What is Data Modeling? IBM

5 hours ago Ibm.com Show details

1. Data modeling is the process of creating a visual representation of either a whole information system or parts of it to communicate connections between data points and structures. The goal 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 attributes. Data models are built around business needs. Rules and requirements are defined upfront through feedback from business stakeholders so they can be incorporated into the design of a new system or adapted in the iteration of an existing one. Data can be modeled at various levels of abstraction. The process begins by collecting information about business requirements from stakeholders and end users. These business rules are then translated into data structures to formulate a concrete database design. A data model can be compared to a roadmap, an architect’s blueprint or any formal diagram that facilitates a deepe...

Frequently Asked Questions

How is data modeling used in database design?

Data modeling is a method of creating a data model for the data to be stored in a database. It conceptually represents data objects, the associations between different data objects, and the rules. Data design tools help you to create a database structure from diagrams, and thereby it becomes easier to form a perfect data structure as per your need.

How are logical and physical models used in data modeling?

The logical model defines how the model should be implemented. It broadly includes all kinds of data that need to be captured such as tables, columns, etc. This model is generally designed by Business Analysts and Data Architects. The physical model defines how to implement a data model with the help of the database management system.

What are the objectives of database design in DBMS?

The database designer decides how the data elements correlate and what data must be stored. The main objectives of database design in DBMS are to produce logical and physical designs models of the proposed database system. The logical model concentrates on the data requirements and the data to be stored independent of physical considerations.

How is model driven database design used in MySQL?

Model-driven database design is an efficient methodology for creating valid and well-performing databases, while providing the flexibility to respond to evolving data requirements. Models are used to build EER diagrams and physical MySQL databases.
