Salesforce Vocabulary
Apex Transaction?
An
Apex transaction represents a set of operations that are executed as a single
unit. All DML operations in a transaction either complete successfully, or if
an error occurs in one operation, the entire transaction is rolled back and no
data is committed to the database. The boundary of a transaction can be a
trigger, a class method, an anonymous block of code, a Visualforce page, or a
custom Web service method.
Merge = delete
+ update
Upsert =
insert + update
upsert(): Creates new records and updates existing records;
uses a custom field to determine the presence of existing records. In most
cases, we recommend that you use upsert()
instead of create() to avoid creating unwanted duplicate
records (idempotent).
API objects represent
database tables that contain your organization's information.
The
term “record” describes a particular occurrence of an object. A record is analogous to a row in a database table.
Cross-object formulas
are formulas that span two or more objects by referencing merge fields from
related records
sObjects refers to any object that can be stored
in the Force.com platform database.
sObject is a generic abstract type that
corresponds to any persisted object type. The generic sObject can be cast into
a specific sObject type, such as an account or the Invoice_Statement__c custom
object.
Before
inserting a new sObject record, you must set all required fields for a
successful insertion.
The
fields of an sObject can be set either by passing them as arguments in the
constructor or after creating the sObject type by using the dot notation.
implements
keyword

static keyword

final

Salesforce
licenses are designed for users who require full
access to standard CRM and Force.com AppExchange apps. CRM apps are anything
that requires access to Standard Objects like...
- Leads
- Opportunities
- Forecasts
- Cases
- Solutions
Salesforce Platform licenses
are designed for users who only need access to custom apps, and NOT the
standard CRM functionality. Salesforce Platform users DO have access to the
"core" Salesforce Standard Objects and functionality, like...
- Accounts
- Contacts
- Reports
- Dashboards
- Documents
- Custom
Tabs
So,
if a user only needs to access custom Force.com or AppExchange apps, it's OK to
assign them a Salesforce Platform license. On the other hand, if a user needs
access to any CRM functionality (eg Sales or Service Cloud), they must be
assigned a Salesforce license.
