Object modeling represents the static structure of objects and their relationships using object diagrams. An object diagram shows instances of classes, their attributes and values, and relationships between objects through links representing associations, generalizations, or aggregations. Object diagrams are useful for understanding object behavior and relationships in a system, as well as its static view and for forward and reverse engineering.

Unified Modeling Language (UML) is a general purpose modelling language. The main aim of UML is to define a standard way to visualize the way a system has been designed. It is quite similar to blueprints used in other fields of engineering.
UML is not a programming language, it is rather a visual language. We use UML diagrams to portray the behavior and structure of a system. UML helps software engineers, businessmen and system architects with modelling, design and analysis. The Object Management Group (OMG) adopted Unified Modelling Language as a standard in 1997. Its been managed by OMG ever since. International Organization for Standardization (ISO) published UML as an approved standard in 2005. UML has been revised over the years and is reviewed periodically.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

COLLEGE BUS MANAGEMENT SYSTEM PROJECT REPORT.pdfKamal Acharya
The College Bus Management system is completely developed by Visual Basic .NET Version. The application is connect with most secured database language MS SQL Server. The application is develop by using best combination of front-end and back-end languages. The application is totally design like flat user interface. This flat user interface is more attractive user interface in 2017. The application is gives more important to the system functionality. The application is to manage the student’s details, driver’s details, bus details, bus route details, bus fees details and more. The application has only one unit for admin. The admin can manage the entire application. The admin can login into the application by using username and password of the admin. The application is develop for big and small colleges. It is more user friendly for non-computer person. Even they can easily learn how to manage the application within hours. The application is more secure by the admin. The system will give an effective output for the VB.Net and SQL Server given as input to the system. The compiled java program given as input to the system, after scanning the program will generate different reports. The application generates the report for users. The admin can view and download the report of the data. The application deliver the excel format reports. Because, excel formatted reports is very easy to understand the income and expense of the college bus. This application is mainly develop for windows operating system users. In 2017, 73% of people enterprises are using windows operating system. So the application will easily install for all the windows operating system users. The application-developed size is very low. The application consumes very low space in disk. Therefore, the user can allocate very minimum local disk space for this application.

2. ObjectModeling
Object Modeling gives static structure of objects and their relationship
to one another.These are useful for demonstration of system to customers.
Object Modeling is represented by using object diagram.
3. ObjectDiagram
It is used to model instances of things contained in class diagram.
It is a diagram that shows sets of objects and their relationship.
It also represents static structure of system.
4. Purpose Of Object Diagram
It shows object relationships in a system.
Understand object behavior and their relationships.
Shows static view of a system.
Forward and reverse engineering.
5. Terms And Concepts Of Object Diagram
1. Object :
It is instance of a class and each object is represented by a
rectangle which contains name of object and its class name underlined and
separated by a colon.
6. 2. ObjectWith Attributes :
As with classes we can list object attributes in separate
compartment. Each object attributes must have values assigned to them.
7. 3. Active Objects :
Objects that have their own processes that control their
activities are called as active objects.They are represented by a symbol of object
with thick border lines.
4. MultipleObjects :
It is represented by a symbol as object if attributes of objects
are not important
8. 5. Links :
These are the relationship between objects. Links are
instances of association. It is represented by solid line.
Relationship between objects can also be generalization or aggregation.
Generalization Symbol Aggregation Symbol
Objects that fulfill more than 1 role can be self linked.
9. Object Instances :
Object Instance is also called as class object that it is
nothing but instance of a class.Objects are rendered as instance usually on
object diagrams.
Example :
Following diagram shows instance of a class order and of
class customer.
The Order class has number of instances o1,o2,o3. It can
also be represented by multiple objects if attributes are not important.
