The heart of the business is in the data center. Companies cannot survive without running data centers. All business transactions are displayed there. One wrong step can be disastrous. So it is very important to have people to manage it. You have to be very efficient and very effective.
However, it should be noted that data access management does not depend on just one person. It's a collaboration of everyone in the data center. It's the whole team, not just the head. Apart from humans, the hardware is also important. So you need servers, proper storage, and resource requirements, as well as access control.
With a server, each database must have its server. Using one server for two databases is very dangerous for any business. If the server crashes, the company may not be able to survive and recovery will take a long time. Therefore, it is recommended that you share the features as soon as you start the project itself, rather than sharing them afterward. It's harder that way.
Having the right space and resource requirements is essential for managing a data center. All hardware and programs have their system requirements. You must be able to meet the requirements to maximize usage. Therefore, you need to consider space, power, and temperature requirements.
Access control is important because each user must have their limitations. No one should have full access unless that person is the boss or the person in charge of the whole project. This is to protect the company.
