Integration Tasks

Integrating data can become complex if you have not spent adequate time developing an understanding of your data. Give some thought to items and attributes that seem most relevant to the data mining goals and then get started integrating your data.

Task List

• Using Merge or Append nodes in IBM® SPSS® Modeler, integrate the data sets considered useful for modeling.
• Consider saving the resulting output before proceeding to modeling.
• After merging, data can be simplified by aggregating values. Aggregation means that new values are computed by summarizing information from multiple records and/or tables.
• You may also need to generate new records (such as the average deduction from several years of combined tax returns).
