Vce Salesforce-Data-Cloud Questions Latest

To create a data graph based on several Data Lake Objects (DLOs) , the consultant should map the DLOs to Data Model Objects (DMOs) and use these in the data graph. Here’s why:

Understanding Data Graphs

A data graph in Salesforce Data Cloud represents relationships between entities (e.g., customers, accounts, orders) and their attributes.

It is built using Data Model Objects (DMOs) , which provide a standardized structure for unified profiles and related data.

Why Map DLOs to DMOs?

Role of DLOs and DMOs :

DLOs are raw data sources ingested into Data Cloud.

DMOs are standardized objects used for identity resolution and unified profiles.

Mapping DLOs to DMOs ensures that raw data is transformed into a structured format suitable for data graphs.

Building the Data Graph :

Once the DLOs are mapped to DMOs, the consultant can use the DMOs to define relationships and build the data graph.

This approach ensures consistency and alignment with the unified data model.

Other Options Are Less Suitable :

A. Use a data action to update the data graph with the DLO data : Data actions are used for triggering workflows, not for building data graphs.

C. Map the DLOs directly to a data graph : DLOs cannot be directly mapped to a data graph; they must first be transformed into DMOs.

D. Batch transform the DLOs to multiple DMOs and activate these with the data graph : This is overly complex and unnecessary when mapping DLOs to DMOs suffices.

Steps to Create the Data Graph

Step 1: Map DLOs to DMOs

Navigate to Data Cloud > Data Streams and map the relevant fields from the DLOs to the corresponding DMOs.

Step 2: Define Relationships

Use the Data Model tab to define relationships between DMOs (e.g., linking Individuals to Accounts).

Step 3: Build the Data Graph

Use the mapped DMOs to create the data graph, defining nodes (entities) and edges (relationships).

Step 4: Validate the Graph

Test the data graph to ensure it accurately represents the desired relationships and data flow.

Conclusion

The consultant should map the DLOs to DMOs and use these in the data graph to ensure a structured and consistent approach to building relationships between entities.

A calculated insight is a multidimensional metric that is defined and calculated from data using SQL expressions. A calculated insight can include dimensions and measures. Dimensions are the fields that are used to group or filter the data, such as customer ID, product category, or region. Measures are the fields that are used to perform calculations or aggregations, such as revenue, quantity, or average order value. A calculated insight can be modified by editing the SQL expression or changing the data space. However, the consultant needs to be aware of the following limitations and considerations when modifying a calculated insight12:

Existing dimensions cannot be removed. If a dimension is removed from the SQL expression, the calculated insight will fail to run and display an error message. This is because the dimension is used to create the primary key for the calculated insight object, and removing it will cause a conflict with the existing data. Therefore, the correct answer is B.

New dimensions can be added. If a dimension is added to the SQL expression, the calculated insight will run and create a new field for the dimension in the calculated insight object. However, the consultant should be careful not to add too many dimensions, as this can affect the performance and usability of the calculated insight.

Existing measures can be removed. If a measure is removed from the SQL expression, the calculated insight will run and delete the field for the measure from the calculated insight object. However, the consultant should be aware that removing a measure can affect the existing segments or activations that use the calculated insight.

New measures can be added. If a measure is added to the SQL expression, the calculated insight will run and create a new field for the measure in the calculated insight object. However, the consultant should be careful not to add too many measures, as this can affect the performance and usability of the calculated insight. References: Calculated Insights, Calculated Insights in a Data Space.

Identity resolution is the process of linking data from different sources into a unified profile of a customer or an individual. Identity resolution uses matching rules to compare the attributes of different records and determine if they belong to the same person. Matching rules can be based on exact or fuzzy matching of various attributes, such as name, email, phone, address, or custom identifiers. A healthcare client who wants to use identity resolution, but does not want to risk unifying profiles that may share certain personally identifying information (PII), such as name or email, should use a matching rule criteria that is based on a unique and reliable identifier that is specific to the healthcare domain. One such identifier is the patient ID, which is a unique number assigned to each patient by a healthcare provider or system. By using the party identification on patient ID as a matching rule criteria, the healthcare client can ensure that only records that have the same patient ID are matched and unified, and avoid false positives or false negatives that may occur due to common or similar names or emails. The party identification on patient ID is also a secure and compliant way of handling sensitive healthcare data, as it does not expose or share any PII that may be subject to data protection regulations or standards. References: Configure Identity Resolution Rulesets, A framework of identity resolution: evaluating identity attributes and methods

 The field type Text should be chosen to ensure that leading zeros in the purchase order number are preserved. This is because text fields store alphanumeric characters as strings, and do not remove any leading or trailing characters. On the other hand, number, decimal, and serial fields store numeric values as numbers, and automatically remove any leading zeros when displaying or exporting the data123. Therefore, text fields are more suitable for storing data that needs to retain its original format, such as purchase order numbers, zip codes, phone numbers, etc. References:
