Hello, 1C

To add 
Gender
as a new attribute, click the 
Data
tab, then click 
Add
(Ins) for the 
People
catalog. 
In 
Properties
, enter 
Name
, and 
Synonym
once again will be generated 
automatically. There is one more thing to do. You need to specify the way 
to store data in the 
Gender
attribute. As you can see in 
Properties
, the 
default type for an attribute is 
String
.
Figure 4-18. Adding the Gender attribute 
You can leave everything as it is, but in that case, every time when adding 
a new person to the catalog, the user will have to enter gender manually in 
the 
Gender 
attribute. First, typing information manually for a large number 
of records is a very time consuming job. Second, there is a high risk of 
human error such as typo, wrong information input, and inconsistent values 
as there are many variations of writing genders. These errors, regardless of 
their nature, will make complicated any future automatic analysis of this 
data. 
The first thing that may come to mind is to create the another catalog 
where specify both genders, and then use those catalog items. It is a 
reasonable idea, but creating a new catalog for just two objects is a 
redundant task. Which way is better then? There is another, new for 
you configuration object.
Enumeration
is an object that is created and filled with data at the 
development of an applied solution stage. An enumeration can store a 
limited, known beforehand, and same type of data. 
Gender
is precisely the 
type of data that is good to be stored as an enumeration, rather than as a 
catalog. 
To create a new enumeration, leave
