Embedded Data Manipulation Language (EDML)

Image
  Embedded Data Manipulation Language (EDML) is a type of programming language that is designed to be embedded within another programming language, such as C, Java, or Python. EDML allows developers to perform database operations within the context of their application code, without needing to switch between different programming languages or tools. EDML commands are typically embedded within the code of the host programming language, using special syntax that allows the EDML commands to be recognized and executed by a database management system (DBMS). This allows developers to work with data stored in a database directly from within their application code, without needing to use a separate tool or interface. Some common EDML commands include SELECT, INSERT, UPDATE, and DELETE, which are similar to the commands used in IDML. However, EDML commands are typically integrated within the code of the host programming language, which allows for greater flexibility and customization of t...

Interactive Data Manipulation Language (IDML)

  Interactive Data Manipulation Language (IDML) is a type of programming language used to interact with and manipulate data in a database. It is designed to allow users to retrieve, insert, update, and delete data from a database in an interactive and user-friendly manner. IDML is typically used by end-users who are not necessarily proficient in programming languages, but who need to work with data stored in a database. It is often used in conjunction with database management systems (DBMS), which provide the underlying infrastructure for storing and managing the data. IDML commands are typically entered through a command-line interface or a graphical user interface (GUI), which allows users to interact with the database by typing commands or selecting options from a menu. The language provides a set of commands that can be used to perform various operations on the data, such as retrieving data from a table, inserting new data into a table, updating existing data, and deleting data...

Data Definition Language

  Data Definition Language (DDL) is a set of SQL commands used to define and manage the structure of databases and database objects such as tables, views, indexes, and constraints. The primary function of DDL is to create, alter, and drop database objects. Here are some key aspects of Data Definition Language: CREATE: The CREATE command is used to create database objects such as tables, indexes, views, and constraints. ALTER: The ALTER command is used to modify the structure of an existing database object. DROP: The DROP command is used to delete a database object. TRUNCATE: The TRUNCATE command is used to remove all data from a table while preserving the structure of the table. RENAME: The RENAME command is used to change the name of a database object. CONSTRAINTS: DDL is used to define and enforce constraints on database objects such as tables, views, and indexes. Constraints are used to ensure data integrity and consistency. DATA TYPES: DDL is used to define the data types of co...
