Database Architecture (2024)

FAQs

How to create a database of questions and answers? ›

Storing a quiz in a database involves creating tables to represent different aspects of the quiz, such as questions, answer options, and correct answers. Below is a simplified example using SQL and assuming a relational database structure. In practice, the database design may vary based on specific requirements.

One – Tier Architecture

It means that the user interface, business, layers are accessible by the application under the same local drive. Both the client and server reside in the same machine. It is the simplest application architecture used.

Explanation: A database's architecture can be viewed as the three levels of abstraction that are named as the internal level, external level, and the conceptual level. Therefore the correct answer is C.

A database is an organized collection of structured information, or data, typically stored electronically in a computer system. A database is usually controlled by a database management system (DBMS).

Select Databases from the SQL navigation menu. Click Create database. In the New database dialog, specify the name of the database. Click Create.

For creating a Quiz App, we prefer an SQLite database; it is a host-driven database and can't be accessed elsewhere.

Data Analysis is a method of getting answer to question about data.

A query can be a request for data results from your database, or it can be used to perform an action on the data, or it might be both. Use queries to get answers to simple questions, perform calculations using data, combine data from different tables, and add, change, or delete data from a database.

The term "database architecture" refers to the structural design and methodology of a database system, which forms the core of a Database Management System (DBMS). This architecture dictates how data is stored, organized, and retrieved, playing a crucial role in the efficiency and effectiveness of data management.

What is a 3 tier architecture in DB? ›

Three-tier architecture is a well-established software application architecture that organizes applications into three logical and physical computing tiers: the presentation tier, or user interface; the application tier, where data is processed; and the data tier, where application data is stored and managed.

A key refers to an attribute/a set of attributes that help us identify a row (or tuple) uniquely in a table (or relation). A key is also used when we want to establish relationships between the different columns and tables of a relational database.

Requirements Gathering. The first step is requirements gathering. During this step, the database designers have to interview the customers (database users) to understand the proposed system and obtain and document the data and functional requirements.

The ANSI-SPARC database architecture is the basis of most of the modern databases. The three levels present in this architecture are Physical level, Conceptual level and External level.

Choose the option on which database architecture is based. Answer - B) Database architecture is based on RDBMS.

The Question bank allows a teacher to create, preview and edit questions in a database and use them in the Quiz (or selected ones in a Lesson) activity. Questions are organized in categories and subcategories similar to the way files are stored in folders and subfolders.
