The object that must be unique in each schema is the primary key. The primary key is a unique identifier for each record in a database table, ensuring that each row is uniquely identifiable. This uniqueness helps maintain data integrity and allows for efficient retrieval of specific records.
The computer's MAC address must be unique, and the internal IP address must be unique. Either of these being the same as another computer's causes issues which won't let your computer connect.
1.each row must have unique(pk)in a relation. 2.database must have a unique name. 3.each column must have unique name.
Either an administrator or a member of the administrators group. ^^^^^ Administrators must be given explicit permission or be a member of the Schema Administrators group to make changes to the schema. ^^^^^
Object B must be circumscribed about object A.
.Object B must be inscribed in object A.
objectGUID property unique security identifiers (SIDs) Each object represents a single entity-whether a user, a computer, a printer, or a group-and its attributes. Certain objects can contain other objects. An object is uniquely identified by its name and has a set of attributes-the characteristics and information that the object represents- defined by a schema, which also determines the kinds of objects that can be stored in Active Directory.
A user in Oracle corresponds to a schema. Objects, such as table and indexes, must exist within a schema. Without creating a user/schema, use of the database will be limited to the built-in schemas and objects, such as the one-row DUAL table and standard PL/SQL packages.
A restriction for a table to be a relation is that it must have a unique name and each column must have a unique name. Additionally, each cell in the table must hold a single value from the same domain, and the order of rows and columns should not matter.
For an object to be at equilibrium, the net force acting on it must be zero, which means that the forces are balanced and cancel each other out. Additionally, the object must not be accelerating, so the net torque acting on it must also be zero.
The object Y must be circumscribed about the polygon X.
The electrical charges were each other neutralized.
