Database Application Technologies Tutorial Answers37

Introduction
Database applications are software programs that allow users to create, manage, and access data stored in a database. They are used in a wide variety of industries, including business, education, healthcare, and government.
There are many different types of database applications, each with its own unique set of features and capabilities. Some of the most common types of database applications include:
* Relational database management systems (RDBMSs): These are the most common type of database application. They store data in a structured format, using tables and columns. RDBMSs provide a variety of features for managing and accessing data, including data definition language (DDL), data manipulation language (DML), and query language.
* NoSQL database management systems (NOSQL DBMSs): These are a newer type of database application that is designed to handle large amounts of unstructured data. NOSQL DBMSs do not use the traditional table and column structure of RDBMSs. Instead, they use a variety of different data models, such as key-value stores, document stores, and graph databases.
* Object-oriented database management systems (OODBMSs): These database applications store data in the form of objects. Objects are data structures that can contain both data and methods. OODBMSs provide a variety of features for managing and accessing objects, including inheritance, polymorphism, and encapsulation.
Database Application Technologies
There are a number of different database application technologies that can be used to create database applications. Some of the most common technologies include:
* SQL (Structured Query Language): SQL is a standard language for accessing and manipulating data in a relational database. It is used to create, update, delete, and retrieve data from a database.
* NoSQL (Not Only SQL): NoSQL is a term used to describe a variety of database technologies that are not based on SQL. NoSQL technologies are often used to handle large amounts of unstructured data.
* XML (Extensible Markup Language): XML is a standard language for representing data in a structured format. XML is often used to exchange data between different applications.
* JSON (JavaScript Object Notation): JSON is a lightweight data format that is often used to represent data in web applications. JSON is similar to XML, but it is more compact and easier to parse.
