(221) You can access via set records normally through
- A.
  
  A. an entry point record and an owner record.
- B.
  
  B. key data items in the record.
- C.
  
  C. a database pointer.
- D.
  
  D. a database key.
Correct Answer
A. A. an entry point record and an owner record.

Explanation
To access set records normally, you need both an entry point record and an owner record. The entry point record serves as a starting point for accessing the set, while the owner record identifies the record that owns the set. By using both records, you can navigate through the set and retrieve the desired data items efficiently. Using key data items in the record, a database pointer, or a database key alone would not be sufficient for accessing set records normally.

(222) What types of records are defined when a hierarchical relationship is established by sets?
- A.
  
  A. Via Set.
- B.
  
  B. Relationship.
- C.
  
  C. CALC and Direct.
- D.
  
  D. Owner and member.
Correct Answer
D. D. Owner and member.

Explanation
When a hierarchical relationship is established by sets, two types of records are defined: owner and member. The owner record represents the higher-level entity in the hierarchy, while the member record represents the lower-level entity that is associated with the owner. This type of relationship allows for the organization and management of data in a hierarchical structure, where each member is linked to its respective owner.

  A. Via Set.
- B.
  
  B. Relationship.
- C.
  
  C. CALC and Direct.
- D.
  
  D. Owner and member.
Correct Answer
D. D. Owner and member.

Explanation
When a hierarchical relationship is established by sets, the types of records that are defined are "Owner" and "Member". The "Owner" record represents the parent or superior entity in the hierarchy, while the "Member" record represents the child or subordinate entity. This relationship allows for the organization and categorization of data in a hierarchical structure, with each member being associated with a specific owner.

(222) Which type of linkage would be present when the owner record points to the first member record, the first member record points to the next member, and the last member points back to the owner?
- A.
  
  A. Prior.
- B.
  
  B. Relationship.
- C.
  
  C. One-way circular.
- D.
  
  D. Two-way circular.
Correct Answer
C. C. One-way circular.

Explanation
In a one-way circular linkage, the owner record points to the first member record, the first member record points to the next member, and the last member points back to the owner. This creates a circular chain where each member is linked to the next one, but the owner record does not have a direct link to the last member. This type of linkage allows for easy traversal of the chain starting from the owner record and going through each member in a sequential manner.

(222) What clause in the set section determines the logical placement of a new member record added to a set?
- A.
  
  A. Code.
- B.
  
  B. Mode.
- C.
  
  C. Order.
- D.
  
  D. Set selection.
Correct Answer
C. C. Order.

Explanation
The clause in the set section that determines the logical placement of a new member record added to a set is the "Order" clause. This clause specifies the sequence in which the member records are organized within the set. By defining the order, the system knows where to place the new record in relation to the existing records in the set.

(223) Which element of the database structure is not shown by the Integrated Maintenance Data System (IMDS) Data Management System (DMS) schematic?
- A.
  
  A. Set.
- B.
  
  B. Area.
- C.
  
  C. Page.
- D.
  
  D. Record.
Correct Answer
C. C. Page.

Explanation
The IMDS Data Management System (DMS) schematic does not show the element "Page" of the database structure. The schematic likely displays the other elements such as Sets, Areas, and Records, which are commonly used in database organization. However, the absence of "Page" suggests that the IMDS DMS does not utilize a page-based storage system for data management.

- B.
  
  B. from a circled number to a record.
- C.
  
  C. to a boxed number from a record.
- D.
  
  D. from a boxed number to a record.
Correct Answer
B. B. from a circled number to a record.

Explanation
In an Integrated Maintenance Data System (IMDS) Data Management System (DMS) schematic, an off-page connector from another area is identified by an arrow pointing from a circled number to a record. This indicates that the circled number represents a reference to another page or location, and the arrow is pointing towards the record that contains the detailed information. This helps in navigating the schematic and finding the relevant information easily.

- C.
  
  C. the first digit of the area code.
- D.
  
  D. the Transaction Interface Package (TIP) number.
Correct Answer
A. A. a whole number.

Explanation
The correct answer is a. a whole number. In the context of an Integrated Maintenance Data System (IMDS) schematic, the area consisting of one schematic page is denoted by a whole number. This means that the area code used to represent the schematic page is a complete number without any fractions or decimals. This helps in easily identifying and referencing specific schematic pages within the IMDS system.

Correct Answer
A. A. key.

Explanation
A column or combination of columns in a relational table that uniquely identifies a row is called a key. A key is used to ensure that each row in a table is unique and can be used to establish relationships between tables. It is an essential component in maintaining data integrity and facilitating efficient data retrieval and manipulation operations in a database system.

(225) In a relational database,
- A.
  
  A. two tables can have exactly the same name within the same database.
- B.
  
  B. the column selected as the primary key field may not be null.
- C.
  
  C. each row can have more than one value for each column.
- D.
  
  D. a row can be duplicated in a table.
Correct Answer
B. B. the column selected as the primary key field may not be null.

Explanation
In a relational database, the primary key is a column or a combination of columns that uniquely identifies each row in a table. It is used to ensure data integrity and enforce uniqueness. The primary key field cannot be null because it must have a value in order to uniquely identify each row. If the primary key field allows null values, it would defeat the purpose of having a primary key. Therefore, option b is the correct answer.

(225) What type of key establishes the relationship with records in one table to records in another table?
- A.
  
  A. Table Key.
- B.
  
  B. Foreign Key.
- C.
  
  C. Primary Key.
- D.
  
  D. Relational Key.
Correct Answer
B. B. Foreign Key.

Explanation
A foreign key is a type of key that establishes the relationship between records in one table to records in another table. It is used to link two tables together by referencing the primary key of one table as a foreign key in another table. This allows for the establishment of relationships and maintains data integrity within a database system.
