Queries and Query Execution Plans

This section describes the queries that have been (or are to be) implemented for the Phenoscape data services, in addition to the execution details of each queries on the PostgreSQL database on Darwin.

Database details

Anatomical Entity Services

Using LIKE Wildcard Operator

This query will return all the PHENOTYPES that inhere in a ANATOMICAL ENTITY* and the subclasses of the ANATOMICAL ENTITY*. In addition, all the QUALITIES that are related to each PHENOTYPE are returned. The SUBSET SLIMS of each QUALITY are returned. Finally, all the TAXA that exhibit the PHENOTYPES are returned.

• Search Term (The search term in this example is TAO:0000108, which is, you guessed it, a fin!)

Using LIKE Wildcard operator and a restriction on Slims returned

This query will return all the PHENOTYPES that inhere in a ANATOMICAL ENTITY and the subclasses of the ANATOMICAL ENTITY. In addition, all the QUALITIES that are related to each PHENOTYPE are returned. Only those QUALITIES which are either ATTRIBUTE_SLIMS or VALUE_SLIMS are returned. Finally, all the TAXA that exhibit the PHENOTYPES are returned.

Using EQUALS (=) Operator

The result of this query is the same as for the previous two queries except the wildcard search is replaced by exact match requirements on the search parameters viz. relation and concept names (IDs, to be specific). This enables leverage of the indexes set up for the Link and Node tables in the OBDPhenoscape database
