DDL stands for Database Definition Language. It is a language used to create a database. Most databases have a language that will do this. Normally it is a form of SQL (Structured Query Language).

The two major types of databases are relational databases and non-relational databases. Relational databases store data in tables with predefined relationships, while non-relational databases use flexible data models like key-value pairs, documents, graphs, or columns.
Traditional databases are designed to store and manage structured data like text and numbers, while multimedia databases are specifically tailored to handle multimedia data such as images, videos, and audio. Multimedia databases use special indexing and retrieval techniques to efficiently manage and retrieve multimedia content, whereas traditional databases rely on more standardized querying methods. Additionally, traditional databases are typically more mature and widely used compared to multimedia databases.
Relational databases: Organize data into tables with rows and columns. NoSQL databases: Designed for large volumes of unstructured or semi-structured data. Object-oriented databases: Store data as objects. Graph databases: Optimal for data with complex relationships. In-memory databases: Data stored in RAM for faster access.
Primary sequence databases contain raw sequence data derived from the sequencing of genes etc. whereas secondary sequence databases contain information that is derived from primary sequence databases. For example this could be active site residues of protein families that were found by carrying out multiple sequence alignments on the raw primary sequence database data for a set of related proteins. Primary sequence databases can be nucleic databases (such as EMBL, GenBank or DDBJ) or protein databases (such as Swiss-PROT or trEMBL). An example of a secondary sequence database is PROSITE.
Distributed database is one logical database which is spread out over multiple sites, connected by network. It behaves as it were a single database. Decentralized databases are a group of independent databases spead out over different locations. They are not connected and do not share updates between each other.
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
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)
The three languages adopted by the Database Task Group (DBTG) are Data Definition Language (DDL), Data Manipulation Language (DML), and Data Control Language (DCL). These languages help define the structure of databases, manipulate data within databases, and control access permissions to the data.
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.
