📄️ Operators (acces)
The acces database (often located at /bases/acces/acces) defines the User Profiles and permissions within the system. It interacts closely with the users database to determine what an operator can do after logging in.
📄️ Acquisitions (Acq)
The Acquisitions module relies on three main databases to manage the workflow from suggestion to purchase.
📄️ Configuration Files (par/def)
Two key files control how ABCD locates and interacts with its databases.
📄️ Copies (Inventory)
The Copies database acts as the central inventory for the library. It contains one record per physical item (book, journal issue, CD, etc.).
📄️ Overview
This section provides technical documentation for the internal CDS/ISIS databases used by ABCD. Understanding these structures is essential for advanced administration, reporting, and troubleshooting.
📄️ Loan Objects
The Loan Objects database is an intermediate database used by the Circulation module to group copies under a single bibliographic title to apply loan policies efficiently.
📄️ System Log
The Log Database acts as the internal audit trail for ABCD. It records system-wide events such as user logins, database updates, and operational errors.
📄️ Physical Architecture
ABCD uses the CISIS technology (compatible with CDS/ISIS). A "Database" in ABCD is not a single file, but a collection of related files with the same name but different extensions.
📄️ Reservations
This database manages the queue of reservations for items that are currently on loan or otherwise unavailable.
📄️ Suspensions & Fines
The suspml database records sanctions applied to users, such as monetary fines or suspension of loan privileges.
📄️ Transactions (Loans)
The Transactions database (trans) records all active loan operations. When an item is returned, the record is usually moved to a history database (e.g., logtrans) or marked as returned, depending on configuration.
📄️ Users Database
The Users Database (typically named users) is the central repository for operator authentication in ABCD. It stores the credentials required to log in to the Central module (Cataloging, Circulation, Acquisitions) and the Site Administration.
📄️ Patrons (Users)
The Users database (often located in /bases/users/ or shared with /bases/acces/) stores information about library patrons (borrowers).
