Outline• What is Data Mining and Data
Warehousing and Why Do We Do It?• Our Library and University• Patron Statistical Categories• Application Server• Reporting
3
Collecting Transactional Data
• ILSs collect transactional data for circulation and allocation of collection funds.
• ILL and Document Delivery services supply general transactional data.
• Reports from vendor services– Bibliographic utilities– Subscription agents– Book jobbers
4
• Most ILSs have search and web server logs
• Most (if not all) Databases have usage reports
• Link Resolver logs• Proxy Server logs• Many other ways of collecting
transactional data.– Gate counts– Reference transaction counts– Reshelving counts
Collecting Transactional Data cont.
5
What would we like to see?
• Breakdowns by department and majors.
• Combined usage by department/majors of more than one library service.
6
What is Data Mining and Data Warehousing
• Extracting data from legacy systems and other resources;
• cleaning, scrubbing and preparing data for decision support;
• maintaining data in appropriate data stores; • accessing and analysing data using a variety
of end user tools; • and mining data for significant relationships.
• Chaffey, D., Mayer, R., Johnston, K., & Ellis-Chadwick, F. (2002). Internet Marketing: Strategy, Implementation and Practice (2nd ed.). Financial Times/ Prentice Hall.
7
• The primary purpose of these efforts is to provide easy access to specifically prepared data that can be used with decision support applications such as management reports, queries, decision support systems, executive information systems and data mining.

Which categories of patrons are
accessing which services?
17
First Step – Patron Statistical Categories
18
• Voyager Patron Database allows a maximum of 10 statistical categories per patron record.
• Decide which statistical categories are
needed for each patron group defined.
• Work with your University Information Systems Department to extract the relevant data from the relevant sources.
19
Groups and Services
• Major• Status
– Undergrad or Grad– Faculty, Adjunct Faculty
or Staff

• Circulation– Books– Media– Reserve– By Fund Code– Location
• ILL / Document Delivery• Databases• Library Web Pages

22
Challenges with combining data from various services
• Little to no linkage of data
• Multiple user IDs for authentication
23
Second Step – Setup an Application Server
24
What is an Application Server?
• A machine or its software that works in conjunction with a web server to deliver application services such as the dynamic creation of a webpage from content stored in a database. From http://www.webtools.ca.gov/help/Glossary.asp• Web Server Software (Apache or IIS)
• Database Management System – DBMS (MySQL, Oracle, MS SQL Server)
• Scripting Language (Perl, PHP, ColdFusion, ASP)
25
Why an Application Server?
• Relevant data in logfiles need to be in a database to be analyze.
• Need your own DBMS to create new tables and queries.
26
• Decide how you will use the Application Server.
• Decide on the best and most plausible configuration.
27
Authentication of ILL and other forms are routed through the EZProxy server

Patron Privacy and Standards
43
Using Voyager as the model for Patron Privacy
44
• Active Circ transactions are stored in a table with patron ID and statistical categories.
• Completed Circ transactions are stored in a table without the patron ID, but still with the patron statistical categories.
• The Patron Table contains the total counts of transactions for each patron, but no link to which transactions they are.
45
• EZProxy transactions would be stored in one table with patron statistical categories, but without the user ID.
• User ID s would be stored in another table with counts for each service divided by academic year.
• Logs are collected monthly and loaded and deleted monthly.
46

Reporting and Standards
• Reporting– Emailed periodically - e.g., daily
dossiers, and other event triggered reports.
– On demand, via email, web pages or a printer.
