Importance of Database

What is a database?

It is a tool used to store and keep track of information relative to activities that an individual or a company/organisation has with the university

Are databases part of our lives?

YES

1. In choosing a restaurant from the Yellow Pages, we indirectly use a database

2. A hotel room is obtained by searching from a database (single room, non smoking, with TV)

3. Some of us may have a Christmas Card database (who do we send the card to, address, did we also send it last year?)

The Advantages Of a Database

1. Pooled information

Functions such as departments, units, as well as single individuals (academics, administrative staff) usually accumulate a wide range of information on individuals and companies

If these “islands” are united, everybody will have a much more complete picture.

2. Duplication of efforts

In your university there are probably dozens of address lists of the same companies and individuals.

Time and money is wasted in keeping them all up-dated.

Non synchronised lists lead to annoyed companies and individuals who are contacted from several different directions.

Through the database, different parts of the university would access and update the same info.

3. Presenting a unified “face”

Emphasising the earlier point, if different sections of the university keep maintaining separate databases, the relationship building process will be undermined by the irritation of the alumni/companies.

This problem can be reduced if all elements of the university coordinate marketing, development and other externally-facing operations through a centrally shared database.

4. Rationalised IT investment

Different systems managed by different units/functions can only deplete university resources faster.

The database is a focused investment developed to encourage cooperation

5. Developing an institutional memory

A database is also a vehicle to capture people’s knowledge.

Every time some member of staff leaves, unless his/her data is recorded, such information is lost.

Achieving a shared database

There is more to a database than just records.

The success of a database revolves around issues related to human resources, politics (!), and practical constrains.

Where do you look for information for your database?

How do you start putting one together?

Who are you going to ask to start working with you on it (and sharing)?

Who is going to pay for the software?

Common Problems of Students

Concentration

Concentration is essential for study. Many students may find it hard to concentrate on their study properly. They just read the lines of their lessons but they are not able to grasp the ideas in the words because they can’t properly concentrate on it while study. It is a common problem.

To improve the power of concentration student should have enough sleep daily, take regular exercise, study in a place with less distraction, avoid multi-tasking, take short breaks in long study, and get your all work done before you sit to study.

Exam Stress

It’s very common that student becomes too much stress at the days of exam. He thinks about how to make full preparation in time. He fears he may not complete his preparation for the coming paper. He fears that he may fail and this worry doesn’t let him study.

Entity, Attributes and Relationship

What is Entity in Database?

A person, place, object or event in the user environment about which the organization wishes to stores information about. Some specific examples of entities are Employee, Student, Lecturer. An entity is analogous to a table in the relational model. E.g. Teacher is the entity, about which is to make a records.

What is Attributes in Database?

A property or characteristic of an entity or relationship type that of the interest of the organization is called Entity. E.g Teacher is entity and their name,, age, contact number etc is the attributes. The above diagram clearly shows it

Relationship and Relation

A relationship is an association (link) of entities where the association includes one entity from each participating entity type. 

While a relation is a named two dimensional tables of data. Each relation consists of a set of named columns and a number of rows.

Relational Database

A database that represents data as a collection of tables in which the relationship are represented by common fields in the related tables.

Entity type

A collection of entities that shares common properties

Types of Entities

• Strong entity type

An entity type that exists independently of other entity types

The strong entity type is called the identifying owner

• Weak entity type

An entity type whose existence depends on another entity type.

Cardinality Constraints 

The number of instances of one entity that can or must be associated with each instance of another entity.

Database Management System (DBMS)

Database Approach

A database is a shared collection of records.

Back end:

Collection of tables/ relations that stores database.

Front End:

Forms which is to be filled by the user is the front end.

Advantages of Database Approach: 

• Program data Independence.
• Planned data Redundancy.
• Improved data Consistency.
• improved data Sharing.
• Increase Programmer Productivity

Database

A database is a collection of information that is organized so that it can easily be accessed, managed, and updated. In one view, databases can be classified according to types of content: bibliographic, full-text, numeric, and images.

How database Come into Existence

Some years back people use many files and registers to store data. In Government and Private offices people use registers to store the records. It takes time to store these data. As well as it takes many place to store old government records and after that these records become useless. There were also many problems before database system as follow:

• Loss of data and problem of destruction.
• Need more space to store these data
• Difficult to find records
• Problems of managing these files
• Difficult to transfer these files
• Difficulty in making backups

Characteristics of a Successful Student

1. Successful students attend classes regularly. They are on time. They listen and train themselves to pay attention. If they miss a class, they feel obligated to let the teacher know why before class begins, if possible, and their excuses are legitimate and reasonable. They make sure they get all missed assignments (by contacting the teacher or another student), and understand specifically what was covered in class. Successful students take responsibility for themselves and their actions.

2.  Successful students take advantage of extra credit opportunities when offered. They demonstrate that they care about their grades and are willing to work to improve them. They often do the optional (and frequently challenging) assignments that many students avoid.

Why do people find mathematics difficult?

Some general themes from the answers below...

1. Mathematics is not difficult: Mathematics is no more difficult than other fields. Cooking is difficult. Ballet is difficult. However #2...
2. Your lack of ability "hits you in the face": People find mathematics difficult because it is easier to realise that it is difficult. With other difficult tasks it is easier to fool one's self into believing that one is good at said task, but this doesn't work with mathematics. If you're bad at mathematics it will show you just how bad you are.
   
   
   

What Causes Students to Fail Courses in College?

Lack of Preparedness

The first year of college is often a major transition. Students leave home for the first time, balance work, school and other activities, and must make the majority of their life decisions independently. In some cases, students aren't mentally, emotionally or academically ready to succeed in college classes. Some lack the necessary motivation and work ethic. Others struggle with the emotional difficulties that come with being on their own. Colleges often offer personal counselors who work specifically with students trying to balance academics with personal life challenges.

Poor Attendance

One of the surest ways to fail a class is to consistently miss it. Some courses include grading components, such as in-class activities, pop quizzes and team projects that can't be made up. In many instances, the bigger issues is that you are out of the loop in a number of ways. Missing classes can lead to missed homework assignments, papers and projects, especially if you don't check in regularly with the instructor. You also miss critical discussions of topics and content, which can lead to poor performance on tests.

How to Prepare For Exam

Tip 1: Start early
Preparation for exams should begin earlier than the day before the test. You can’t cram an entire unit of information into an all-nighter. Get started at least a week before the exam.

Tip 2: Organize
Begin by making yourself a calendar outlining a daily schedule of topics for review. Cover a small amount of material for each class each day. Every time you complete a topic, give yourself a mini review.

Tip 3: Outline
Once you have decided what you need to study and how much time you need to spend studying, it is time to actually study. One of the best ways is to make succinct outlines. As you read over your textbook and class notes, write a brief summary for each topic. Highlight the areas in your outline that were most troublesome. When you have finished with all the material, you will have an outline you can review.

Student Life

“Student Life” refers to the life of students who receives systematic education in an educational organization (schools, colleges, universities, etc).

 Student life is neither full of joy nor full of sorrow. It is a mixture of both. It is a blessing that parents come forward to bear all the expenses incurred by a student. This indicates that they place much hope on him and that he must make himself worthy of their hope.

In other words, he will have to build up his life in such a way that he can fulfill his own dreams and meet the expectations of those who love him.

Student

A student is a learner, or who attends an educational institution.In most nations, the English term is reserved for those who attend university, while a schoolchild under the age of eighteen is called a pupil.

A student is someone who studies. Not someone who is taught or someone who
drinks latte and plays computer games: but rather, someone who studies. We must
bear in mind the active component of studying that is required by this model of what
it means to be a student. After a secondary education in the UK, it would be
reasonable to suppose that being a ‘student’ means ‘being taught’: but the passivity
inherent in this model is entirely inappropriate. A student is not someone who
receives teaching and merely vomits it back; rather a student is someone who is
responsible for her own learning and study. An ‘active learner’ is a person who takes charge of their own studies
