Cisco Unified CCX Standard license includes the database steps library, which allows the script to access and manipulate data from external databases using SQL queries. The database steps library can be used to create, update, delete, or query records from any JDBC-compliant database, such as Microsoft SQL Server, Oracle, or MySQL. The database steps library can also be used to store session data, such as caller input or agent information, in a database table for later retrieval or reporting. The database steps library is useful for creating dynamic and personalized applications that can interact with external data sources.

The other options are incorrect because they are not included in the Cisco Unified CCX Standard license. The ICM steps library is only available with the Cisco Unified CCX Premium license, and it allows the script to integrate with the Cisco Unified Intelligent Contact Management (ICM) system for routing and reporting purposes. The email steps library is also only available with the Cisco Unified CCX Premium license, and it allows the script to send and receive email messages from customers or agents. The document steps library is available with the Cisco Unified CCX Enhanced or Premium licenses, and it allows the script to read and write documents from the local file system or a remote server using FTP or HTTP protocols. The document steps library can be used to store or retrieve data in XML, CSV, or plain text formats. References := Cisco Unified Contact Center Express Editor Step Reference Guide, Release 12.5(1) SU3, Chapter 2: Unified CCX Editor Step Reference, Database Steps, page 2-15.
