LSPs and APIs

LSPs and APIs

•  A bit of background

•  What do we need from APIs

•  How Innova@ve are approaching this


A liBle bit of history…

•  Integra@on is not new – Bibliographic data sources – EDI integra@on – Student registry

•  Batch processing • Web services

– Self-‐service


Prolifera@on


Why do we need APIs?

•  Flexibility of the applica@on

•  Giving libraries choice and control

•  Engaging with new/different parts of your ins@tu@ons


APIs vs SQL Access

•  Documented

•  Different views

•  Version controlled


What do we need from APIs?

•  Documenta@on

•  Developer community

•  Need to be used by the company as well as the community


Why Sierra Open Architecture


SIERRA ARCHITECTURE

Presenta@on Layer

Data Access Layer

SQL Database

Business Services Layer RESTful APIs SIP2, NCIP

INN-‐Reach Decision Center

SQL Queries Crystal Reports


SIERRA OPEN DATA ACCESS

•  Query through ‘views’ – Simplifies reporting on a normalized database – Allows us to optimize efficiency – Encapsulate schema so it can evolve

•  Data manipulation through APIs – Ensures consistent enforcement of business

logic – Significantly reduces interfacing effort – Allows underlying implementation to evolve


SQL Access


Sierra Direct SQL Access


•  Ease querying for the report •  A ‘façade’ in front of one or more tables •  They are read-‐only •  Insulate you from changes so we don't break your reports

What is a ‘view’?


SELECT p.record_num AS "patron_record", p.expiration_date_gmt AS "expiration_date", count(c.id) AS "checkout_count" FROM sierra_view.patron_view p JOIN sierra_view.checkout c ON c.patron_record_id = p.id WHERE p.expiration_date_gmt < current_date GROUP BY 1,2 ORDER BY 3 desc


Expired patron records with checked out items


Create Reports with SQL

Another sample report could be quickly run to identify all bibliographic records with ten or more holds waiting. Note that the library chose to include the date the first item was cataloged. This library would use the gathered information to plan additional acquisitions because their DVD collec-tion is quite heavily used.

CONCLUSION Sierra provides real-world advantages to today’s libraries. With the Sierra Open Database and Sierra DNA, librarians can have direct access to all of the libraries’ data, more quickly, than in any other solution. Properly informed and applied, decisions made by librarians can shape collec-tions, save significant funds in library operations, and increase patron satisfaction by delivering material in mul-tiple formats for their use.

Sierra brings powerful, sophisticated data access to its libraries. Library staff can take advantage of valuable, real time access to all Sierra’s underlying bibliographic and transactional data through the application of Sierra DNA and Sierra Views. Best yet, Sierra is developed, enhanced, and backed by Innovative so you’ll know that we’ll be there for you when you need us. Open data access, documented design, and trusted support lead to a wealth of possibilities for your library.
