The fullfiment subject area contains several tables related to the readers who borrowed the document including the "patron details" and "borrower details" tables. According to the documentation the data stored in the patron detail table are the characteristics of the reader at the time of the transaction. The "borrower details" table stores the characteristics of the reader at the time of the request.
It would be useful if the patron statistical codes were stored in the "patron details" table so that they can be historized.
Indeed, like many other libraries, we use these statistics to identify the academic department of the reader, his or her level of study and other information that allows us to make a detailed analysis of the use of our collections. However, this information evolves throughout the schooling or career of our readers. In addition, administrative re-enrolments take place throughout the academic year and the basic reports are therefore difficult to produce.
The addition of statistical codes to the patron details table would allow us to follow the usage of our collections according to the statistical codes of our readers.
