A method includes 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 a particular logical field selected via a database query interface. The data abstraction model includes a plurality of logical fields that each correspond to a particular data structure of the database. A web service input of a discovered web service is associated with a first logical field of the data abstraction model via the discovery registry, and a web service output of the discovered web service is associated with a second logical field of the data abstraction model via the discovery registry. A modified database query interface includes a text entry element to receive a text search term and a first selectable input associated with the first discovered web service.
