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.

Organizing Data Inside the ssdef Table

The ssdef table can be arranged in one of two basic manners. The first arrangement is by individual column names. In this arrangement, only one column name at a time is stored. In order to determine what the header line looks like, the line must be reconstructed, a column name at a time. This is often referred to as the “individual column” method.

The second way the ssdef table can be structured is by the capture of the entire line, where all of the column names are captured at once. This is referred to as the “composite column” method.
