1. A computer-implemented method, comprising: receiving a selection of a particular logical field via a database query interface; querying a discovery registry associated with a data abstraction model of a database to discover one or more web services that are resolvable based on the particular logical field, wherein the data abstraction model includes a plurality of logical fields, wherein each logical field of the plurality of logical fields corresponds to a particular data structure of the database, wherein a web service input of a particular discovered web service is associated with a first logical field of the data abstraction model via the discovery registry, and wherein a web service output of the particular discovered web service is associated with a second logical field of the data abstraction model via the discovery registry; automatically initiating execution of the one or more discovered web services; and displaying one or more values resulting from execution of the one or more discovered web services.
