Answer: A) Database design and structure
A Schema is the overall design and structure of a database. It defines how data is organized and how different database objects are related to each other.
A database schema describes elements such as:
* Tables: Where data is stored.
* Fields (Columns): What type of information is stored in each table.
* Relationships: How different tables are connected.
* Constraints: Rules that maintain the accuracy and consistency of data.
For example, in a school database, there may be separate tables for Students, Teachers, and Subjects. The schema defines the structure of these tables and how they are connected.
Schema भनेको Database को समग्र डिजाइन र संरचना हो। यसले Database भित्र Data कसरी राख्ने, कुन-कुन Table बनाउने, Table मा कस्ता Field राख्ने र विभिन्न Table हरूबीच कस्तो सम्बन्ध हुने भन्ने कुरा निर्धारण गर्छ।
उदाहरणका लागि, एउटा School Database मा Students, Teachers र Subjects का लागि छुट्टाछुट्टै Table हुन सक्छन्। यी Table हरूमा कुन-कुन Field राख्ने र एकअर्कासँग कसरी सम्बन्धित हुने भन्ने जानकारी Database Schema ले निर्धारण गर्छ।
त्यसैले Schema ले Database को सम्पूर्ण बनावट र डिजाइनलाई जनाउँछ।
