Which of these can join offline business systems data with online data collected by Google Analytics?
Data Import lets you join the data generated by your offline business systems with the online data collected by Analytics. This can help you organize, analyze and act upon this unified data view in ways that are better aligned with your specific and unique business needs. For example, as a web publisher, you could join hits collected by Analytics with data dimensions exported from your CMS and CRM systems to analyze the relative contributions of authors to your site.

Data Import lets you upload data from external sources and combine it with data you collect via Analytics. You can then use Analytics to organize and analyze all of your data in ways that better reflect your business.
If you use a variety of systems and tools to run your business, you can use Analytics to join and analyze that data in one place. For example, you can turn separate CRM data, ecommerce data, and Analytics data into a single comprehensive view of your business.
Each business system you use generates its own data store. Your CRM might contain information like customer-loyalty rating, lifetime value and product preferences. If you are a web publisher, your content management tool probably stores data dimensions such as author and article category. If you are an ecommerce business, you might create catalogs that describe your products according to prices, style, size, etc. And (since you’re reading this), you most likely use Analytics to track traffic and performance for your websites, mobile apps or appliances. Typically, this data exists in its own “information silo,” unaffected and uninformed by the data in other silos.
