1.数据库：
数据库是使用称为数据库管理系统(DBMS)的软件包以有组织的方式存储在包含行和列的表中的数据的集合。
DBMS用于修改，定义，操作和管理数据。 DBMS的一些示例是：MySQL，Oracle数据库和Microsoft Access。
2.数据结构：
在计算机程序设计中，数据结构是一种组织和存储数据以简化数据访问和修改的方式。
存在用于存储数据的各种类型的数据结构，并且不同的数据结构具有不同且独特的特征。
一些常用的数据结构是数组，链接列表，堆栈，队列，堆，二叉树和图。
数据库和数据结构之间的区别：
| Database | Data Structure |
|---|---|
| It is an organized collection of data. | It is a special format for storing data to serve a particular purpose. |
| It is used to access the data and manage it easily. | It is used for efficiency and to reduce the complexities of the program. |
|
Structured query language (SQL) is used to perform operations on the data in a database. DataBase Management System (DBMS) is used to manage the database. |
Programming languages like C, C++, Java, Python are used to perform operations using data Structures. |
| It is a Non-volatile memory. | It is a volatile memory. |
| Relational database, NOSQL database, Centralized database, Hierarchical database are some types of databases. | Linear data structure and non-linear data structure are the types of data structures. |
| Example : MySQL, Oracle, MongoDB, Sybase etc. | Example : Array, Linked List, Stack, Queue, Tree, Graph. |
