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.

The Intermediate Database

The output from the previous step results in the creation of what is termed the “intermediate database”. For all practical purposes, the intermediate database is a working database that is not meant to hold the final output of corporate data. In a way, the intermediate database holds “raw” data.

The data held in the intermediate database serves as input for two different functions. One of those is the creation of the mnemonic database, which holds strictly metadata. The second is the actual corporate data. The mnemonic database holds the metadata that was pulled from the spreadsheets, while the corporate database holds the actual values of data from the spreadsheets.
