Turning Spreadsheets into Corporate Data

By: Bill Inmon

Overview of this book

Spreadsheets are a popular way to store and communicate business data, but, although they are easy to create and update, they are not reliable enough to be used for making important corporate decisions. With this book, you can gain insight into how to maintain spreadsheets, how to format them, and then convert them into a database of reliable and useful information. Turning Spreadsheets into Corporate Data starts with a quick history of spreadsheet usage. You’ll learn the basics of formatting spreadsheets, including how to handle special characters and column headings, and how to convert the spreadsheet first into an intermediate database and then into corporate data. You will also learn how to utilize the mnemonic dictionary that is created along with the intermediate database. The later chapters discuss the immutability of data and the importance of organizational and political considerations during the data transformation. By the end of this book, you’ll have the skills and knowledge needed to convert your spreadsheets into reliable corporate data.

Limited Editing

For the most part, data that comes from the spreadsheet environment remains just as it was found. As it enters the corporate world, though, some small amount of editing is acceptable. These types of editing include:

  • Tolerance edits, where a numeric value is between 1 and 10, for example.
  • Simple numeric edits, as in changing the European number 2.350 to the American form of 2,350.
  • Standard acronym edits, like changing Texas to TX and New Mexico to NM.

Note that with these simple edits, the meaning of the data is not changed.
