I've spent more than 35 years in the data and analytics industry. Either hands-on, as an ETL developer building ETL pipelines, designing databases, data modelling, building and managing data warehouses, lakes and everything in between, through to leading global data organizations. I've seen the rise and fall of every trend, from relational databases to MPP systems, Hadoop clusters to cloud data warehouses, and more recently lakehouses and the explosion of data options now available. I've seen new acronyms rise like weeds and vendors rebrand the same ideas with shinier buzzwords.
