Sync your data: update propagation for heterogeneous protein databases

The traditional model of bench (wet) chemistry in many life sciences domain is today actively complimented by computer-based discoveries utilizing the growing number of online data sources. A typical computer-based discovery scenario for many life scientists includes the creation of local caches of pertinent information from multiple online resources such as Swissprot [BA00], PIR [BGH+ 00], PDB [PDB03], to enable efficient data analysis. This local caching of data, however, exposes their research and eventual results to the problems of data staleness, that is, cached data may quickly be obsolete or incorrect, dependent on the updates that are made to the source data. This represents a significant challenge to the scientific community, forcing scientists to be continuously aware of the frequent changes made to public data sources, and more importantly aware of the potential effects on their own derived data sets during the course of their research. To address this significant challenge,...
