Colleagues describe them as "When I came to work at AtBusiness Lauri was responsible of database standards -- how the SQL should be used. Much of my SQL skills beyond what is teached at university comes from what I learned from him, not so much as directly from him but by doing in practice what he wrote. I recall that some of his insights about modeling hierarchical data in relational database where proposed to scientific publications as article. I don't know if that article was published or not, but those insights I have found useful regardless. I can recommend Lauri as high level expert of SQL. His theorethical knowledge how to apply SQL is really note worthy. He is also very able to form his knowledge in format useful for studing. That combination makes him very suitable for teching how SQL should be used or as expertice manager of DB team."
