In UML, object diagrams provide a snapshot of the instances in a system and the relationships between the instances. By instantiating the model elements in a class diagram, you can explore the behavior of a system at a point in time.
Sequence diagrams, commonly used by developers, model the interactions between objects in a single use case. They illustrate how the different parts of a system interact with each other to carry out a function, and the order in which the interactions occur when a particular use case is executed.

UML diagrams generally permit the annotation of comments in all UML diagram types. The comment object is a rectangle with a folded-over corner as shown below. The comment can be linked to the related object with a dashed line.
Instead of cluttering your sequence diagram with several objects and groups of messages that will confuse the reader, draw a few smaller sequence diagrams that aptly explain what your system does. Make sure that the diagram fits on a single page and leaves space for explanatory notes too.
A collaboration diagram, also known as a communication diagram, is an illustration of the relationships and interactions among software objects in the Unified Modeling Language (UML). These diagrams can be used to portray the dynamic behavior of a particular use case and define the role of each object.
However, collaboration diagrams are best suited to the portrayal of simple interactions among relatively small numbers of objects. As the number of objects and messages grows, a collaboration diagram can become difficult to read and use efficiently. Additionally, collaboration diagrams typically exclude descriptive information, such as timing.
In UML, the two types of interaction diagrams are collaboration and sequence diagrams. While both types use similar information, they display them in separate ways. Collaboration diagrams are used to visualize the structural organization of objects and their interactions. Sequence diagrams, on the other hand, focus on the order of messages that flow between objects. However, in most scenarios, a single figure is not sufficient in describing the behavior of a system and both figures are required.
Library management is a sub-discipline of institutional management that focuses on specific issues faced by libraries and library management professionals. Library management encompasses normal managerial tasks, as well as intellectual freedom and fundraising responsibilities. Issues faced in library management frequently overlap with those faced in managing non-profit organizations.[1]
The basic functions of library management include overseeing all library operations, managing the library budget, planning and negotiating the acquisition of materials, Interlibrary Loan [ILL] requests, stacks maintenance, over seeing fee collection, event planning, fundraising, and human resources.[2]
Most of the libraries that store physical media like books, periodicals, film, and other objects adhere to some derivative of the Dewey Decimal System as their method for tagging, storing, and retrieving materials based on unique identifiers.[3] The use of such systems have caused librarians to develop and leverage common constructs that act as tools for both library professionals and library users alike. These constructs include master catalogs, domain catalogs, indexes, unique identifiers, unique identifier tokens, and artifacts .
An important aspect of library management is planning and maintaining library facilities. Successful planning is defined as "active planning that ensures an organization will have the right people in the right place at the right time for right job" [4] Planning the construction of new libraries or remodeling those that exist is integral since user needs are often changing. To supplement their operating budget, managers often secure funding through donor gifts and fundraising. Many facilities have begun including cafes, Friends of the Library spaces, and even exhibits[5] to help generate additional revenue.[6] These areas should be taken into account when planning for building expansions.
The Journal of Library Administration began in 1980 and is currently published by Routledge eight times per year. It is a peer-reviewed academic journal that discusses issues pertaining to library management.[10]
Interaction Diagram are used in UML to establish communication between objects. It does not manipulate the data associated with the particular communication path. Interaction diagrams mostly focus on message passing and how these messages make up one functionality of a system. Interaction diagrams are designed to display how the objects will realize the particular requirements of a system. The critical component in an interaction diagram is lifeline and messages.
Interaction diagrams help you to visualize the interactive behavior of a system. Interaction diagrams are used to represent how one or more objects in the system connect and communicate with each other. 2ff7e9595c
