In this session you will learn about a typical challenge in legal information management: how to determine whether two (or more) offers to sell, or purchase, products (or services) represent the basis of a legally binding contract. You will learn which techniques are used to correlate the data in terms of the range of objects, their quantities, their qualitative properties, while also taking into account the temporal properties of the offers. You will also learn how clustered columnstore indexes can be used to improve the efficiency of the queries needed to solve this important legal problem.
