Database Architecture |
| Shared Database |
| C2 is built on a shared database that holds all library information. The high performance level ensures fast access to all information. Records are available immediately after entry. Catalogue records are stored in variable length fields to minimise storage space. C2 also supports multiple bibliographic databases. |
| Full Text Retrieval |
| C2’s searching
capabilities are built on an innovative full-text retrieval system. This
makes retrieval more powerful than most other library systems. It allows
the library to store data in user-defined variable formats, in catalogue
and free-text records, while retaining the power to search them at will.
Full-text retrieval eliminates the need to determine what terms might be indexed in the future. Data is future-proofed and enables users to retrieve information using criteria not specified at data entry. |
| Native File System |
| C2 maintains the database as a collection of files within the native file system of the server hardware platform. User flexibility, security and independence is maximised when existing utilities and facilities can be used with the database files. The server uses sophisticated caching and index compression algorithms to minimise the amount of data transferred to and from user workstations. |
| Ultra-high User Concurrency |
| The C2 server incorporates new indexing technology that allows a very high level of concurrency among clients without jeopardising data integrity. Record-level locking controls interaction between simultaneous data entries. |
