Data Model
The Data Model has three parts: Tables, Views, and Stored Procedures. API limitations and requirements are documented in this section; you can use the SupportEnhancedSQL feature, set by default, to circumvent most of these limitations.
Tables
The CData Cmdlets PowerShell Module for Mailchimp models the Mailchimp API in Tables so that it can be easily queried and updated.
The cmdlet dynamically retrieves custom fields for the ListMembers tables when you connect; any changes you make to these custom fields, such as adding a new field or changing a custom field's data type, are reflected when you reconnect.
Dynamic tables
Along with the default static tables, the cmdlet also allows querying on dynamic tables. These are tables that are created based on the "audiences" (also called "lists") in your Mailchimp account.
For example, suppose you have these 3 audiences in your account: Old Audience, New Audience, VIP Audience. For each of these audiences the cmdlet creates 2 new tables: One starting with "ListMembers_" and the other with "ListMergeFields_". So, for the case in hand, these 6 tables will be created:
- ListMembers_OldAudience
- ListMembers_NewAudience
- ListMembers_VIPAudience
- ListMergeFields_OldAudience
- ListMergeFields_NewAudience
- ListMergeFields_VIPAudience
The above 6 tables are created by removing spaces from the audience's name and appending the result to "ListMembers" or "ListMergeFields" with an underscore.
Tables starting with "ListMembers_" display all members for a specific audience along with custom fields' values.
The ones starting with "ListMergeFields_" display all custom fields' names for members in that audience.
Views
Views are tables that cannot be modified. Typically, data that are read-only and cannot be updated are shown as views.
Dynamic views
Along with the default static views, the cmdlet also allows querying on dynamic views. These are views that are created based on the "audiences" (also called "lists") in your Mailchimp account.
For example, suppose you have these 3 audiences in your account: Old Audience, New Audience, VIP Audience. The cmdlet lists 3 views based on them: ListMemberTags_OldAudience, ListMemberTags_NewAudience, ListMemberTags_VIPAudience.
The above 3 views are created by removing spaces from the audience's name and appending the result to "ListMemberTags" with an underscore. They return the tags that are assigned to each member of the audience you've specified.
Stored Procedures
Stored Procedures are function-like interfaces to the data source. They can be used to search, update, and modify information in the data source.
