Cobol: Cobol Database Interaction by Andy Vickler
Requirements: .ePUB reader, 2 MB
Overview: COBOL Database Interaction is a set of techniques that allow us to interact with databases. COBOL Database Interaction is used to retrieve, store and modify specific records in a database table. It is done by modifying row values. This feature of COBOL allows us to perform everyday tasks such as deleting or updating records in a database table while restoring the original state of the data after the updated records have been deleted.
COBOL Database Interaction is used to update records in a database table selectively. It is done by modifying row values without affecting other records in the same table. COBOL Database Interaction allows us to perform tasks such as deleting or updating specific, pre-existing records and also provides us with a mechanism by which we can create new, empty records (without having to create them manually) before saving them to their original data tables.
