•Data is everywhere — in many forms

•We seek to bring order to data

•Creating tables is one way to do this

•All metadata is data — but data is not necessarily metadata

Practical I•Open Excel

•Enter data related to 3 favorite books in these columns:

•Title

•Author Last Name

•Author First Name

•Save as Excel file

•Save as CSV file too!

•What’s a CSV?

•How is a CSV different from an XLS file?

Recap II•Data modeling allows for a formal

structuring of information

•Information should be organized by notion of discrete objects and distinctive attributes

•In tables, objects become rows of information, and attributes become the columns

•Unique identifiers are useful attributes that help identify and relate data objects to one another

Practical II (a)•Imagine a data model for art &

architecture:

•Country … e.g. France, Spain, USA, Germany, etc.

•Person … e.g. Picasso, van der Rohe, etc.

•Residency … Periods of time artist spent in a country

Residency

end date Date

Practical II (b)

•Add a 4th column to your Excel (containing an ID) table and save it as a new CSV file:

•books_ids.csv

•Make sure your IDs are unique from everyone else’s -- how can we ensure this?

Consistency is [usually] key!

“color” vs. “colour”

“Rembrandt” vs.“Rembrandt

Harmenszoon van Rijn”

“coarse” vs. “rough”

in. vs. cm.

“steamship” vs. “steamboat”

Why does it matter?

Does “steamboat” = “steamship” ?How do “stupid” computers know that?

steamship

How to improve conformance in

data:

•Develop style guides

•Use a controlled vocabulary

•Consult an authority
