- You have been given the task of documenting the process and commands required for creating a new user and assigning privileges to that user for one or more of the tables in a DBA’s practice database layout below. This process will be documented schematically in the table below that will: - identify all SQL commands (using proper role names, table names, user names, etc. and proper syntax), - identify which user (DBA or NEW USER) should execute each command, and - detail the expected outcome based on your knowledge of Oracle data administration, roles, and granting and revoking privileges to roles. Initially, the new user will not be able to do anything, including any selects, inserts, updates, or deletes on any of the DBA’s tables. The DBA will create a role and assign the new user to that role. Then, the DBA will grant and revoke various select, insert, update or delete privileges to the role. It is your responsibility to determine the outcome. You will not be able to execute…arrow_forwardBriefly explain the importance of conceptual or internal mapping in DBMSarrow_forwardYou can select more than one optionarrow_forward

How do they differ from one another?arrow_forwardAll the following are true with respect to surrogate keys EXCEPT one. Which of the following is NOT true of surrogate keys?

- A software package to implement a data base is DBMS explain?arrow_forwardTopic: Database Design It is known that can use the DBMS system to create a surrogate primary key when there is a natural key. What implications does this have on the DB performancewhen searching the table for a specific column (such as ROOM). Hint: When the table is created, the DBMS setups the table to be able to search on the primary key very quickly. What if this Event table was used by a Corporate Hotel chain to keep track of every they have hosted over the past 30 years in all of their hotels across all their chains (i.e. 8000 locations, 5 events a week avg, 30 years of data ~62.4 million events)?arrow_forwarddescribe the subsequent sections are the foundation for the physical data structures used by most relational DBMSsarrow_forward

ManagerEmpNo identifies the employee who is the Manager of the department. There is only one Manager for each department. Project contains details of the projects in each department. No two departments can run the same project. WorksOn contains details of the hours worked by each employee on each project.
