Presentations do not have data-types, you might have misunderstood somethings.
There are four types of commands in Structured query language. One of the four type of command includes data definition language. Data definition language includes create , delete , drop command .
SQL (Structured Query Language) is commonly used to create and interact with databases. It is a specialized language for managing and manipulating data stored in relational database management systems. With SQL, you can define the structure of a database, create tables, insert, update, and query data stored in those tables.
Different languages have different data types. But basically, each class can be considered a different data type. For example, if a language doesn't have a data type for dates, create a class, with fields (or properties) to store day, month, year; if your language doesn't have complex numbers, create a class with two fields of some real type to store the real and the imaginary part; if your language doesn't have a data type to store information about a font (its name, size, and characteristics like being or not being bold), create a class to save information about a font, etc.Different languages have different data types.

In the Excel program, a data point is a point of reference. They are used to highlight or mark specific sections or areas. To create a data point you need to click on the first section you wish highlighted, click the second point of reference then label it.
Different type of data definition language are there. generally they are 1-Create 2-Alter 3-Truncate 4-Comment 5-Rename 6-Drop.
DDL statements -Data Definition Language It is used to Retrive,Store,Modify,Delete,Insert,update data in database. 1) Create 2) Alter 3) Drop DML Statements.-Data Manipulation Languag It is used to create and modify the structure of database objects in database. 1) Insert 2) Update 3) Delete 4) select DCL statements-Data Control Language It is used to create roles, permissions, and referential integrity as well it is used to control access to database by securing it. 1) GRANT 2) REVOKE TCL-Transactional Control Language It is used to manage different transactions occurring within a database. 1) COMMIT 2) ROLLBACK 3) Save point DQL-Data Query Language basicallu used for select data from table... 1) SELECT
data manipulation language, belongs to databases and sql. queries like insert/update/delete. in contrast, queries like create/alter/drop are called ddl (data definition language)
A table in database can be created using create table command . Create command comes under data manipulation language.
a computer language by wch a programme can run and
DDL - Data Definition Language Create,Alter,Drop and Truncate are the components of oracle database.
The people who create the language take the liberty of deciding the size of data types in a programming lanauage.If you (as a programmer) create your own custom data type, for example by defining a class, then you decide what goes into it - for example, in Java, if one of the pieces of data requires an integer, you have the choice of storing it as an int, which uses 4 bytes, or as a long, which uses 8 bytes (and permits larger numbers).
