Many important business applications use complex database management systems (DBMS). These DBMS have to be administrated and optimized for an optimal performance, especially in time-critical applications. Administration and optimization are very complex and costly tasks. Therefore, researchers and DBMS vendors focus on development of self-tuning techniques for a continuous adaption, e.g., the C...

Using magnetic disks as a cache for tertiary storage has been shown to be an effective way to address the high storage costs of large-scale multimedia servers. We investigate a technique for managing the bandwidth of such a hierarchical storage design. In existing schemes, all data items are treated equally; and the same I/O rate is used to load data from tertiary storage when they are requeste...

In algorithm management, data are distributed in accordance with a data distribution algorithm that is capable of determining, on the basis of the datum ID, the node in which the required data is being stored. Among the requirements for a data distribution algorithm are short calculation times, low memory consumption, uniform data distribution in accordance with the capacity of each node and th...

The improving resolution of remote sensing (RS) images is causing the amount of data in such images to increase with a geometric progression. A very large application system can now contain terabytes, even petabytes. Furthermore, these large quantities of data are generally dispersed in different places for storage. Research on how to store and manage massive distributed RS images is vital. Thr...

The principles and strategies found in material management are comparable and analogue with the data management. This paper concentrates on the conversion of product inventory management principles into data inventory management principles. Efforts were made to enumerate various impacting parameters that would be appropriate to consider if any data inventory model could be plotted. The inventor...

The proper management of oily sludge from petroleum products storage tanks is necessary because inappropriate methods for dredging of tanks may result in high costs and increased environmental pollution. The purpose of the current study is to rank the strategies outlined by strengths, weaknesses, opportunities and threats analysis using data envelopment analysis model, which provides enriched i...

background: personal information management (pim) refers to the tools and activities to save and retrieve personal information for future uses. this study examined the pim activities of faculty members of iran university of medical sciences (iums) regarding their preferred pim tools and four aspects of acquiring, organizing, storing and retrieving personal information.   methods : the qualitati...

There is a wealth of research on storage systems, focusing on the storage system architecture, intelligent use of storage resources, and mass storage systems. However, very little research looks at a key component of centralized storage systems, the physical fabric of the network that holds the storage system together. “Best practice” frameworks for the management of storage systems exist, but ...

Being sustainable and producing little waste products, the renewable energy knows a rapid deployment. Unfortunately, the intermittent characteristic of these energies makes them difficult to control. The influence of this aleatory character can be reduced with the coupling of two or more sources of renewable energy and secondly with a sound management of storage systems. This new configuration ...
