名词解释题英译中：Inland container depot

You are a database developer for a container manufacturing company. The containers produced by your company are a number of different sizes and shapes. The tables that store the container information are shown in the Size, Container, and Shape Tables exhibit:

Size

SizeID

SizeName

Height

Container

ContainerID

ShapeID

SizeID

Shape

ShapeID

ShapeName

Measurements

A sample of the data stored in the tables is shown below:

Size Table

SizeID SizeName Height

1 Small 40

2 Medium 60

3 Large 80

4 Jumbo 100

Shape Table

ShapeID ShapeName Measurement

1 Triangle 10

2 Triangle 20

3 Triangle 30

4 Square 20

5 Square 30

6 Square 40

7 Circle 15

8 Circle 25

9 Circle 35

Periodically, the dimensions of the containers change. Frequently, the database users require the volume of a container. The volume of a container is calculated based on information in the shape and size tables.

You need to hide the details of the calculation so that the volume can be easily accessed in a SELECT query with the rest of the container information. What should you do?

A. Create a user-defined function that requires ContainerID as an argument and returns the volume of the container.

B. Create a stored procedure that requires ContainerID as an argument and returns the volume of the container.

C. Add a column named volume to the container table. Create a trigger that calculates and stores volume in this column when a new container is inserted into the table.

D. Add a computed column to the container table that calculates the volume of the container.

What purpose does a bridge fitting serve when lashing containers ________．

A.Ties a container stack to the deck

C.Restrains racking loads

D.Restrains the container against horizontal motion

A.void previous(Container parent)
