Mastering the Language of Databases: DDL, IDML, and EDML Explained

  What is Embedded Data Manipulation Language (EDML)? Embedded Data Manipulation Language (EDML) is a programming language that enables developers to incorporate data manipulation statements directly into the code of an application. It is commonly utilized in applications that require interaction with a database and the manipulation of data. EDML statements are embedded in the application code and can be executed by the DBMS upon running the application. This integration facilitates the seamless manipulation of data between the application and the database, without requiring the use of an external tool or interface. Some examples of EDML include embedded SQL, which allows developers to write SQL statements within their application code, and JDBC, a standard API for connecting Java applications to databases and executing SQL statements. To put it simply, EDML makes it possible to incorporate data manipulation statements directly into application code, facilitating effortless in...

  What is Interactive Data Manipulation Language (IDML)? Interactive Data Manipulation Language (IDML) is a programming language utilized for manipulating data in a database. Its primary feature is its real-time interactive interface, enabling users to execute operations such as inserting, updating, and deleting data.  IDML was designed to provide a user-friendly interface for database interaction, which allows even non-technical users to manipulate data without extensive knowledge of underlying SQL commands.  Additionally, IDML features assistive functionalities like auto-complete and syntax highlighting, enhancing the accuracy and efficiency of queries. Tools such as SQL Server Management Studio, Oracle SQL Developer, and MySQL Workbench exemplify IDML, providing users with a graphical interface for interacting with databases and performing data operations. In essence, IDML streamlines data manipulation for non-technical users, making it more accessible and convenient.

  What is Data Definition Language (DDL)? DDL is a programming language that plays a vital role in managing the structure of a database. Its main function is to create, modify and delete database objects like tables, indexes, and views. Using DDL statements, users can define the database schema by specifying the data types, constraints, and relationships between the objects. Some common DDL statements include CREATE, ALTER, and DROP statements. CREATE is used to create new database objects, ALTER is used to modify an existing object, and DROP is used to remove an object from the database. In essence, DDL is the go-to language for defining and maintaining a database's structure.
