You can use machine learning data catalogs (MLDCs) to interpret and optimize the use of disparate data sources, reconcile policies across data use, and democratize data to the edge of business. But to access these benefits, you'll first have to select from a diverse set of vendors — vendors that vary by size, functionality, geography, and vertical market focus. Enterprise architecture (EA) professionals should use Forrester's Now Tech report to understand the value they can expect from an MLDC provider and select vendors based on functionality and role affinity.
