The data (and information) quality domain is supported by several decades of high quality research contributions and commercial innovations. Research and practiceindataandinformationqualityischaracterizedbymethodologicalaswell astopicaldiversities.Thecross-disciplinarynatureofdataqualityproblemsaswell as a strong focus on solutions based on the fitness for use principle has further diversified the related body of knowledge. Although research pluralism is highly warranted, there is evidence that substantial developments in the past have been isolationist.Asdataqualityincreasesinimportanceandcomplexity,thereisaneed tomotivateexploitationofsynergiesacrossdiverseresearchcommunities. Theabovefactorswarrantamultiprongedapproachtothestudyofdataquality management spanning: organizational aspects, i.e. strategies to establish people, processes, policies, and standards required to manage data quality objectives; architectural aspects, i.e. the technology landscape required to deploy developed processes, standards, and policies; and computational aspects which relate to effectiveandefficienttoolsandtechniquesfordataquality. Despite a significant body of knowledge on data quality, the community is lacking a resource that provides a consolidated coverage of data quality over the threedifferentaspects.Thisgapmotivatedmetoassembleapointofreferencethat reflectsthefullscopeofdataqualityresearchandpractice. In the first chapter of this handbook, I provide a detailed analysis of the data quality body of knowledge and present the rationale and approach for this handbook,particularlyhighlightingtheneedforcross-fertilizationwithinandacross research and practitioner communities. This handbook is then accordingly struc- tured into three parts representing contributions on organizational, architectural, ix
