"Convention over Configuration," often abbreviated as "CoC," is a principle in software development that suggests that in a software framework or development environment, default configurations and conventions should be preferred over explicit configurations. In other words, if developers adhere to certain naming conventions and structures, they should be able to develop their software without extensive configuration.
The "Convention over Configuration" principle has several advantages:
Simplified Development: Developers need to worry less about configuring software components. Instead, they simply follow the established conventions, making development faster and smoother.
Consistency: Since all developers on the team use the same conventions, this leads to a more consistent codebase, which facilitates collaboration and maintenance.
Avoiding Redundancy: Conventions can help avoid redundancy in configuration. Instead of having to configure specific settings for each part of the application, developers can rely on default configurations.
Clarity: Adhering to conventions makes the code more understandable for developers, as they know where to find specific parts of the application or configuration.
A well-known example of "Convention over Configuration" can be found in the Ruby on Rails framework, which uses default naming conventions for database tables, models, controllers, and views. By following these conventions, a developer can build a database-backed web application without manually configuring database tables or routes.

Relational databases are a type of database management system (DBMS) based on the relational database model. This model organizes data into tables (also called relations) that are structured in rows and columns. The concept of relational databases was first developed by Edgar F. Codd in the 1970s and has since become one of the most commonly used approaches for storing and managing structured data.
Here are some fundamental concepts and features of relational databases:
Tables: Data in relational databases is organized into tables. Each table has columns representing specific data types and rows representing individual records. Each row in the table is referred to as a tuple.
Schema: The schema of a relational database defines the structure of the tables, including table names, column names, and their data types. It also establishes relationships between tables.
Primary Key: Typically, each table in a relational database has a column or a combination of columns that serve as the primary key. The primary key is unique for each row in the table and is used to identify records.
Foreign Key: Relationships between tables are established using foreign keys. A foreign key is a column in one table that references the primary key of another table, allowing for linking records in different tables.
SQL (Structured Query Language): Querying and manipulating data in relational databases is typically done using SQL. SQL provides a standardized way to query, update, and manage data.
Consistency and Integrity: Relational databases place a strong emphasis on maintaining data consistency and integrity. This is achieved through rules and constraints defined in the database schema to ensure data remains correct and free from contradictions.
Transactions: Relational databases support transactions, which enable a group of database operations to be either fully completed or not at all. This contributes to data consistency and integrity.
Relational databases are used in a wide range of applications, from managing enterprise data to storing user information in web applications. They are particularly well-suited when structured data needs to be organized in tabular form, and complex queries and relationships between data are required. Well-known relational database management systems include MySQL, PostgreSQL, Oracle Database, and Microsoft SQL Server.
