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).
A database is a systematic collection of data. They support electronic storage and manipulation of data. Databases make data management easy. Let us discuss a database example: An online telephone directory uses a database to store data of people, phone numbers, and other contact details.

Databases are used for storing, maintaining and accessing any sort of data. They collect information on people, places or things. That information is gathered in one place so that it can be observed and analyzed. Databases can be thought of as an organized collection of information.
“Database, also called electronic database, any collection of data, or information, that is specially organized for rapid search and retrieval by a computer. Databases are structured to facilitate the storage, retrieval, modification, and deletion of data in conjunction with various data-processing operations.
Databases are used just about everywhere including banks, retail, websites and warehouses. Banks use databases to keep track of customer accounts, balances and deposits. Retail stores can use databases to store prices, customer information, sales information and quantity on hand.
Four types of database management systems
Within a database, related data are grouped into tables, each of which consists of rows (also called tuples) and columns, like a spreadsheet. To convert your lists of data into tables, start by creating a table for each type of entity, such as products, sales, customers, and orders.
But it impact your daily life very extensively. Your grocery store, bank, restaurant, online shopping sites, hospital, favorite clothing store and mobile service provider, for instance all use databases to keep track of customer, inventory, employee and accounting information.
A personal database is used to store frequently used, unique, or customized information. This provides faster access to targeted information for use across all studies and projects.

A database built to the CDB specification is referred to as a Common Database (CDB) and is a single-copy data repository from which various simulator client-devices are able in real-time to simultaneously retrieve relevant information to perform their respective runtime simulation tasks.

Excel is a great spreadsheet application but, it`s not really a database at all. Excel however is an excellent complement to any database since it can turn row after row of data into attractive and comprehensive reports and charts.
Different types of databases exist: relational, flat file based, hierarchical, network or object-oriented. One of the biggest changes in database design came about in the 2000s, when NoSQL began popularizing the “non-relational database.” In the past, almost all databases were relational.
In order to do so, simply use the 'if exists' method and select the name of the database from sysdatabases. The code below will drop an existing database if it exists so be careful. An alternate method is to use the db_id to convert the db_name and see if it is null.
Amazon RDS facilitates the deployment and maintenance of relational databases in the cloud. A cloud administrator uses Amazon RDS to set up, operate, manage and scale a relational instance of a cloud database. Amazon RDS is not itself a database; it is a service used to manage relational databases.
