As digital channels continue to grow, they drive greater diversity in our data landscape. At Yorkshire Building Society, our purpose is to provide real help with real life and this relies on data from a myriad of sources. This diversity creates a need for points of intersection, where data can unite to feed customer and business insights. How do we create these hubs of intersection and what can modern technology offer? Speaker: Mark Walters Lead Enterprise Data Architect for Data & Information Yorkshire Building Society

5. Restrictions on our external network make it difficult to move
larger amounts data meaning that we have to host “on premise”
rather than “in the cloud”.
Around 60% of our change portfolio are projects where
integration costs outweigh costs of the new package.
Data Integration is our biggest challenge!
