What is the Peer-layer?
The entities comprising the layers on different machines are called peers.The peer may be processes,hardware devices or even human beings. In other words, it is the peers that communicate by using the protocol.
What is meant by saying that organizational subsystems are interrelated and interdependent?
If you break down the words interrelated and interdependent you find that they are: inter-related: related to each other inter-dependent: dependent on each other This is only true within the system/organization where the subsystems are located. So basically you are saying that subsystems are related and depend on one another in order to function most efficiently.
How functional dependency is related to database table design?
The functional dependency is related to the database table design through the foreign and primary keys. The foreign and primary keys are functionally dependent on each other.
What is difference between primary key and foreign key?
A primary key is an attribute (or combination of attributes) that uniquely identifies each row in a relation. A primary key is designated by underlining the attribute name. The primary key of an entity set allows us to distinguish among the various entities of the set. A foreign key is an attribute in a relation of database that serves as the primary key of another relation in the same database.
Is it necessarily that a foreign key is primary key in other table?
It is not mandatory that is must be a primary key but it must be a unique key in the other table.
When the PK of one entity does not contain the PK of a related entity the relationship is?
When the primary key (PK) of one entity does not contain the primary key of a related entity, the relationship is typically a "one-to-many" or "many-to-many" relationship. In this scenario, the primary key of the first entity can exist independently of the second entity, indicating that multiple instances of the related entity can correspond to a single instance of the first entity. This structure allows for more flexible data modeling where entities can be associated without strict dependency on each other's primary keys.
Is Hitachi related to Sony?
Other than both Hitachi and Sony being Japanese companies, no. They are separate entities.
Is rent expense an other expense?
If rent is paid for any activity which is directly related with the primary business activity then rent is not other expense, but if rent is paid for activity which is not directly related to primary business activity then it is other expense.
How do you represent key constraints in ER diagram?
In an Entity-Relationship (ER) diagram, key constraints are represented by underlining the attribute(s) that form the primary key for an entity. This indicates that the attribute(s) uniquely identify each instance of the entity. Additionally, for foreign keys, a dashed underline can be used to denote attributes that reference primary keys from other entities, highlighting their role in establishing relationships.
What was the primary focus of the us foreign policy in the decade after world war 1?

Should foreign aid be given directly to governments or should it be directed to other entities within the country?
The record of foreign aid over the past 60 years or so is that it is usually misappropriated and misspent by corrupt governments, and it winds up doing little if any good for the country to which it is given, so yes, it would seem that governments are not the best recipients of such aid, and perhaps there are other entities which could make better use of the money.
Could a table only have one primary key and only one foreign key?
Yes it could. It would have a primary key for its own use and it could then have a foreign linking it to another table. If it is only linked to one other table, then it would only need one foreign key. It is also possible to have the same foreign key linking to more than one table.
Defining table creates links between tables?
A defining table establishes relationships between different tables in a database by using foreign keys, which reference primary keys in other tables. This allows for the organization of data into related entities, enabling efficient data retrieval and management. By creating these links, a defining table helps maintain data integrity and supports complex queries across multiple tables. Overall, it is essential for normalizing data and minimizing redundancy.
Define a family as a primary group?
A family as a primary group is like a set of people who are related to each other living together as one.
