Data Modeling and Network Model in DBMS

The ______ can be retrieved by traversing the whole tree starting from the root.

Data modeling is the process of creating a visual representation of either a whole information system or parts of it to communicate connections between ______ points and structures.

The goal of the Network Model is to illustrate the types of data used and stored within the system, the relationships among these data types, the ways the data can be grouped and organized and its formats and ______.

Network Model in DBMS is a hierarchical model that is used to represent the many-to-many relationship among the database ______.

The object-oriented model envisions entities as ______.

Ideally, data models are living documents that evolve along with changing ______ needs.

Data modeling is the first step in designing a ______

Data models are a vital data architecture component, along with flow diagrams, architectural blueprints, a unified vocabulary, and other ______

It facilitates interaction between the designer, the application programmer, and the ______

It allows a better understanding of a particular organization for which the database is intended to be ______

A data model is a visual representation of a real-world data ______

Flat File Model is a database model that utilizes a single table ______

The 'objects' involved are abstractions of real-world entities.Objects are grouped in class hierarchies, and have associated features.IMPORTANCE OF ______ MODEL 1.Data modeling help establish standard data definitions and internal data standards, often in connection with governance. 5 Object-oriented databases can incorporate tables, but can also support more complex data relationships.This approach is employed in multimedia and hypertext databases as well as other use cases People also call these types of diagrams ER diagrams and Entity Relationship Models.An ERD visualizes the relationships between entities like people, things, or concepts in a database. 5.Relational Model The relational model views a database as a set of tables with columns and rows.Each table represents an entity or a data source.Each row is an instance of that entity.ERD Components Keys uniquely identify such rows.And each column is the attribute or property of the entity. 1.Entity ACID Person, Place, Thing, or event that we want to store information about. Denoted by a NOUN. Represented by a rectangle shape in the ERD.Atomicity - Atomic transactions in a ______ setting mean the entire process must finish, or else the file, document, transaction or database reverts to its prior state. 2.Relationship describes the relationship between two entities. denoted by a VERB (passive or active) represented by a diamond shape In the ERD.
