Supporting annotations on relations
Annotations play a key role in understanding and curating databases. Annotations may represent comments, descriptions, lineage information, among several others. Annotation management is a vital mechanism for sharing knowledge and building an interactive and collaborative environment among database users and scientists. What makes it challenging is that annotations can be attached to database entities at various granularities, e.g., at the table, tuple, column, cell levels, or more generally, to any subset of cells that results from a select statement. Therefore, simple comment fields in tuples would not work because of the combinatorial nature of the annotations. In this paper, we present extensions to current database management systems to support annotations. We propose storage schemes to efficiently store annotations at multiple granularities, i.e., at the table, tuple, column, and cell levels. Compared to storing the annotations with the individual cells, the proposed schemes ac...
