The system begins by analyzing every column of every table at its disposal. First, it produces a statistical summary of the data in each column. For numerical data, that might include a distribution of the frequency with which different values occur; the range of values; and the “cardinality” of the values, or the number of different values the column contains. For textual data, a summary would include a list of the most frequently occurring words in the column and the number of different words. Data Civilizer also keeps a master index of every word occurring in every table and the tables that contain it.
Then the system compares all of the column summaries against each other, identifying pairs of columns that appear to have commonalities — similar data ranges, similar sets of words, and the like. It assigns every pair of columns a similarity score and, on that basis, produces a map, rather like a network diagram, that traces out the connections between individual columns and between the tables that contain them.

Our democracy is based on majority rule tempered by minority rights. I had always assumed that the major threat to our democracy, if one arrived, would come through a “tyranny of the majority” that cast aside or subverted the constitutional protections of the minority. What we have seen between 2010 and 2016, however, is not the emergence of a tyranny of the majority, but an increasingly irreversible capture of our elected institutions by a focused and uninhibited minority.
What is so discouraging to me, therefore, is not that I fear a blatant demise of American democracy and the rise of a traditionally recognizable dictatorship. Rather, I am bewildered as to how to proceed in a situation in which the legitimizing mechanics of democratic majority rule are preserved even as the reality of an increasingly irreversible minority control prevails.
I am bewildered how to conduct political discourse and persuasion — about how to conduct politics, in short — when each political tribe lives in its own reality, increasingly incomprehensible to the other, and with no agreed-upon standards and measures concerning how we might ascertain facts and truth, much less agreement on even the desirability and relevance of such an effort.
Sadly, our democracy is challenged not just by the fraying of a democratic political culture through ever-intensifying polarization and demise of traditional norms. It is also challenged by a basic collapse of two vital institutions: rule through electoral majorities and a free media. That is the predicament we face today.
