An object diagram for a library management system. Object Diagrams | Library Management System To illustrate how a library management system operates, we will use an object diagram to show the right and left distribution of objects. The steady state of the system is shown in this diagram as a line going from left to right. To enter, an object must pass between the two distribution points. Objects enter on the right and return on the left. The arrows represent movement through these distribution points which can be directional or non-directional depending on whether they're controlled by software or human behavior respectively. In this example, each arrow represents one instance of movement from one side to another with no interruption between them e.g. 'Alice enters the library'. A library management system is a type of organizational information system, in the sense that it manages the objects (data) of an organization. It is also a type of computer application, in that it uses software to perform many of its functions, but it can also be considered an information technology application given the overall complexity and the non-trivial processing required. OIMs are used to manage data, create reports and maintain records about people, products, customers and services. They provide management systems for managing people's behavior through monitoring what they do (monitoring), controlling what they do (controlling) and simply recording what they do (journaling). The most obvious use of an OIM is to create an audit trail for some transaction. Information systems are typically the domain of Information Technology (IT), however some organizations have IT departments that are separate from their OIM departments. OIMs may be used by any large organization that needs to manage data on a regular basis. Organizational information systems are intended to be shared between multiple departments, so there is usually no single department responsible for the management of an OIM. The typical workflow of using an organizational information system is as follows: 1. A request for information is made by a user, either directly or through some other process, such as a report or form; 2. The information is retrieved from a database, and optionally sent to the user; 3. The information is processed and displayed, and made available for action; 4. The information may be acted upon and modified if necessary; and 5. A report has been generated and made available to users for analysis or reporting purposes. A library management system manages library data, which consists of documents (text, images, audio files), digital media (videos) and metadata (links to other resources). It can also manage holdings (collection size) and circulation (how many books are loaned/borrowed at any given time). The system also manages the physical location of documents with respect to patrons (can a patron access a document). Library management systems commonly support various services, such as:The systems can be set up in such a way that their data can be shared by other systems. These include OPACs, ILSs, MARC databases, Genres/MARC indexing, Genres/MARC full-text retrieval, online public access catalogues and integrated library systems. Systems which allow patrons to place holds or request items are usually called online public access catalogues (OPACs). Holdings are often maintained by the library management system in order to give an indication of how many copies of each item are available. cfa1e77820
