What should you do about your proliferation of data marts now that your organization is building a data lake? The short answer: Get rid of the data marts … or at least most of them!

You have three main options for how to deal with your proliferation of independent data marts as part of your data lake initiative:

 Retire some or all of the data marts, and replace them with data lake functionality.

 Isolate some of the data marts, and leave them in place alongside your new data lake.

 Incorporate some of your data marts as components of your data lake.
