On this episode, we speak with not 1, but 3 guests, all solutions architects with MongoDB. Solutions architects help our customers use MongoDB in the best way and our topics today run through the Principles of Data Modelling, our newly announced Relational Migrator Tool, and Client Side Field Level Encryption (CSFLE). Our first guest is James Milles. James talks to us about the Principles of data modelling, the considerations to take into account in defining your data model and he outlines how a data model can evolve over time and the reasons for why and how your data model may change and evolve. After James, we have Anand Sanghani. Anand talks to us about the newly announced MongoDB Relational Migrator (which Mark Porter, MongoDB’s CTO, also talked about in Episode 145) and how it makes it easier for people to work with data, particularly legacy relation technologies and also the challenges they face moving off a relational stack. Finally we have, Pierre Petersson who joins me to talk about Encryption, in particular, MongoDB’s Client Side Field Level Encryption in multi cloud environments. Pierre discusses how MongoDB’s approach helps manage encryption keys in a cloud agnostic way & we briefly dive into queryable encryption which was also announced at MongoDB .Local London.
