The
mongodb vocabulary provides two different interfaces to the MongoDB document-oriented database
Low-level driverThe
mongodb.driver vocabulary provides a low-level interface to MongoDB.
USING: mongodb.driver ;
"db" "127.0.0.1" 27017 <mdb>
[ "mycollection" [ H{ { "name" "Alfred" } { "age" 57 } } save ]
[ "ageIdx" [ "age" asc ] key-spec <index-spec> ensure-index ]
[ H{ { "age" H{ { "$gt" 50 } } } } <query> find-one ] tri ] with-db
Highlevel tuple integrationThe
mongodb.tuple vocabulary lets you define persistent tuples that can be stored to and retrieved from a MongoDB database
USING: mongodb.driver mongodb.tuple fry literals ;
MDBTUPLE: person name age ;
person "persons" { } { $[ "ageIdx" [ "age" asc ] key-spec <tuple-index> ] } define-persistent
"db" "127.0.0.1" 27017 <mdb>
person new "Alfred" >>name 57 >>age
'[ person ensure-table _ save-tuple person new 57 >>age select-tuple ] with-db
