Alma is the library services platform that is replacing Sierra and Ebsco Holdings Management. This platform will encompass the catalog, electronic resource management, acquisitions, circulation and Ohiolink borrowing/lending ("fulfillment"), and patron management.
Each category of inventory has a similar, but slightly different, record structure. 3 Categories of Inventory:
Print (i.e. everything physical: books, DVDs, microfilm, kits, etc.)
Electronic (ebooks, ejournals, databases, streaming media, etc.)
Digital (files owned by your library, e.g. institutional repository files, digitized archival records)
The inventory model for physical resources in Alma is structured with three levels: The bibliographic level, the holdings level, and the item level. Physical inventory, such as a book or a serial, will have a metadata record at each of these levels: The bibliographic record, the holdings record, and the item record. In fact, a bibliographic record could have more than one holdings record, and each holdings record could have more than one item record. The holding record provides the link between the bibliographic record and the physical inventory (items), as can be seen in the following diagram.

Digital Inventory follows the same general record structure as shown below:
