The basic difference between DDL and DML is the commands they provide . The dml (data manipulation language) provides statements to enter, update, delete and perform complex queries on these tables while the ddl(data description language) provides statement for the creation and deletion of tables, indexes, views etc.
The DDL provides statement for the creation and deletion of tables, indexes, views etc. The DML provides statements to enter, update, delete and perform complex queries on these tables.
DML(data manipulation language) provides statements to enter, update, delete and perform complex queries on these tables. DDL(Data definition language) provides statements for creation and deletion of tables, view, indexes etc.
dml processor process the dml statements such as select,update,delete etc that are passed by the application programmer into a computer program that perform specified task by programmer such as delete a table etc.

You can manipulate data in a database by using the DML - Data Manipulation Language statements. These include:InsertUpdate andDeleteBy using these 3 statements you can manipulate the data in a database.

What is difference between Compiler and DML Compiler
Update and Alter are two SQL (Structured Query Language) commands used for modifying databases. Update statement is used to update existing records in a database. Update is a Data Manipulation Language (DML) statement. Alter SQL command is used to modify, delete or add a column to an existing table in a database. Alter is a Data Definition Language (DDL) statement.Commands that are used to define the structure of a database (database schema) are called DDL statements.
