The prominent role played by women’s empowerment and multidimensional poverty reduction in the development process is justified including Goal-1 Goal-5 under 2030 agenda of UNDP’s Sustainable Development Goals. This study examines nexus between rural areas Jagatsinghpur district Odisha. Alkire-Foster method used to construct Women Empowerment Index Multidimensional Poverty Index. Education, hea...
As one of the most important technology for implementing large-scale distributed systems, peer-to-peer (P2P) computing has attracted much attention in both research and academia communities, for its advantages such as high availability, high performance, and high flexibility to the dynamics of networks. However, multidimensional data indexing remains as a big challenge to P2P computing, because...
Many applications require data base systems with the capability to manage large amounts of data and to answer complex queries, especially those with several attributes, such as range queries and more particularly, spatial and temporal queries. Consequently, new access methods, with good performance for these types of operations associated with medium-high dimensionality, are needed. From this p...
It is commonly accepted in the practice of on-line analytical processing databases that the multidimensional database organization is less scalable than the relational one. It is easy to see that the size of the multidimensional organization may increase very quickly. For example, if we introduce one additional dimension, then the total number of possible cells will be at least doubled. However...
We examine the European Union (EU) countries and within-country areas (i.e., large urban areas, small urban areas, and rural areas) that are the most disadvantageous with respect to multidimensional poverty and in each of the investigated dimensions, i.e., health, education, and living standards. To this end, we construct the Multidimensional Poverty Index and its sub-indices: the Poverty in He...
A new issue that arises in modern applications involves the efficient manipulation of (static or moving) spatial objects, and the relationships among them. As a result, modern database systems should be able to efficiently support that type of data. Towards this goal, appropriate extensions of multidimensional access methods can be exploited in order to index and retrieve spatiotemporal objects...
This paper proposes a multidimensional index that summarizes three relevant aspects of the educational achievements, out of the data provided by the PISA Report, concerning reading abilities of 15-year-old students from 65 countries. The three aspects considered are: performance, equity, and quality. The Educational Development Index (EDI) is the geometric mean of the normalized values of those...
Multidimensional access methods like the UBTree can be used to accelerate almost any query processing operation, if proper query processing algorithms are used: Relational queries or SQL queries consist of restrictions, projections, ordering, grouping and aggregation, and join operations. In the presence of multidimensional restrictions or sorting, multidimensional range query or Tetris algorit...
In emerging analytical database applications that deal with large sets of multidimensional static data sets, the performance of the query system significantly depends on the performance of its access methods and the underlying disk system. In recent years, hard disks are manufactured with multiple physical zones, where seek times and data transfer rates vary significantly across the zones. Howe...
In existing database systems there is a strong need for searching data according to many attributes. In commercial database platforms, the standard search over multiple attributes is provided by B-tree (or it’s variants) with compound keys. On the other hand, such systems provide also multidimensional indexing, however, just for spatial purposes (such as GIS or CAD applications) and use special...
