Data management

Data Management is the first step towards the implementation of the graph objective as defined by the Graph Workflow model.

Data management entails raw data preparation, data validation, metadata record keeping, data combinations, scale conversion and anything that has to do with generating and preparing the data for graphing.

Exploratory data analysis describes a special class of statistical methods that provide critical input for data management.

The iterative nature of the Graph Workflow model necessitates revisiting data management at every step, and questioning the appropriateness of data form and data scope. That is to say, preliminary decoding may identify the need to transform variables, convert scales, combine variable into ratios, differences, indices, manage outliers, create data bins and aggregates, and so on. This iterative process continues until the visual becomes fully informative and bears all qualities of graphical representation.
