Shared interests defines the bond of community of the creative individuals and small businesses that comprise the Creative Enterprise Cluster. Once overlooked and dismissed as marginal contributors to local and regional economic vitality, creative researchers such as Richard Florida and Stuart Rosenfeld are shining a bright and constructive light on the self-employed and very small businesses that make up the Creative Enterprise Cluster.

The advantage of clustering is twofold. Firstly, by storing the field or fields comprising the Cluster Key once instead of multiple times, storage is saved. More significantly, the fields of the Cluster Key are often indexed, so the high maintenance indexes for those fields are also reduced from containing multiple key entries to a single key entry. The arguably more significant advantage to Clustering is to expidite join queries. When 2 (or more) tables repeatedly have their rows accessed together via a join query, those tables are good candidates for Clustering.
