Logetc. In a typical ER design, you can find symbols such as rounded rectangles and connectors with different styles of their ends that depict the entities, their attributes, and inter-relationships.

When determining entities, think of them as nouns. In ER models, an entity is shown as a rounded rectangle, with its name on top and its attributes listed in the body of the entity shape.

Also known as a column, an attribute is a property or characteristic of the entity that holds it. An attribute has a name that describes the property and a type that describes the kind of attribute it is, such as varchar for a string, and int for integer. Also known as PK, a primary key is a special kind of entity attribute that uniquely defines a record in a database table. In other words, there must not be two or more records that share the same value for the primary key attribute.

The ERD example below shows an entity 'Product' with a primary key attribute 'ID', and a preview of table records in the database.An entity relationship diagram ERD shows the relationships of entity sets stored in a database. An entity in this context is an object, a component of data. An entity set is a collection of similar entities. These entities can have attributes that define its properties.

By defining the entities, their attributes, and showing the relationships between them, an ER diagram illustrates the logical structure of databases. There are two reasons to create a database diagram. You're either designing a new schema or you need to document your existing structure. If you have an existing database you need to to document, you create a database diagram using data directly from your database. You can export your database structure as a CSV file there are some scripts on how to this herethen have a program generate the ERD automatically.

This will be the most accurate potrait of your database and will require no drawing on your part. If you want to create a new plan, you can also edit the generated diagram and collaborate with your team on what changes to make.

Here is the data set description:. Which stadium is best suitable for first batting. Here we evaluate that which stadium is most suitable for first batting. Here are the details how can we do that. Here is the scala code to do that. In the first line of code we are loading the data from the local file system.

In the second line we are filtering the bad records if any are there i. In the third line we are extracting the columns that are required for our analysis i. Here is the screen shot of the whole stack trace. But this is not the final result, we need to evaluate the total number of matches that chidambaram stadium has been venue. Let us see how many matches that each stadium has been venued.
