SFX Database 3
Sources • Where a user is coming from, beginning a search • Examples: • A&I database • OPAC • Online journal • Sources must be Open. URL-enabled! • Librarians work with Sources available in their own library environments; can decide what Services would be most desired by users 4
Targets and Target Services • Where a user “lands” • Services are the “facilities”: • A ‘get. Author’ service would run a search on an author’s name • A ‘get. Full. Txt’ service would link to the full text of a particular article from a Target publisher • A ‘get. Holding’ service would link to a record in a library catalog • Targets must have a link-to syntax that supports the Service 5

Database Tables SOURCE TARGET SOURCE SERVICE TARGET SERVICE OBJECT PORTFOLIO 7
Objects • The OBJECT table stores objects and information about objects • • • Title ISSN/E-ISSN CODEN Abbreviated titles (alternate) Object type Related objects (title or ISSN change) • Three types of objects are defined in the SFX database: • Journals • Books • Preprints 8
Object Portfolios • The OBJECT PORTFOLIO tables stores information to connect TARGET SERVICES and OBJECTs • For example, this table indicates which journals are available from the Cambridge University Press collection, or from JSTOR Arts & Sciences 1 collection 9

Object Lookup [set at Target Service] YES • • • Is used when objects need to be attached to a particular target service The Target Service will show up on the SFX Menu screen only if the information you start from is part of the Object Portfolio of that Target Service Is mainly used for get. Full. Txt Target Services NO • • • Is used when no objects need to be attached to a particular target service The Target Service will show up on the SFX Menu screen, regardless of the object with which you start Is used for more general, “searchoriented” Target Services, such as get. Holding or get. Web. Search 11
