Data Modelling Using The ER ModelIf you want to learn more check out How do you know if a function is linear or nonlinear?

  • The term database application refers to a particular database and the associated programs that implement the database queries and updates.
  • The Entity-relationship (ER) model is a popular high-level conceptual data model.
  • Diagrammatic notation associated with the ER model is known as ER diagram.

We also discuss several other topics like How did president carter attempt to arbitrate between brzezinski and vance?

High-Level Conceptual Data Models for Database DesignWe also discuss several other topics like Why do you think the movie insists in framing the political message on debates that took place during the sixteenth century?

  • The database design process is,
  • First Step: - Requirement collection and Analysis

During this step, database designers interview prospective database users to understand and document their data requirements.

  • Along with data requirements and functional requirements are also captured which consists of operations/transactions that will be applied to the database - i.e. retrieval and updates
  • Data flow diagrams, sequence diagrams, scenarios and other techniques are used to specify functional requirements.
  • Next Step: -create conceptual schema for the DB using high-level conceptual data model.

This step is called conceptual design.

  • Conceptual schema includes entity types, relationships and constraints
  • High level conceptual schema is used to ensure all user requirements are met and do not conflict.
  • After conceptual schema design, basic data model operations are used to specify high-level user operations and queries specified in the functional analysis.
  • Next step: - Actual Implementation of database: -Implementation data model-relational, model is used to transform high level data model to implementation data model.

This step is called Logical Design  or Data Model Mapping.

  • Last Step: -Physical Design Phase

Internal storage structure, file organizations, indexes, access paths and physical design parameters for database files are specified.

  • Application programs are designed and implemented as database transactions corresponding to the high-next-level transaction specifications.

Entity Types, Entity sets, Attributes and Keys

  • The ER model describes data as entities, relationships and attributes.

Entity and Attributes:-Don't forget about the age old question of What are the three driving principles of elizabethan poor law 1601?

        Entity is a string of objects in the real world with an independent existence.

Entity has attributes - particular properties that describe it. Attribute describe each entity and become a major part of data stored in DB.Don't forget about the age old question of What are the steps in balancing reactions in stoicheometry?

  • Several types of attributes occur in ER Model.

  1. Composite vs. Simple (Atomic) Attributes
  • Composite attributes can be divided into smaller subparts - which represent more basic attributes with independent meanings.

e.g. : - Addresses are subdivided into street-address, city, state and zip.

  • Attribute that are not divisible are called simple or atomic attributes
  • Composite attributes can form a hierarchy.

E.g. Street-address can be subdivided into three simple components: Number, street, Apartment number.

  1. Single-Valued versus Multivalued Attributes
  • Attributes that have a single value for a particular entity are called single-valued.

e.g. Age is single-valued.

  • Some attributes can have a set of values for the same entity, such attributes are called multivalued.
  • Multivalued attributes can have lower and upper bounds to constrain the number of values.

  1. Stored vs. Derived Attributes
  • Value of Age can be determined from the current date and the value of the person's Birth-date. The Age attribute is hence called a derived attribute, and is derivable from Birth-date attribute, which is called a stored attribute.

  1. Null values -
  • In some cases, a particular entity may not have an applicable value for an attribute.

e.g. - college-degrees attribute applies only to people with college degrees, for such situations, a special value called NULL is created.
