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.

“Correctness” of Data

There really are two aspects to the “correctness” of data. One aspect is the accuracy of the data value. For example, if the number “7” should be the number “9,” that data value would be considered inaccurate.

The other aspect to the correctness of data is the structural correctness of data. This is an issue when in one spreadsheet, the vehicle identification number is the one the manufacturer designates. In another spreadsheet, the vehicle identification number is the shipping number used in transport of the vehicle. The problem is not necessarily that these two numbers are different, but that these two numbers have a different significance.
