What are the three sub-languages that Open SQL has standardized around?

Open SQL has standardized around three sub-languages which include the Data Manipulation Language (DML). DML is a critical component that allows developers to interact with the data stored in a database by performing operations such as inserting, updating, and deleting data records. This makes it an essential part of SQL as it facilitates the manipulation of data within the database.

The other sub-languages that are commonly associated with SQL but are not included in the standardized set for Open SQL are related to different functions. While DML focuses on manipulation, Data Definition Language (DDL) is involved in defining the structure of the database through the creation and alteration of tables and schemas. Data Control Language (DCL) deals with permissions and access controls to the data, which is also a vital aspect but falls outside the realm of DML's focus. Data Evaluation Language (DEL) is not a standard term associated with SQL sub-languages, making DML the only correct and relevant sub-language in this context.
