Database scale-out is commonly implemented by partitioning data across several database instances. This approach, however, has several restrictions. In particular, partitioned databases are inflexible in large-scale deployments and assume a partition-friendly workload in order to scale.

Modern data-centric flows in the telecommunications industry require real time analytical processing over a rapidly changing and large dataset. The traditional approach of separating OLTP and OLAP workloads cannot satisfy this requirement. Instead, a new class of integrated solutions for handling hybrid workloads is needed. This paper presents an industrial(More)
In this paper we present a prototype Javascript-based client-side W3C XML<lb>Schema validator, together with an API supporting online interrogation of<lb>validated documents. We see this as enabling an important improvement in<lb>XML-based client-side applications, extending as it does the existing datatype-<lb>only validation provided by XForms to(More)
