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.
What else can I help you with?
What conditions must be met for an object to be at equilibrium?
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.
Objects A and B are brought close to each other. Object A will soon become positively charged. Identify the charge that must transfer for this situation to occur.?
Electrons must transfer from object A to object B for object A to become positively charged. When electrons are transferred from one object to another, the object losing electrons becomes positively charged, while the object gaining electrons becomes negatively charged.
How many degrees must an object be revolved through to be viewed orthographically?
An object must be revolved 90 degrees to be viewed orthographically. Orthographic views are typically shown from the front, back, top, bottom, left, and right sides of an object, each requiring a 90-degree rotation.
What kind or friction must be overcome to start movement of a stationary object?
Static friction must be overcome to start movement of a stationary object. This is the friction that exists between two surfaces that are not moving relative to each other. Once the static friction is overcome, the object can start moving.
In raising an object, must there be an increase in which type of energy that the object possesses?
Yes, in raising an object, there must be an increase in potential energy that the object possesses.
Which two items must be unique to each computer and cannot be duplicated on a network?
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.
What are the properties of relations in database management?
1.each row must have unique(pk)in a relation. 2.database must have a unique name. 3.each column must have unique name.
What type of administrative membership allows you to add attributes and object classes to the Active Directory database?
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. ^^^^^
If object A is inscribed in object B then what can be said about each?
Object B must be circumscribed about object A.
If object A is circumscribed about object B then what can be said about each?
.Object B must be inscribed in object A.
What does each user and group object has which must be unique across an entire active directory domain?
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.
Why must create user in oracle todo your work in oracle?
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.
What is a restriction for table to be a relation?
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.
What conditions must be met for an object to be at equilibrium?
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.
If a polygon X is inscribed in an object Y then what can be said about each?
The object Y must be circumscribed about the polygon X.
What must a neutral object contain?
The electrical charges were each other neutralized.
What must you calculate to determine the acceleration of an object?
You must calculate the change in velocity during each unit of time.
