In this undertaking I have to roll up some entity, so an entity attributes and at last ERD.I think I will larn more about entity, attributes, Entity Relationship Diagram to make this undertaking.
Description:
Entity
An Entity is an object or existent thing such as a tabular array or signifier. An Entity contains some information about himself. In the entity some informations can be stored.
Properties
Properties means the information or inside informations of an Entity. Attribute may incorporate assorted sorts of value like numeral, Characters, Integer etc. Simply attributes are the belongingss of entity.
Entity Relationship Diagram ( ERD )
An entity-relationship diagram is a information mold diagram and technique. ERD can make a graphical representation of the relationships between entities, the entities, and within an information system.
There are three type relationships in the Entity Relationship Diagram ( ERD )
One to One
One to Many
Many to Many

Entity Relationship Diagram ( ERD ) :
Relationship sum-up:
In my ERD plot some relation description are given in the below:
In the Entity Relationship Diagram I find out the relation between section and capable country is one to many, because one section may hold many capable countries.
In the scenario I can see one capable country may hold more plans.
In the ERD diagram the relationship between plan and faculty is one to many. Many faculties are under of a plan. Module is used a foreign key of plans.
In the ERD diagram the relationship between pupils and faculties are one to many, because one pupil may hold more than one faculty. In the relationship pupil primary key is used as a foreign key in the faculty entity.
In the ERD diagram the relationship between pupil and test is one to many. One pupil may take part more tests.
In the ERD diagram the relationship between pupil and coursework is one to many. One pupil may take part in the more coursework.
In the ERD diagram the relationship between enrollment and pupil is one to many. The enrollment may be registers for more pupils at same clip.
In the ERD diagram really I see the one to many dealingss. For this ground I include one to many relationships in the ERD diagram. In the existent life for database one to many relationship is perfect to me.
Drumhead
In this undertaking I draw an entity relationship diagram. To pull the diagram I find out some entities and properties of entities. To make this undertaking I besides learn about entities, properties and entity relationship diagram.
Task-02
Introduction:
It is said to normalise in the undertaking 2. For doing a database successfully Normalization must be needed. The activities of a database depend on standardization. Standardization helps to do a database rebelliously. In the undertaking I will seek to normalise for a section system in the organisation. The standardization occurs in some stairss. In the undermentioned stairss are given.
Description:
Standardization
In the organisation all activities now depend on the computing machine system. Some corporate organisation need database system for commanding all information. As a consequence database is most popular and indispensable things in the universe. For doing a database successfully standardization is the traditional manner. Without standardization it is impossible to do a database. Standardization is the procedure is used to form the informations absolutely in a database. I normalize the section information for some specific intent. The intent of standardization is divided into two parts. Removing unneeded informations and guaranting informations dependences. If same informations stay in some tabular array together the database may victim. Often it may data in the unrelated tabular array. To work out these jobs we can be done standardization. The intents of standardization are worthy to diminish the sum of infinite a database consumes and guarantee that information is logically stored. The public presentation of database direction system depends on the standardization.
Some stairss are indispensable for standardization. The stairss are given briefly in the followers:
Gathering informations
Gathering informations is the first measure of standardization. When I normalize I will roll up all information in the phase. I will implement all informations of this measure in the following measure.
Choosing a key
For making standardization a key is indispensable. The key is the chief informations for standardization. All informations depend on the key. The key must be one from garnering informations.
First Normal Form ( 1NF )
Some functions have to follow in the stairss. Repeating informations in the standardization, sometime it may harmful for standardization, so it necessary to take reiterating informations in the standardization. Removing reiterating informations is the chief work in this undertaking.
Second Normal Form ( 2NF )
Second normal signifier ( 2NF ) is used to different and take same informations in the database. The phase besides provides farther information for taking same informations in the database. The chief activities of the phase:
The all informations of first normal signifier must be represented in the phase.
Same information in the rows of database tabular array are removed in the phase.
The relationship of new tabular array is made in the phase.
Third Normal Form ( 3NF )
In the 3rd normal signifier some activities are occurred. The undermentioned activities are given in the below:
All demands of the 2nd normal signifier are present in the phase.
The activities of the phase is removed some columns that are non dependent upon the primary key. The taking informations and information are non depended on the primary key of tabular array. For this ground these columns informations and information are removed.
Optimization
Optimization is the last measure of standardization. I will bring forth the whole standardization by bring forthing a standardization diagram. The standardization diagram is symbol of a better database. If standardization tabular array is clear, informations base become clear.

Summary:
In the undertaking I normalized for a section. I normalize for keeping database direction system. To make this undertaking I analyzed about standardization. I think I normalized good. Clear standardization helps to do a better database direction system. I learned more about standardization to make this undertaking.
Undertaking 3
Introduction:
The undertaking 3 contains some subjects. Database Management System ( DBMS ) is component of the undertaking. I will make a database by utilizing Database Management System ( DBMS ) . There are some ways to do database. But I will make database in the SQL waiter, because it is easy and flexible to me. To do database I will do some tabular array, each tabular array will incorporate minimal 5 records.
Description:
Some stairss I followed to make this undertaking. The stairss and demands are given in the below:
Database Management System ( DBMS ) :
To pull off a database some strong functions are followed. Database direction system is a sort of environment where all sorts ' functions and ordinance are included. A database direction system ( DBMS ) works as a database director. Database Management System ( DBMS ) is computing machine plan or package. The package helps others computing machine users create and entree informations in a database. Anyone can entree the information, where information is located it is non fact, It manages user petitions so that users and other plans are free from holding to understand informations in a multi-user system, on storage media and, who else may besides be accessing the information. Database direction system checks the unity of the database. The DBMS besides manage the hallmark procedure, merely authorized user and authorised web can entree the database. DBMS helps to do a secure database. Database direction system 's environment helps to do a good relationship in the database.
The activities for this undertaking are following:
