Queries on Databases With User-Defined Functions
The notion of a database query is generalized for databases with user-defined functions. Then, we can prove that the computable queries coincide with those expressible by an extension of the relational machine, with oracles ([4]). This implies that any complete query language, extended with user-defined function symbols in a "reasonable" way, is still complete. We give an example of a complete ...
متن کاملSymbolic User-Defined Periodicity in Temporal Relational Databases
Calendars and periodicity play a fundamental role in many applications. Recently, some commercial databases started to support user-defined periodicity in the queries in order to provide “a human-friendly way of handling time” (see, e.g., TimeSeries in Oracle 8). On the other hand, only few relational data models support user-defined periodicity in the data, mostly using “mathematical” expressi...
متن کاملCuration accuracy of model organism databases
Manual extraction of information from the biomedical literature-or biocuration-is the central methodology used to construct many biological databases. For example, the UniProt protein database, the EcoCyc Escherichia coli database and the Candida Genome Database (CGD) are all based on biocuration. Biological databases are used extensively by life science researchers, as online encyclopedias, as...
متن کاملLiterature-driven Curation for Taxonomic Name Databases
Digitized biodiversity literature provides a wealth of content for using biodiversity knowledge by machines. However, identifying taxonomic names and the associated semantic metadata is a difficult and labour intensive process. We present a system to support human assisted creation of semantic metadata. Information extraction techniques automatically identify taxonomic names from scanned docume...
متن کاملSecure analysis of distributed chemical databases without data integration
We present a method for performing statistically valid linear regressions on the union of distributed chemical databases that preserves confidentiality of those databases. The method employs secure multi-party computation to share local sufficient statistics necessary to compute least squares estimators of regression coefficients, error variances and other quantities of interest. We illustrate ...
