Spatial join indices are join indices constructed for spatial objects. Similar to join indices for relational database systems, spatial join indices improve efficiency of spatial join operations. In this paper, a distanceassociated join index structure is developed to speed up spatial queries especially for spatial range queries. Three distance-associated join indexing mechanisms: basic, ring-s...

An increasing number of database queries are executed by interactive users and applications. Since the user is waiting for the database to respond with an answer, the initial response time of producing the first results is very important. The user can process the first results while the database system efficiently completes the entire query. The state-of-art join algorithms are not ideal for th...

Multipartner research, development and innovation (RD&I) projects are increasingly used to achieve complex goals keep pace with today's technological imperatives. The involvement of both competing noncompeting partners increases the complexity relationships poses a challenge outcomes such projects. Therefore, right choice is particularly important in this context. Although previous research has...
