which of the following is true about Data Sets
-
Data Sets can be managed independently of a job using the Data Set Management Utility available through Websphere Datastage Director
-
Data Sets are operating system Files
-
Data can be reffered to by a Control File ,which by convention has the suffix .ds
-
Data Sets carry formatting information that describe the format of the files to be read or written
To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) Data Sets can be managed independently of a job using the Data Set Management Utility available through Websphere Datastage Director - This option is correct. Data Sets can be managed independently of a job using the Data Set Management Utility available through Websphere Datastage Director. This utility allows users to create, delete, modify, and view data sets without impacting the jobs that use them.
Option B) Data Sets are operating system Files - This option is correct. Data Sets in Websphere Datastage are represented as operating system files. These files are used to store and manage data within the Datastage environment.
Option C) Data can be referred to by a Control File, which by convention has the suffix .ds - This option is correct. Data Sets can be referred to by a Control File, which is a file that contains information about the data set. By convention, the Control File has the suffix .ds.
Option D) Data Sets carry formatting information that describes the format of the files to be read or written - This option is incorrect. Data Sets in Websphere Datastage do not carry formatting information. Instead, the format of the files to be read or written is defined separately and can be specified in the job design.
The correct answer is A, B, C. These options are correct because they accurately describe features and characteristics of Data Sets in Websphere Datastage.
