Embedded Data Manipulation Language (EDML) is a programming language that allows developers to embed data manipulation commands directly into the code of an application. This means that the code can interact with a database system by executing commands such as SELECT, INSERT, UPDATE, and DELETE statements without the need for an external program or tool. EDML is often used in the development of database-driven applications, where data is the core of the application. By embedding data manipulation commands in the code, developers can build powerful and flexible applications that can interact with the database system in real-time. EDML commands are executed by a database management system (DBMS) and are used to access, modify and retrieve data stored in a database. These commands can be written in the same programming language as the application code, or in a language specific to the DBMS being used. Overall, EDML is an important tool for developers who need to build database-driven appl...

Interactive Data Manipulation Language (IDML) is a type of programming language that allows users to interactively manipulate and retrieve data from a database system. IDML commands are used to retrieve, insert, modify, and delete data stored in a database. IDML is often used by end-users who do not have programming experience, as it provides a user-friendly interface for data manipulation. IDML commands are executed in real-time, allowing users to view the results of their queries immediately. Examples of IDML commands include SELECT, INSERT, UPDATE, and DELETE statements. The SELECT statement is used to retrieve data from one or more tables in a database, while the INSERT statement is used to insert new data into a table. The UPDATE statement is used to modify existing data in a table, and the DELETE statement is used to remove data from a table. Overall, IDML is an essential tool for data analysts, business intelligence professionals, and end-users who need to access and manipulate ...

Data Definition Language (DDL) is a set of SQL commands used to define and manipulate the structure of database objects such as tables, views, indexes, and sequences. It is a type of programming language that is used to create, modify, and delete database objects in a database management system (DBMS). DDL statements are used to define the schema of a database, which includes the data types of each field in a table, primary and foreign key constraints, and any other constraints on the data. DDL commands include CREATE, ALTER, and DROP statements. CREATE statements are used to create new database objects, ALTER statements are used to modify the structure of existing objects, and DROP statements are used to delete objects from the database. Overall, DDL plays an important role in the management and maintenance of a database by allowing database administrators to define and modify the database schema, ensuring the accuracy and consistency of data stored in the database.
