The major purpose of the design of distributed databases is to improve system performance and to increase system reliability. Fragmentation and allocation play important roles in the development of a cost-efficient system. This paper addresses the problem of fragmentation in the context of complex value databases, which cover the common aspects of object-oriented databases, object-relational da...

Cost estimation for Service Oriented Architecture (SOA) has not been addressed properly in the existing literatures. Most cost estimation approaches published in the literatures are more guidelines than actual practical estimation techniques. On the other hand, traditional software cost estimation techniques don’t fit SOA characteristics properly. In this paper, a phased effort distribution in ...

Service Oriented Enterprises (SOEs) are subject to constant change and variation. In this paper, the changes are considered from an economic perspective based on service culture notion. Once a change is implemented, the costs of some member services may increase, whereas the costs of some other services may reduce. We construct a game theoretic model trying to capture the possible conflicting i...

Quantifying and designing the cost pool generated by Business Intelligence and Analytics (BI&A) would improve cost transparency and invoicing processes, allowing a fairer, more exact allocation of costs to service consumers. Yet there is still no method for determining BI&A costs to provide a base for allocation purposes. While literature describes several methods for BI&A cost estimation on an...

     The present study investigated the use of interactive metadiscourse resources (IMRs) in terms of appropriacy during a process- based writing course by applying qualitative and exploratory methods. Moreover, learners' perception was investigated to find out how confident they felt as they were writing and rewriting the drafts. 30 intermediate EFL learners were chosen to participate in this ...
