Transform and Enrich Data in Oracle Analytics Cloud

 

Data set is combination of facts and information, before representing/visualizing the Data set we need to prepare and clean it so that one can understand easily, and access enough based on privacy. Preparing and cleansing your data is an important step before visualizing a data set. For example, the set might have sensitive data such as customers’ social security numbers that you don’t want to expose. You can hide or transform all characters of the social security number column, remove columns from a data set, or extract portions of a data column to create a new column that contains the extracted data.

We have recommendations and available data preparation options in Oracle Analytics to improve data quality.

We have used spreadsheet as the data source. We have added spreadsheet files that have the XLSX extension and that are no larger than 100 MB. We do have option to create data set from comma-separated value (CSV) and text (TXT) files.

Step1: Create a Data Set as given below:

Changes done by us will be recorded in a Preparation Script on the Prepare page. A blue dot Blue dot icon indicates that the script hasn’t been applied to the data source. The changes are implemented when you select Apply Script. The changes are complete when the Apply Script progress indicator disappears.

Step2: Create a Project and Data Source:

 

In the right side of the page you will be able to see recommendations for the data, by column, in the data set. If recommendations are relevant to your data, then you can select if not then we have to do changes on data accordingly.

5. Don’t forget to Apply Script after doing every change otherwise it will not reflect.

 

Step4: Conceal Sensitive Customer Data

 

To comply with security policies for sensitive data, we can obfuscate all or a portion of the data in a column. If some users need to see the sensitive data, you can create a duplicate data set containing the sensitive data.

1. In Results, select the ccnumber column.
2. In the Recommendations list, click Obfuscate First 12 Digits of ccnumber.
3. In Results, select the ccn column. In the Recommendations list, click Obfuscate First 5 digits of ccn.

Preparation script contains the pending changes that are applied when the script is run.

Oracle Analytics automatically saves the changes in the data set.
