The Personalization service stores information about visitors by using a person profile. The profile is structured to collect data about persons (information specifically about the visitor), events (captured visitor actions from a website or other location), and touches (a group of associated events that occur no more than 30 minutes apart from one another).

Although some of the fields in the person profile are required by Personalization for its operation (for example, geographic and device-related information stored in the touch), you can use certain fields to store additional data that you may want to use for personalization—for example, information about gender for your visitors. The Personalization service includes a certain number of custom fields for each type of this information:

• Person table: 50 custom fields
• Touch table: 20 custom fields
• Event table: 50 custom fields

The method by which Personalization does this is to create an alias (also known as a column name) for your custom data to an existing data structure element, which you are reassigning to collect and store the data that you require. For example, custom field 10 in the Person table might have the alias of gender. Personalization displays gender as the field name in the person profile and in the segment builder.
