Object Oriented Data Model (OODM): An Object Oriented Data Model is used in logical database design and accessing of database. It includes three different types of relationships namely, aggregation, generalization and particularization and four types of operations namely, database creation, object expansion, retrieving of objects and schema Class: A class is a collection of data members and member functions, which are used to represent the overall structure of the project. The objects are created to access the data members and member functions of the class. The process of creating a new class from the existing class is called as inheritance. Here, the existing class is named as super class and the newly created class is named as sub class. Object: The variable for this defined class is called the object. It is also called as instance of a class. It is a unit of code which is derived from the processes. It is an instance of the class which has its own procedures for the execution.

Class:

A class is a collection of data members and member functions, which are used to represent the overall structure of the project.

The objects are created to access the data members and member functions of the class.

The process of creating a new class from the existing class is called as inheritance. Here, the existing class is named as super class and the newly created class is named as sub class.

Object:

The variable for this defined class is called the object.

It is also called as instance of a class.

It is a unit of code which is derived from the processes.

It is an instance of the class which has its own procedures for the execution.

Dijkstra's Algorithm (part 1). Consider the network shown below, and Dijkstra’s link-state algorithm. Here, we are interested in computing the least cost path from node E (note: the start node here is E) to all other nodes using Dijkstra's algorithm. Using the algorithm statement used in the textbook and its visual representation, complete the "Step 0" row in the table below showing the link state algorithm’s execution by matching the table entries (i), (ii), (iii), and (iv) with their values. Write down your final [correct] answer, as you‘ll need it for the next question.
