It used structureER Model is used to model the logical view of the system from data perspective which consists of these components:. An Entity may be an object with a physical existence — a particular person, car, house, or employee — or it may be an object with a conceptual existence — a company, a job, or a university course.
An Entity is an object of Entity Type and set of all entities is called as entity set. In ER diagram, Entity Type is represented as:. Attribute s : Attributes are the properties which define the entity type. In ER diagram, attribute is represented by an oval. Multivalued Attribute — An attribute consisting more than one value for a given entity.
In ER diagram, multivalued attribute is represented by double oval. The complete entity type Student with its attributes can be represented as:. Relationship Type and Relationship Set: A relationship type represents the association between entity types. In ER diagram, relationship type is represented by a diamond and connecting the entities with lines. A set of relationships of same type is known as relationship set. Degree of a relationship set: The number of different entity sets participating in a relationship set is called as degree of a relationship set.
Cardinality: The number of times an entity of an entity set participates in a relationship set is known as cardinality. Cardinality can be of different types:. Using Sets, it can be represented as:. So it is many to many relationships. Participation Constraint: Participation Constraint is applied on the entity participating in the relationship set.
Every student in Student Entity set is participating in relationship but there exists a course C4 which is not taking part in the relationship. Weak Entity Type and Identifying Relationship: As discussed before, an entity type has a key attribute which uniquely identifies each entity in the entity set.
These are called Weak Entity type. For example, A company may store the information of dependants Parents, Children, Spouse of an Employee. A weak entity type is represented by a double rectangle. The participation of weak entity type is always total.
The relationship between weak entity type and its identifying strong entity type is called identifying relationship and it is represented by double diamond. Article Contributed by Sonal Tuteja.

For example, consider office department in school maintains details of the student such as name of the student, age, address, class etc.
These all records are related with student stored in a database. Database management System is collection of data and set of programs to access the data. It allows creation, definition and manipulation of database. DBMS provides protection and security to database. DBMS is used by many users for various purposes. In large organizations, many people are involved in design, use and maintenance of database with hundreds of users.
The people whose job is to maintain day-to-day use of large database, we call them as actors on the scene. Some of them are described as follows :. A client in this framework is a user machine which provides user interface and local processing. The second approach i. The server level may include data storage on disk pages, recovery and buffering of disk pages and other functions.
The client level may include user interface, interaction with programming language compiler, recovery across multiple servers and other functions. It is simplicity and compatibility with existing system. An end user sits on client tier i. All views are generated by applications which reside in the application tier. The middle layer sometimes called application server or sometimes web server depending on the application. This tier is uses business roles that are used to access data from the server.
For user application tier works as view of the database. The intermediate tier accepts requests from the client, processes the request and sends the commands to database server.A crew of people will be controlled by a captain. In a vessel,the captain has the right to give commands.
Vessel can be a SOTL. Many regions are patrolled by vessels and many vessels patrols many regions to make sure that there is no trouble there. You are commenting using your WordPress.

Check out other projects in vb 6. Using the E-R Diagram we can create a relational model of the database.
It means we can create tables with the database. To create a new database go to the Microsoft Access Database and create a new blank database.

If you have MS Access or Higher save the database with. Otherwise, Visual Basic 6 may not recognize the database file. Create three four tables within the database with appropriate data-types given in the following figures. Most of the forms in the application need to connect to the database, so you may have to write code for connectivity with Microsoft Access Database repeatedly in each form. Instead of writing the code for connectivity in each form, we write it once in a Module and call the function from the form.
In this way, we save time to write the same code many times. Vote count: 0 No votes so far! Be the first to rate this post.

The Entity-Relation model represents real-world entities and the relationship between them. It is considered a best practice to complete ER modeling before implementing your database. So, it is considered a best practice to complete ER modeling before implementing your database.
In this tutorial, you will learn- What is the ER Model? Why use ER Diagrams? It was proposed by Peter Chen in to create a uniform convention which can be used for relational database and network.
He aimed to use an ER model as a conceptual modeling approach. What is ER Diagrams? In other words, we can say that ER diagrams help you to explain the logical structure of databases.Entity Relationship Diagram Explain in Tamil - Rajaram Sam Tamil Programmer.
At first look, an ER diagram looks very similar to the flowchart. However, ER Diagram includes many specialized symbols, and its meanings make this model unique. The purpose of ER Diagram is to represent the entity framework infrastructure. Here, are prime reasons for using the ER Diagram Helps you to define terms related to entity relationship modeling Provide a preview of how all your tables should connect, what fields are going to be on each table Helps to describe entities, attributes, relationships ER diagrams are translatable into relational tables which allows you to build databases quickly ER diagrams can be used by database designers as a blueprint for implementing data in specific software applications The database designer gains a better understanding of the information to be contained in the database with the help of ERP diagram ERD is allowed you to communicate with the logical structure of the database to users Components of the ER Diagram This model is based on three basic concepts: Entities Attributes Relationships Example For example, in a University database, we might have entities for Students, Courses, and Lecturers.
They might have relationships with Courses and Lecturers.
Bank Project ( Entity Relationship Diagram)
A real-world thing either living or non-living that is easily recognizable and nonrecognizable. It is anything in the enterprise that is to be represented in our database. It may be a physical thing or simply a fact about the enterprise or an event that happens in the real world. An entity can be place, person, object, event or a concept, which stores data in the database. The characteristics of entities are must have an attribute, and a unique key.
Every entity is made up of some 'attributes' which represent that entity. It may contain entities with attribute sharing similar values. Entities are represented by their properties, which also called attributes.
All attributes have their separate values. For example, a student entity may have a name, age, class, as attributes. Example of Entities: A university may have some departments. All these departments employ various lecturers and offer several programs. Some courses make up each program. Students register in a particular program and enroll in various courses. A lecturer from the specific department takes each course, and each lecturer teaches a various group of students.
Relationship Relationship is nothing but an association among two or more entities. Entities take part in relationships. We can often identify relationships with verbs or verb phrases.Entity-Relation design will depend on the notion of real-entire world entities and also the relationship between them.
ER modeling allows you to examine data needs systematically to generate a nicely-made data bank. So, it is actually considered a greatest training to perform ER modeling prior to implementing your database. ER diagrams are a aesthetic instrument that is helpful to stand for the ER model. It absolutely was suggested by Peter Chen in to make a standard convention which can be used relational database and system. He targeted to make use of an ER product as a conceptual modeling method.
Entity relationship diagram shows the relationships of entity set kept in a data bank. Quite simply, we can easily claim that ER diagrams help you to make clear the plausible construction of databases. In the beginning look, an ER diagram looks nearly the same as the flowchart. Nevertheless, ER Diagram consists of many specialised signs, as well as its connotations make this version exclusive. An actual-community thing possibly living or low-dwelling which is very easily recognizable and nonrecognizable.

It is actually nearly anything from the enterprise that will be represented in your data bank. It may be a physical thing or simply a simple fact in regards to the enterprise or perhaps an occasion that takes place in real life. An entity could be position, individual, item, celebration or perhaps a concept, which shops information inside the data base. The attributes of entities are must have an attribute, plus a special key. Relationship is absolutely nothing but a connection among 2 or more entities.
Entities be a part of partnerships. We can typically identify partnerships with verbs or verb words. It might be identified uniquely by taking into consideration the major important of another entity. For this, poor entity collections need to have involvement.
