關於這本有聲書

Are you interested in getting a better understanding of the COBOL programming language?

Do you seek to know how COBOL interacts with other database management systems?

Would you like to expand your knowledge base of database systems?

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, preexisting 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.

Why is it necessary to understand COBOL database interaction?

Understanding the basics of COBOL database interaction is essential in the technology field because COBOL has been used in many industries and is still in use today. In addition, this knowledge can be applied to many software applications and programs.
