Network DDL (Data Definition Language) refers to a set of SQL commands used to define and manage the structure of a network database. It includes operations for creating, altering, and deleting database objects such as tables, indexes, and relationships within a network model. Unlike traditional relational databases, network databases use a more flexible structure that allows for complex many-to-many relationships, making DDL in this context essential for establishing those connections. Overall, Network DDL helps define how data is stored and accessed in network database systems.
DDL stands for Data Definition Language, and so it follows that creating a table is DDL, creating a view is DDL and so on.
Full form of the DDL is Data Definition Language.
ddl stands for Data Definaton Language.Eg:- Create ,Alter .Drop.Truncate Why we have called it as DDL means.... we are defining or acting at structure level. Say, when ever you create a table we are dealing at strucutre level. Hence its is DDL
ddl: data definition languagedml: data manipulation language
DDL compiler is the compiler whose job is to convert high level commands to low level commands..

DDL Interpreters are computer programs designed to process and execute Data Definition Language (DDL) statements. These statements are used to create, modify, and delete database structures such as tables, indexes, and constraints. DDL Interpreters play a crucial role in managing the database schema and ensuring data integrity.
no, they are free
Some of the operations performed in DDL in sql are creation of table,alteration of table,truncate a table, drop a table
The basic difference between DDL and DML is the commands they provide . The DDL provides statement for the creation and deletion of tables, indexes, views etc. while the DML provides statements to enter, update, delete and perform complex queries on these tables.
