JEnsembl represents each of the database schema with a hierarchy of subclasses of the Database class, (CoreDatabase, ComparisonDatabase, VariationDatabase, etc).
Data related to sex, age, and place of residence were collated into an analysis database, with the following hierarchy: SINAN, SIM, then SISCEL.
The Integrating Network Objects with Hierarchies (INOH) database is a highly structured, manually curated database of signal transduction pathways including Mammalia, Xenopus laevis, Drosophila melanogaster, Caenorhabditis elegans and canonical.
The Integrating Network Objects with Hierarchies (INOH) database differs from other related pathway databases, such as Reactome (8), Nature Pathway Interaction Database (PID) (9), PANTHER (10), STKE (11), NetPath (12) and KEGG (13), in the following points (see Table 1 for a comparison of the INOH database with other publicly accessible signal transduction pathway databases).
These range from informal lists such as those used to categorize the articles in journals, through Nucleic Acids Research's hierarchies of database and Web-server categories (Benson, 2011; Galperin and Fernández-Suárez, 2012), to formal ontologies establishing commonly understood meaning and relations of subjects in focus.
Thus, we aimed to validate the CDS in patients with HF using Mokken scaling analysis (MSA), a method related to item response theory that analyses multivariate databases for unidimensional hierarchies of items [ 30].
Unfortunately, our suggestions for changes in publication standards will not solve the relationship of 'chemicals' in the reports to the specific organisms, as this would require some form of ontology or hierarchy in the database entries as well as in journal reports.
The hierarchy included which database the diagnosis came from, the provider type (e.g., psychiatrist vs. general practitioner), and the diagnoses itself (e.g., psychosis vs. conduct disorder).
Furthermore, our study also contrasts with an important implication of the earlier study, which advocated re-engineering the GO database by complementing the GO hierarchy with the links inferred from the functional linkage graphs [ 5].
There were occasional mistakes in how the review data had been entered into the hierarchy of the database, one common example being subgroups listed as if they were separate outcomes.
