--- title: "Basic Historical Group" --- # Basic Historical Group > A basic historical transaction group is any transaction group that logs data to a database. ### To create a Historical Group 1. In the Project Browser, right-click on the **Transaction Groups**, and select **New Historical Group**. 2. Select tags from the OPC Browser and drag them into the **Basic OPC/Group Items** area of the transaction group. The target databases are represented in the **Target Name** column and when the group executes, the data will be stored in the columns of these names. 3. Go to the **Action** tab and select **Timer** to specify how often the group executes. There are other options that help configure the data as it enters the database. For example, having an additional column for the time stamp.
