描述This book examines the recent trend of extending data dependencies to adapt to rich data types in order to address variety and veracity issues in big data. Readers will be guided through the full range of rich data types where data dependencies have been successfully applied, including categorical data with equality relationships, heterogeneous data with similarity relationships, numerical data with order relationships, sequential data with timestamps, and graph data with complicated structures. The text will also discuss interesting constraints on ordering or similarity relationships contained in novel classes of data dependencies in addition to those in equality relationships, e.g., considered in functional dependencies (FDs). In addition to exploring the concepts of these data dependency notations, the book investigates the extension relationships between data dependencies, such as conditional functional dependencies (CFDs) that extend conventional functional dependencies (FDs). This forms in the book a family tree of extensions, mostly rooted in FDs, that help illuminate the expressive power of various data dependencies. Moreover, the book points to work on the discovery of dep

Categorical Data, functional dependency (FD) . states that the same . values of two tuples imply their equal . values. Owing to the variety of issues in big data, data dependencies may not exactly hold. As indicated in [51, 139], the variety issue leads to constraints that may apply only to certain subsets of data.

Heterogeneous Data,address the variety issues of big data. Data obtained from merging heterogeneous sources often have various representation conventions. Dataspaces?[81, 91] provide a co-existing system of heterogeneous data from multiple sources. Carefully declared data dependencies over the heterogeneous data would

Ordered Data,ddress data dependencies on such ordered data. In the following, we introduce several typical studies on such ordered data, where each attribute . has a partial ordering . on .. Data dependencies are then declared concerning the orderings on the attribute domains [50, 83–85].
