In case you have no background in computer science, entity relationship is a method that conceptually identifies the interacting, and independent objects( both physical and otherwise) in an information system with the view to avoid data redundancy, maintain data integrity, improve data efficiency, increase resource utilization in terms of storage management and access speed or system response time. Pls let stop here. An instance of your diagram, which I will stress you little, is to quickly image
1. A hostel and rooms in it, here Hostel as well as the rooms are treated as different entities.
2. imagine manager and employee under him in an organization, even though they can all be referred to as employees yet manager is different entity
In a nut shell we use a line to link two interacting entities and the cardinality( which is to be discuss professionally as either one to one, one to many). That is all.
I am not too good at drawing but I could conceptualize it mentally.
If this does not satisfy you do not hesitate to mail me at: maduchudi@Yahoo.com I will always be for you all.
What else can I help you with?
What is amp-hr of three 3 volts dc battery connected in parallel?
According to me the information about the 3 Volts DC batteries is incomplete i.e.The amp-hr capacity is not provided.If this is known then the answer would be 3X the amp-hr .

What is the Btu output of an electric heater rated at 15 Kw?
A bit north of 50,000btu/hr
What is the speed of light in kilometres?
Speed of light c = 299792458 m/s × 1 km/1000 m = 299792.458 km/s. Speed of light c = 299792.458 km/s × 3600 s/ 1 hr = 1079252848.8 km/hr.
Role of HR in TPM?
HR, which stands for Human resources, is responsible for finding the best and most efficient employees for a particular task. This then creates the best scenario for TPM, which stands for Total Productive Maintenance. Together, accurate assumptions can be made on the quality and time management of the task.
What graph shows the relationship of a stars absolute magnitude and its temperature?
Its called an HR diagram or a Hertzsprung-Russell diagram.
What relationship is shown on the HR diagram?
The Hertzsprung-Russel diagram shows brightness versus color (the color reflects the star's temperature).
What does the HR diagram depict?
The HR diagram, also known as the Hertzsprung-Russell diagram, depicts the relationship between the luminosity and temperature of stars. It shows how stars are distributed in terms of their brightness and temperature, allowing astronomers to classify stars based on these characteristics.
Why is the hr diagram important to scientist?
The main reason that the HR Diagram is so useful and important to scientists is, you can tell the size of the star by plotting it on the HR Diagram. The different sizes of stars form a pattern on the HR diagram.
What are the colors of the HR Diagram?
The colors of the HR Diagram are:BlueBlue-WhiteYellowOrangeRed-OrangeRed
Why is there no neurton stars in the hr diagram?
Of course they are on the HR diagram. They are simply not on the main sequence.
Where are stars on the hr diagram?
The HR diagram contains only stars - so everywhere.
What type of relationship is shown on a HR diagram?
It is a chart showing a scatter chart of stars according to their temperature and their luminosity (or absolute magnitude).
What two star characteristics does the hertzsprung - Russell diagram compare?
The HR Diagram compares the relationship between the stars' absolute magnitudes or luminosities versus their spectral types or classifications and effective temperatures.
What two star characteristics does Hertzsprung Russell diagram compare?
The HR Diagram compares the relationship between the stars' absolute magnitudes or luminosities versus their spectral types or classifications and effective temperatures.
What is the location on the HR diagram where most stars lie known as?
The location on the Hertzsprung-Russell (HR) diagram where most stars lie is known as the main sequence. The HR diagram is a plot of stellar luminosity against surface temperature. The main sequence is a prominent band that extends diagonally across the HR diagram from high temperature and high luminosity to low temperature and low luminosity. The majority of stars, approximately 90% of all stars, are situated along the main sequence on the HR diagram. These stars are often referred to as main-sequence stars. They exhibit a smooth relationship between surface temperature and luminosity, with varying sizes and masses but sharing this common characteristic of lying on the diagonal band from the upper left to the lower right of the HR diagram.

Does An HR diagram plots a stars luminosity and surface temperature?
Yes, an HR diagram plots a star's luminosity (brightness) against its surface temperature, also known as color or spectral type. This graph shows the relationship between these two characteristics for different stars, allowing astronomers to classify and study them.
