Database schema design — sometimes called SQL schema design — refers to the practices and strategies for constructing a database schema. You can think of database schema design as a blueprint for storing massive amounts of information in a database. The schema is an abstract structure or outline representing the logical view of the database as a wh...
Inefficiently organized databases suck up tons of energy and resources and are difficult to maintain and administer. That’s where database schema design comes into play. You’ll struggle to get value from enterprise data without a clean, efficient, consistent database schema. The right schema design removes duplicated and inconsistent data in differ...
Database schemas outline the architecture of a database and ensure database fundamentals such as the following: 1. Data has consistent formatting 2. All record entries have a unique primary key 3. You don't omit important data A DB schema design can exist both as a visual representation and as a set of formulas or use constraints that govern a data...
To make the most of database schema design, it’s important to follow best practices. That ensures developers have a clear reference point for tables and fields in a project. Here are some of those best practices: Naming Conventions 1. Define and use appropriate naming conventions to make your database schema designs more effective. While you may de...
DB schema design organizes data into separate entities, determines how to create relationships between organized entities, and influences the applications of constraints on data. Designers create database schemas to give other database users, such as programmers and analysts, a logical understanding of data. Why Is Database Schema Design Important?
Flat model: A flat model database schema organizes data in a single, two-dimensional display—think of a Microsoft Excel spreadsheet or a CSV file. This schema is best for simple tables and databases without complex relationships between different entities.
Basic Architecture of Twitter service consists of a User Table, Tweet Table, and Followers Table When a user tweets it gets stored in the Tweet Table along with User ID. User Table will have 1 to many relationships with Tweet Table When a user follows another user, it gets stored in Followers Table, and also cache it Redis
Star schema: The star schema is an evolution of the relational model that organizes data into facts and dimensions. Fact data is numerical (for example, the number of sales of a product), while dimensional data is descriptive (for example, a product’s price, color, weight, etc.).
