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 and Creating Database Definitions and Values

Once a spreadsheet has been paired with its appropriate ssdef heading definition, the next step is to read the spreadsheet and to create database definitions. The ssdef heading definitions ensure that the column headings can be distinguished from ordinary line items on the spreadsheet. In addition, the ssdef definitions ensure that the correct column names will be appropriate and ready for each value that needs to be processed.

In this step, the spreadsheet is read and each value on the spreadsheet has its context identified. The output from this step is a simple database that lists all the data found on the spreadsheet.
