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 internal view of the first row identifier looks the same as it does in the example shown in Figure 3.4. But the second row in the multiline spreadsheet will be different: “eold linefeed xlstab value xlstab value xlstab value”.

In order to manipulate a spreadsheet, the analyst must operate confidently at the internal level. The analyst must understand the meaning of the special characters and their structure in order to be able to correctly interpret the spreadsheet.

The importance of the ability to understand spreadsheets internally cannot be understated. It is only at the internal level that a connection can be made between a value and its relevant context...
