If we create a simple design of student exam database in the perspective of object oriented database management system model then what kind of attributes and classes in the database can follow in the diagram object oriented management system model?- Part 2

How to create a simple design of student exam database in according to the object oriented database management system model?-Part 2

The Subject of the students

If we create a simple design of student exam database in the perspective of object oriented database management system model then what kind of attributes and classes in the database can follow in the diagram object oriented management system model?- Part 2

It is class according to the object database and there fields are their subjects in the class of ‘subjects of student’. There are some basic subject has taken in the class are English, Hindi, Mathematics, Science and S.S.T. in the fields or attribute. It holds numerical data type in their fields.

{English = Numerical data type}

{Hindi = Numerical data type}

{Mathematics = Numerical data type}

{Science = Numerical data type}

{S.S.T. = Numerical data type}

The Parent’s signature

This image database record to stores only image data type. The parent signature must be included in the student exam database to verify the student exam database of particular student. It holds image data type in the field or attribute.

{Parent Signature = GIF Data type}

The signature of Guardian

It is an optional attribution in the database if the parents of student are not present in their signature. It holds the image data type in the field or attribute.

{Signature of Guardian = GIF Data type}

The signature of Principal

It is a strong attribute in the database because the Principal must be verifying the student exam databases. It holds the image data type in the field attribute.

{Signature of Principal = GIF Data type}

Describe the different ways of mobile communication systems for users?

Describe the different ways of mobile communication systems for users? Mobile communication makes it easy to connect with many users through the different types of ways to provide the communication system, share the information to each other and make communication between two or more users through the mobile devices. Such as:- an internet service provides many ways to connect the users in the text, audio, image and video file or data connections sharing the information to each other using these data types to communicate to each other. The user needs to communicate with the other user on the data communication system application software provide the process the data to send the file or message to the user who is connected to the communication application software through their user ID name or email to communicate to share the text or audio file or video file or image file also can be shared into the application software to the user such as:- if the application software provide the chatt...

I am exploring the points on if data centers uses a SAN how it is bigger than SANs?

Is data centers using a SAN and how much are data centers bigger than SANs? The data centers are used to provide the big data analytics for the website and companies to provide the processed data for making different types of informed decisions at a large amount of data processing in the data centers because it is a very big area to install into the building and many buildings if it requires to install into many buildings. The large requirement of data centers installation is necessary because the data centers uses many types of computers, storage devices, network attached storages, network devices such as:- servers, switches, hubs, routers, bridges, repeaters, gateways etc. data cables and different types of network equipment to use in the data centers to make a large area of data processing for the companies uses and major projects for website at larger industrial area for website for data processing. The storage area network is used to provide the high performance of data processing...
