Salesforce is the system of record in the Suspect and Prospect stages of the recruitment and admissions process for the university. A system of record is a system that serves as the authoritative source of data for a given entity or process. Salesforce is the system of record in the Suspect and Prospect stages, because it stores and manages information about potential students who have expressed interest or have been identified as targets by the university, such as name, email, phone, or program of interest. The Student Information System (SIS) is the system of record in the Applicant and Matriculated stages of the recruitment and admissions process for the university. The SIS is a system that stores and manages information about students who have applied or enrolled at the university, such as ID, transcripts, test scores, or financial aid. Reference:

The student number is the external ID that the consultant should recommend to match spreadsheet information with the Salesforce Contact record. The external ID is a field that uniquely identifies a record and can be used to match records from different data sources. The student number is a unique identifier for each student that can be used to match the spreadsheet information with the Contact record in Salesforce. The email address, company name, and company phone are not unique identifiers for each student and cannot be used as external IDs. Reference:

The consultant should use a custom index to resolve the issue of taking a long time to search and generate list views for the large online university's Salesforce environment that has a large volume of records and uses EDA. A custom index is a feature that allows users to create an index on a field that is not indexed by default, such as a custom field, a long text area field, or a multi-select picklist field. A custom index can help improve the performance and speed of queries and list views that use the indexed field as a filter. The consultant should identify the fields that are frequently used in searches and list views, and request Salesforce Support to create a custom index on them. MuleSoft Anypoint Platform, Data Loader error logs, and Table-Driven Trigger Management are not features that can resolve the issue of taking a long time to search and generate list views for the large online university's Salesforce environment that has a large volume of records and uses EDA.

TDTM is a framework that allows administrators to customize the behavior of Education Data Architecture (EDA) by defining triggers, classes, and custom settings2. One of the benefits of TDTM is that it controls the order in which operations execute, which can improve performance and avoid conflicts or errors2. For example, TDTM can ensure that account names are updated before affiliations are created, or that contact roles are deleted before opportunities are closed2.

A third-party app can provide a solution for managing volunteer events, such as Volunteerforce or HandsOn Connect, which are available on the AppExchange. Event Monitoring is a feature that tracks user activity and performance, not volunteer events. Process Builder is a tool that automates business processes, not event management. Reference:
