Description: Entity An Entity is an object or existent thing such as a tabular array or signifier. We will write a custom essay sample on Entity Relationship Diagram Analysis or any similar topic only for you Order Now 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 The chief constituents of Entity Relationship Diagram ( ERD ) Entity Properties Relationship Cardinality Entities: Department Capable Area Staff Plan Faculty Student Registration Examination Consequence Coursework Attendance Advancement Entities with Properties: Department Department_ID ( PK ) Department_Name Department_Details Department_Leader Discipline Subject_Area_ID ( PK ) Subject_Area_Leader Subject_Area_Name Subject_Area_Details Department_ID ( FK ) Employee Employee_ID ( PK ) Employee_Leader Employee_Type Employee_Name Employee_JoiningDate Employee_Address Department_ID ( FK ) Plan Program_ID ( PK ) Program_Leader Program_Name Program_Type Program_Details Subject_Area_ID ( FK ) Registration Registration_ID ( PK ) Registration_Date Registration_Type Registration_cost Faculty Module_ID ( PK ) Module_Name Module_Leader Module_Details Module_Type Student_ID ( FK ) Program_ID ( FK ) Student Student_ID ( PK ) Student_Name Student_Type Student_Details Student_Address Module_ID ( FK ) Registration_ID ( FK ) Examination Exam_ID ( PK ) Exam_Details Exam_Name Exam_Date Exam_Time Student_ID ( FK ) Consequence Result_ID ( PK ) Result_Name Result_Type Result_Details Result_Date Result_time Exam_ID ( FK ) Coursework Coursework_ID ( PK ) Coursework_Name Coursework_Type Coursework_Details Student_ID ( FK ) Attendance Attendance_ID ( PK ) Attendance_Name Attendance_Type Attendance_Details Student_ID ( FK ) Advancement Progress_ID ( PK ) Progress_Type Progress_Details 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. Th e 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.

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: MY database: Generated Script from â€Å" Generate SQL Server Scripts Wizard † : SET ANSI_NULLS ON Travel SET QUOTED_IDENTIFIER ON Travel IF NOT EXISTS ( SELECT * FROM sys.objects WHERE object_id = OBJECT_ID ( N ‘ [ dbo ] .

I finished the undertaking really carefully. As a proven I show some screen shooting of quires. I besides show SQL quires in the assignment. Undertaking 5 Introduction: There are five undertakings in the assignment. Each undertaking is made for a specific and different subject. Such a undertaking is task 5. In the undertaking 5 I will seek to stand for a study for whole assignment. The study will incorporate the description of my system design for a section of an organisation. In this study I will besides include the inside informations information about undertaking one to five. Description In the phase I will seek to give a solution for this study. Title Report no- Database Design and Development Recipient- Mrs Jesmin Aktar Author- Shanta Maria Introduction of my premise: The rubric of the assignment is College Database Development. The college needs a computerized system for keeping the activities of a section. To keeping the section activities the college needs an ideal database direction system. To complete these activities of this assignment I mentioned each subject for the assignment in the separately. I think I learned more things as pupil, to make this assignment. After completing each undertaking right I will bring forth a study for discover my accomplishment on my analysis, design and thought accomplishment. Overview of whole assignment: The sum-up of the whole assignment, I want to bring forth a study. The study is given at the below: Undertaking 1 Entity An Entity is a existent thing such as a tabular array or signifier. An Entity contains some information about himself. The information of entity can assist for designation of entity. Properties Attributes refers the inside informations information of an Entity. There are many types are fixed for property. These values are like numeral, Characters, Integer etc. Properties are the chief belongings of entities. Entity Relationship Diagram ( ERD ) An entity-relationship diagram is a diagram for informations patterning. Entity relationship diagram ensures the relationships between entities, the entities, and within an information system. Entity relationship diagram makes a database good understand. There are three type relationships in the Entity Relationship Diagram ( ERD ) One to One One to Many Many to Many The chief constituents of Entity Relationship Diagram ( ERD ) Entity Properties Relationship Cardinality Undertaking 2 Standardization Some corporate organisation need database system for commanding all information. To command information of organisation database must be needed. As a consequence database is most popular and indispensable things in the universe. 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 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. In the assignment I followed some stairss for standardization. The stairss are given in the below: Gathering informations Choosing a key First Normal Form ( 1NF ) Second Normal Form ( 2NF ) Third Normal Form ( 3NF ) Optimization Undertaking 3 I used SQL waiter to do database in this undertaking. Making database was the function of the undertaking. As a consequence I designed a diagram and a database in the undertaking. Undertaking 4 The undertaking holds information for SQL quires. Harmonizing the undertaking some quires are made to use in the database. To make SQL quires in the undertaking I learned more things about SQL bid and other secure information of SQL waiter. Footings of mention: The scope for investigated system is extended. All the inside informations about the system hold given. The current system and the new system image are clear in the scenario. Anyone can see and compare the scenario. The study focuses on the section of an organisation. The study is bring forthing with a inside informations description and information of the complete system analysis and design portion for the section of an organisation. Procedures and methods: In my assignment I used some techniques. I have investigated all the process in many ways. In the assignment I followed the operation and practically system of college and others pull offing activities. The chief process and method of the assignment is to settle the current system jobs and besides to present an ideal database system of the academy theatre for keeping the section procedure. In this assignment I used entity relationship diagram and other demands and processs. Recommendation: Harmonizing the users demands and after probe the system, I could happen out some jobs and some other job in the college development diagram. The keeping system of the college development diagram was really hard to pull off. To work out the jobs I provide the new IT system. I will seek and bring forth the really easy manner to pull off the college development diagram for keeping procedure or systems in the new database system of College Database Development. Requirement hardware: To set up the procedure some hardware and package are really indispensable. The name or hardware demands are given in the followers: Personal computer ( Include all hardware ) Network Connection SQL waiter Windows XP .NET model Future program for my database: In the assignment I produced a database direction system for a college section. There are many sections of the college. I will include more information about more sections in the database at future. To implement my database I will utilize latest tools. I will seek to happen how manner I can implement the database. Appendix: Entity Relationship Diagram ( ERD ) : Optimization diagram: Database Summary: There are five undertakings in the assignment. The assignment contains some subjects of database. As a pupil any one can larn about database direction system from the topic. The undertaking five contains information of an premise. In the undertaking I tried to supply an ideal premise about the whole assignment. How to cite Entity Relationship Diagram Analysis, Essay examples
