Abstract: Since the introduction of the relational model of data, the join operation is part of almost all query languages and data processing engines. Nowadays, it is not only a formal operation but rather a dominating pattern of thought for the concept of data connectivity. In this paper, we critically analyze properties of this operation, its role and uses by demonstrating some of its fundamental drawbacks in the context of data processing. We also analyze an alternative approach which is based on the concept of link by showing how it can solve these problems. Based on this analysis, we argue that link-based mechanisms should be preferred to joins as a main operation in data model and data processing systems.
