What is a SQL Injection?
When your website is data-driven, SQL Injection can become an attack vector of immense consequence. Through its vulnerabilities, attackers gain the ability to inject code directly into your database control plane in order to execute commands they would have difficulty doing otherwise. A successful attack could allow attackers access to user lists, table deletion or

What are Views in SQL?
Views in SQL are virtual tables created on top of tables within a database, used to disguise complex select queries from end-users or applications and restrict access to specific columns or rows within tables; providing an extra layer of security by only showing data that meets certain criteria to users. Views may also reduce the

What is Normalization in SQL?
Normalizing databases reduces redundancy, improves data consistency and simplifies query performance while simultaneously increasing storage space and query complexity. In this article we will look at what normalization is and its various forms, as well as why its importance. Normalizing databases serves to reduce redundancy by isolating related information into separate tables. This ensures that

What is SQL in DBMS?
SQL is a programming language designed to manage relational database data. It consists of three parts, such as Data Definition Language (DDL), Data Manipulation Language (DML), and Transaction Control Language (TCL). Data stored in relational database systems is typically organized into tables linked by relationships; SQL statements can then be used to manipulate this information

What are Constraints in SQL?
SQL is an extremely versatile language for creating databases. It enables users to construct tables containing information that adheres to a range of business rules, and which can easily be retrieved from the database. To ensure insertions, updates, or deletions adhere to these rules without disrupting integrity, SQL Constraints have been placed upon tables/columns in

What is Schema in SQL?
A schema in SQL is the logical arrangement of database objects such as tables, views, stored procedures, indexes and constraints that form part of any relational database management system (RDBMS). A poorly designed schema can have severe adverse impacts on its performance.
