A relatively small team of people who collaborate on the same project is called a(n): A) 1950s. Minimizing name changes simplifies the migration of databases from one environment to another. Development starts from scratch with the traditional file processing approach because new file formats, descriptions, and file access logic must be designed for each new program. To ensure the success of the migration, the DBA should document the methods used for the migration and record the verification process.
