吸取platform app builder学习笔记的教训,在简书没有修改对于收费文章的准入门槛之前,直接用英语做复习笔记,提高备考效率。部分个人心得可能会用中文。


 Describe the considerations when developing in a multi-tenant environment.

 Describe how the Salesforce platform features map to the MVC pattern.

 Describe the capabilities of the core CRM objects in the Salesforce schema.

 Identify the common scenarios for extending an application's capabilities using the AppExchange.

 Identify common use cases for declarative customization of the Lightning Platform, and customization and features of the Heroku platform.


 Given a set of requirements, determine the appropriate data model.

 Describe the capabilities of the various relationship types and the implications of each on record access, user interface (UI), and object-oriented programming.

 Describe the impact of schema design and modifications on Apex Development.

 Describe how to visualize and create entity relationships.

 Describe the options for and considerations when importing and exporting data into development environments.


 Describe how to programmatically access and utilize the object schema.

1. Access sObject and field describe information

a. token (lightweight, serializable, validated at compile time, describes SObject or field), Schema.describeSObjects() - describe one or more SObject, Schema.DescribeSObjectResult - not serializable, and are validated at runtime, describes SObject or field

b. Use the Schema getGlobalDescribe method to return a map that represents the relationship between all sObject names (keys) to sObject tokens (values). For example:  Map<String, Schema.SObjectField> fieldMap = Schema.SObjectType.Account.fields.getMap();

2. Access Salesforce app information

Each app corresponds to a collection of tabs. Describe information for an app includes the app’s label, namespace, and tabs. Describe information for a tab includes the sObject associated with the tab, tab icons and colors.

List<Schema.DescribeTabSetResult> tabSetDesc = Schema.describeTabs();

3. Write dynamic SOQL queries, dynamic SOSL queries and dynamic DML

4. Understanding Apex Describe Information

5. Using Field Tokens

6. Understanding Describe Information Permissions

7. Describing sObjects Using Schema Method

8. Describing Tabs Using Schema Methods

9. Accessing All sObjects

10. Accessing All Data Categories Associated with an sObject

11. Dynamic SOQL

12.Dynamic SOSL

13. Dynamic DML
