Databases are used to store data. In a relational database, data is organized into tables. A table is a collection of rows, and each row is a collection of columns. SQL Server is a relational database management system (RDBMS) developed by Microsoft. SQL Server is a client-server database system, meaning that it is a database that is accessed by clients. SQL Server provides two primary services: data definition language (DDL) and data manipulation language (DML). DDL is a language used to define the structure of a database. DDL statements are used to create, modify, and delete database objects. DML is a language used to manipulate data in a database. DML statements are used to insert, update, and delete data in a database.
DDL and DML are the two main types of SQL Server queries. DDL, or Data Definition Language, is used to create and modify database objects such as tables, indexes, and constraints. DML, or Data Manipulation Language, is used to insert, update, and delete data in the database.
In conclusion, DDL and DML in SQL Server Services are two very important things to know about when working with databases. DDL allows you to create and modify database structures, while DML lets you manipulate data within those structures. Knowing how to use both of these can help you get the most out of your database and make working with it a breeze.
