Dataspaces are an abstraction in data management that aim to overcome some of the problems encountered in data integration system. The aim is to reduce the effort required to set up a data integration system by relying on existing matching and mapping generation techniques, and to improve the system in "pay-as-you-go" fashion as it is used. Labor-intensive aspects of data integration are postponed until they are absolutely needed.

Data integration
Data integration involves combining data residing in different sources and providing users with a unified view of these data. This process becomes significant in a variety of situations, which include both commercial (when two similar companies need to merge their databases) and scientific (combining research results from different bioinformatics repositories, for example) domains. Data integration appears with increasing frequency as the volume and the need to share existing data explodes.

Introspection
Introspection (or internal perception) is the self-examination of one's conscious thoughts and feelings. In psychology, the process of introspection relies exclusively on the purposeful and rational self-observation of one's mental state; however, introspection is sometimes referenced in a spiritual context as the examination of one's soul. Introspection is closely related to the philosophical concept of human self-reflection, and is contrasted with external observation.
