managed locally. The Local management table space is managed through bitmaps.Autoallocate indicates that the table space is automatically assigned a range, and the user cannot specify the size of the range. Only more than 9.0 of the versions have this feature.The uniform indicates the fixed size of the table space's range, which is 1m by default.You cannot set the system table space of a locally administered database to dictionary management.Oracle recommends using local management table spaces

Let's assume that I only want user BOB to see the ENAME and DEPNO columns in the EMP table. I can use the following:GRANT select ON emp TO bob; However, the above command will show BOB all the contents of the table. I can write down the following view so that BOB can only see the columns that he

It is generally used in places where the sequence numbers need to b

they cannot access other data in the base table. You can make data independent of your application. (This allows for the independence of the data) so that the same data appears in different views in different forms. For example, for each user to create a different view, each user sees the same data, but the column name, the view name may be different.
