Adds a new caslib to enable access to a data source. A caslib is an in-memory space to hold tables, access control lists, and data source information. Caslibs provide a way to organize in-memory tables and to manage access to data. All data is available to CAS through caslibs, and all operations in CAS that use tables are performed with caslibs.
La acción `alterTable` del conjunto de acciones `table` en SAS Viya permite modificar los metadatos de una tabla en memoria de CAS. Es una herramienta fundamental para la gestión de datos, ya que permite renombrar tablas, cambiar etiquetas y formatos de columnas, eliminar columnas y reordenarlas sin necesidad de recrear la tabla. Esto es especialmente útil para limpiar y preparar datos antes del análisis.
The `attribute` action manages extended attributes for in-memory tables in CAS. Extended attributes are user-defined metadata, stored as key-value pairs, that can be associated with a table or specific columns within a table. This action allows for adding, updating, dropping, and exporting these attributes, providing a flexible way to enrich data with additional context or information without altering the data itself.
