The present disclosure generally relates to database modification, and in particular, database modification in the context of networked platforms accessible by user computing devices. One example context to which such database modification techniques can be applied is a network provider providing a plurality of individual network portals via which users may access network resources and perform other transactions. Such a network provider may maintain a network resource availability database that needs to be updated in response to each network resource access requests being received and granted via the plurality of individual network portals. The techniques described herein allow the network resource availability database of such a network provider to be updated differently depending on the context in which resource requests are granted.
