The purpose of data modeling
is the formalization and documentation of existing processes and events that occur during application software design and development. Data modeling techniques and tools capture and translate complex system designs into easily understood representations of the data flows and processes, creating a blueprint for construction and/or re-engineering.

Advantages of flat data model?
two main early navigational data models were the hierarchical model and the CODASYL model (network model)
What is one purpose of a data table?
To keep track of a lot of data
What is the significance of data models?
The model's main function is to help us understand the complexities of the real-world environment. Within the database environment, a data model represents data structures and their characteristics, relations, constraints, and transformations. Good database design uses an appropriate data model as its foundation. Plus, a data model provides a blueprint of the data that is required for a functional system.
How is the data represented on a scatter plot that depicts an exponential model?
In a scatter plot that is an exponential model, data can appear to be growing in incremental rates. In this type of model the data will only cross the Y-axis at one point.
What is the main purpose of data source?
to gage the authenticity of the data & control mechanism attached to the source to prevent manupulation of data
What is the difference between data model and database model?
A database is a collection of tables that is used for some purpose (typically an application of some sort). A database model is a description of that database, and describes how the tables relate to each other. Typically, a model is designed first, then the actual database is implemented using the model as a blueprint.
What is the purpose of the OSI model?
An OSI, or Open Systems Interconnect, model is a standard industry model that is used to describe how software data moves through a network from one computer to another. It has seven layers that are application, presentation, session, transport, network, data link, and physical.
What is the purpose of a data chart?
the purpose of a data chart is to write your data down by using your chart
Explain data model?
Explain data model?
Define data models and list different types of data models?
A data model is a collection of concepts that can be used to describe the structure of a database and provides the necessary means to achieve this abstraction whereas structure of a database means the data types,relationships and constraints that should hold on the data. Data model are divided into three different groups they are 1)object based logical model 2)record based logical models 3)physical models Types: Entity-Relationship (E-R) Data Model Object-Oriented Data Model Physical Data Model functional data model
What is data model?
In computer science, data modeling is the process of creating a data model by applying a data model theory to create a data model instance. A data model theory is a formal data model description.For the source and more detailed information concerning your request, click on the related links section (Answers.com) indicated below.
What is the lowest data model?
The lowest data model is the physical data model. It represents how data is stored on a specific type of hardware and helps optimize storage and retrieval. It is the closest to the physical implementation in a database system.
What is the purpose of capturing data?
EXC FILE. data
What are the Classification of data model?
Data models can be classified into three main categories: conceptual data model (high-level view of the data and its relationships), logical data model (detailed structure of the data and relationships), and physical data model (implementation of the database design on a specific database management system).
How is data collected and used for the purpose of national statistics?

What Data model is said to be a semantic data model?
An Entity-Relationship (ER) model is commonly referred to as a semantic data model. It focuses on defining the entities, attributes of the entities, and the relationships between entities to capture the meaning of data in a domain. This model helps to visualize and understand the semantics of the data being represented.
What is the purpose of a Gmod?
The purpose of Generic Model Organism Database (GMOD) is to create a small laboratory database of genome annotations, or a large web-accessible community database. It is responsible for visualizing, annotation and managing data.
