move this application to OCI and they want to use a managed database offering for their database tier.

B. A midsize company is considering migrating its legacy on-premises MongoDB database to Oracle Cloud
Infrastructure (OCI). The database has significantly higher workloads on weekends than weekdays.

C. A small startup is deploying a new application for eCommerce and it requires a database to store
customers’ transactions. The team is unsure of what the load will look like since it is a new application.

D. A well-established, online auction marketplace is running an application where there is database usage

may reach 3 times the normal activity level.

E. A developer working on an internal project needs to use a database during work hours but doesn’t need it
during nights or weekends. The project budget requires her to keep costs low.
