety-critical applications, in which human lives or expensive machinery may be at stake. Transactions in real-time databases should be scheduled considering both data consistency and timing constraints. In addition, a real-time database must adapt to changes in the operating environment and guarantee the completion of critical tasks. The e...

Transactions in real-time database systems should be scheduled considering both data consistency and timing constraints. In addition, a real-time database must adapt to changes in the operating environment and guarantee the completion of critical tasks. The effects of scheduling decisions and concurrency control mechanisms for real-time database systems have typically been demonstrated in a sim...
