The four functions that database management systems perform on data residing in a database are: create data, serach data, update data, and delete data.
Database management systems are software systems that allow the creation and management of a massive amount of data. Database management systems offer various functions. Out of all the four basic functions include:
Create data: This function of the database management system permits the storage of large amounts of data in a single system; every data item has a unique identity.Search data: This function of the database management system helps to find any specific record or data item within a second from the database.Update data: Data in a database requires updates regularly or occassionly. This function of the database management system allows to update the data with the latest information, whenever needed.Delete data: If it seems that data is no longer in use; the delete function of the database management system makes it easier to delete the specified data.You can learn more about database management system at

what tool can be used to map out all the roles and responsibilities that will be needed to set up an access control model?
Org chart, information management model, access control list, identity management process can be used to map out all the roles and responsibilities that will be needed to set up an access control model.
What are the access control method?
Access control systems are one of the most important resources in a business and are highly valuable. Access control is defined as "the control of access to system resources following the authentication of a user's identity and account credentials and the granting of access to the system." Access control is used to recognize a subject (user or human) and provide that subject permission to access a resource or piece of data in accordance with the task at hand. These measures are taken to ensure that only secure and pre-approved methods can be used by subjects to access resources, protecting them from unwanted access.
What are the types of access control?
1)Discretionary Access Control (DAC)
In comparison to other forms of access control, DAC systems are thought to be the most adaptable and to provide the greatest number of permissions. The most flexible form also has the lowest level of security, especially when compared to systems that require access control and usability.
2) Mandatory Access Control (MAC)
Mandatory access control systems (MAC), on the other hand, are the most secure kind of access control. The only people who can use the systems are owners and custodians. The system administrator has predetermined all access control settings, and they cannot be altered or removed without that administrator's consent.
3)Role-Based Access Control (RBAC)
The most common kind of access control is quickly evolving into role-based access control (RBAC). An RBAC system operates by granting permits to a certain job title rather than issuing them to specific people as in a MAC system. It reduces the amount of time needed to set up or modify user access.
4)Rule-Based Access Control
Rule-based access control, which should not be confused with the other "RBAC," is frequently used as an addition to the other types of access control. In addition to the access control type you select, rule-based access control can modify permissions in accordance with a particular set of rules that the administrator has established.
