What language can be used to define and manipulate data in Oracle Autonomous Database?

SQL (Structured Query Language) is the correct choice for defining and manipulating data in Oracle Autonomous Database. SQL is a standard language specifically designed for managing and querying relational databases. It allows users to perform a variety of operations including inserting, updating, deleting, and retrieving data.

In the context of Oracle Autonomous Database, SQL is not only fundamental for interacting with the database but also serves as the primary means for creating database objects like tables and schemas. Oracle Database utilizes an enhanced version of SQL that offers additional features and optimizations unique to its platform, making it highly effective for database operations in an autonomous environment.

Other programming languages like Java, XML, and Python can interact with Oracle databases and may be used for different purposes such as application development or data interchange, but they do not serve as the primary language for defining and manipulating data within the database itself. Java can be used for stored procedures and backend applications, XML is a markup language suited for data representation, and Python can facilitate API interactions or data analysis tasks, but they do not replace SQL's core role in direct database management.
