This section will evolve as the project progresses and will be updated regularly to reflect changes.

Data Model

Data Dictionary

This section would hold information on the tables that will be part of the SCSB middleware database. Information includes, a brief description of the table, the columns involved, a brief description of the columns, data type, the default value (if applicable) and whether the column is mandatory/unique.

SCSB uses Hibernate ORM to persist data.

The following is the list of tables used in SCSB

accession_t

The accession_t table holds the pending records that are inbound to SCSB during ongoing accession. The ongoing accession process might happen at different times of the day in GFA LAS but are processed as a bulk job (usually nightly) in SCSB to optimize performance. The data is used to fetch records from partner's ILS and the data ends up in bibliographic_t, holdings_t, item_t and other related tables. Records are marked 'pending' if they are waiting to be processed or 'completed' post processing. Those that are marked 'completed' are purged regularly through the PurgeAccessionRequests job.

Entity Class: AccessionEntity.java

Use Cases effecting changes in table: Ongoing Accession

Table Type (Master/Transactional): Transactional

Column Name	Description	Data Type	Default Value	Mandatory	Unique	Comments
ACCESSION_ID	Primary key	INT(11)	System-generated	Y	Y	This is an incremental system-generated value which would help to uniquely identify the accession record within the table in SCSB database
ACCESSION_REQUEST	The request content in JSON format is stored as a BLOB.	LONGBLOB	NULL
CREATED_DATE	The time-stamp at which the accession was received in SCSB.	DATETIME	NULL
ACCESSION_STATUS	The status of the record in the accession process.	VARCHAR(45)	NULL			'Pending' and 'Completed' are the two valid statuses.

bibliographic_holdings_t

The bibliographic_holdings_t table holds both the owning institution bibliographic record id and their respective holdings id. This helps in many-to-many linking between holdings and bibliographic records in case of multiple copies at different locations.

Use Cases effecting changes in table: Initial Accession, Ongoing Accession, Submit Collection

bibliographic_holdings_t vs bibliographic_item_t

Though bibliographic_holdings_t and bibliographic_item_t may look similar in form and function they differ in that the former maintains relationship between the bibliographic data and the holdings data while the latter maintains the relationship between bibliographic data and item data. A single bibliographic data might have multiple items in case of serials and multiple holdings in case of multiple copies in different locations. Multiple bibliographic data might be attached to a single item in case of bound-withs.

bibliographic_t

The bibliographic_t table holds information on bibliographic records. This is a crucial table in SCSB to maintain information about the collections. The table is populated by either the Initial Accession or Ongoing Accession processes. The information from this table is used to display collection details under Search and Collection tabs in SCSB UI. The data in this table can be modified through the Submit Collection API. The bib related XML is stored as a BLOB in the table in the MARCXML format.

The collection_group_t table holds information on the Collection Group Designations (CGD) prevalent among the item records and their description. The values that are currently in use are Open, Shared, Private and Not Available. All partners' items are classified into one of these three CGDs. A partner's 'Private' item is available for request only by patrons of the partner institution, whereas, a partner's 'Open' and 'Shared' items are available for request by patrons of all partner institutions. The 'Not Available' CGD is used in case of dummy records. The CGD is referenced in the item_t tables and is useful in ascertaining validity of the requests.

It holds information such as their description, the owning institution they belong to and the Delivery Restrictions, if any. It also has PWD Delivery Restrictions, ReCAP Delivery Restrictions and Circulation Desk Location. Delivery Restrictions defines the locations where a particular item with a customer code can be delivered as part of retrieval. Similarly, PWD Delivery Restrictions and ReCAP Delivery Restrictions defines locations where a particular item with a customer code can be delivered as part of deaccession (PWD - Permanent Withdrawal Direct) and retrieval request for ReCAP staff, respectively.
