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.

Finding Errors

One value of the intermediate database is that if errors are found in a spreadsheet, and if the errors need to be corrected, it is relatively simple to destroy the intermediate database and recreate it.

The intermediate database gives the organization a “second chance” at creating valid corporate data.

In addition, the intermediate database gives the analyst a “sand box” to play in, where data can be easily created and recreated without having to commit to a final format.

A third value of the intermediate database is that it creates a place where several spreadsheets can be processed together and where the merger of the spreadsheets can be considered without having to make a commitment to the final corporate database.

In short, the intermediate database gives the organization a lot of flexibility in its movement from spreadsheet data to corporate data.
