These four operations are used to manipulate the data in database, users must be able to create data, read data, update or edit the data, and delete the data. curd<\/strong> sometimes used to describe user interface conventions that facilitate viewing, searching, and changing information using computer-based forms and reports.<\/p>\n\n\n\n curd<\/strong> is extensively used in database applications. This includes Relational Database Management Systems <\/strong>(RDBMS) like oracle, mysql, and postgresql. It also includes nosql databases like mongodb, apache cassandra, and AWS dynamodb.<\/p>\n\n\n\n create<\/strong>\u00a0operation adds a new record to a database, in RDBMS, a database table row are called record and columns are called fields. Create operation adds one or more new records with distinct field values in a table. in sql database, to create is to\u00a0Insert and in a nosql database like mongodb, you create with the\u00a0 update<\/strong>\u00a0is the operation that allows you to modify existing data.
