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.

Functions Served by the Data Elements

The data found in the intermediate database serves a variety of functions. Lineage is preserved by including the spreadsheet name and date processed. If necessary, any value that has been processed can be traced back to a specific spreadsheet and a specific date.

The context of the value that has been lifted includes the row identifier and column name. The row identifier and the column name combine together to specifically describe a value in “real world” terms.

And, of course, there is the value itself, as lifted from the spreadsheet.

These elements combine to start the basis for corporate data. Figure 7.1 illustrates the different types of data elements found in the intermediate database.
