Being cautious and following the few simple rules detailed below will help a lot in ensuring data consistency within the database and in avoiding common errors during database update or data exports.
Most workflows aimed at importing data should contain the following activities: Load file, Reconciliation, Segmentation, Deduplication, Update data.
Using workflow templates makes it very convenient to prepare similar imports and ensure data consistency within the database.
In many projects, imports are built without Deduplication activity because the files used in the project do not have duplicates. Duplicates sometimes appear from importing different files. De-duplication is then difficult. Therefore a deduplication step is a good precaution in all import workflows.
Do not rest on assumption that the incoming data is consistent and correct, or that the IT department or Adobe Campaign supervisor will take care of it. During the project, keep the data cleansing in mind. Deduplicate, reconcile, and maintain consistency when you import data.
An example of a generic workflow template designed for importing data is available in the Example: Workflow template to import data section.
The most efficient format for imports is flat files. Flat files can be imported in bulk mode at the database level.
Example of file to import:
lastname;firstname;birthdate;email;crmID Smith;Hayden;23/05/1989;firstname.lastname@example.org;124365 Mars;Daniel;17/11/1987;email@example.com;123545 Smith;Clara;08/02/1989;firstname.lastname@example.org;124567 Durance;Allison;15/12/1978;email@example.com;120987
Use zipped files for imports and exports when possible. GZIP is supported by default. You can add pre-processing when importing files or post-processing when extracting data, respectively in the Load file and Extract file workflow activities.
Regular imports must be done in delta mode. It means that only modified or new data is sent to Adobe Campaign, instead of the whole table every time.
Full imports should be used for initial load only.
To maintain data consistency in the Adobe Campaign database, follow the principles below:
