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.

A Missing Value

Now consider a different variation of the same spreadsheet - a spreadsheet with one of the values missing. Figure 3.6 shows the same spreadsheet but with the value in row 2/line 3 omitted.

The result is that row 2/line 3 reads “eold linefeed row id(2) xlstab value xlstab xlstab value”. The interpretation of that line is that there is a value for column 1 and for column 3, but not for column 2.
