Fields in PWR Apps represent what the columns represent in relational databases. It can store data values that are required for a particular object in a record. Fields can store different types of data.
There are 3 types of fields:
(A) Standard Fields
(B) Audit Fields
(C) Custom Fields
Standard Field:
Name:
Name is a standard field in an object this gets created at the time of the creation of the object.
Tags:
Using this field the user can give a tag to the record of an object from the list of values. Users can create new tags at run time as well.
Standard and Audit fields cannot be edited or deleted.
Audit Field:
Record Id:
A record id can help you identify a record in the database. Each record has a unique id which is known as the record id. It is system generated and cannot be edited or deleted.
Object Type:
We have a common collection (or object) for all the records created under the custom object. Object type contains the object name (custom object name) for which the particular record is created.
Instance:
This field contains the instance for which the record is created.
Owner:
Objects have an owner Id field that is a reference to the user who owns that record. Ownership is an important concept that affects the security model and has other implications throughout the system.
Created By:
This is the reference to the user who created that record.
Created On:
This field has a date and time at which the record is created.
Last Modified by:
This is the reference to the user who modified the record last time.
Last Modified On:
The last modified date refers to the last time a document or media file was modified. This information is gathered from metadata within the document or from the website's servers.
Is Deleted:
Is deleted field is used to keep the record of deleted records. If the user deletes any record from the account then with the help of the “Is Deleted” field we can keep the track of deleted records in the database.
The deleted records do not get permanently deleted from the database unless TTL (Time To Leave) field is applied.
Deleted By:
Deleted by field is a built-in (non-custom) audit field used to record which syncing user deleted a record.
Deleted On:
Deleted on is a field where date refers to the last time a document or file was deleted.
Is Test Record:
The field test record is used by the developer to maintain the test record.
Erase On:
When any of the records have been deleted from the org it gets reflected in the erase on the field. The restored limit for the erase on the field is of 30 days.
Is Published:
Once you publish an object, you can select which individual fields on that object are published. For standard objects that are published, a default set of fields is automatically published.
Is Manageable:
Is Manageable is a Boolean field of metadata object that is used to make an object is managed or
un-managed.
Custom Field:
Custom fields can be created on standard or custom objects. they may or may not be required.
The custom fields are added by the administrator or developer to meet the business requirements of your organization.
When we create a custom or standard field, we can decide what different type it should be (such as number, text, date, pick list, etc).
How to create a custom field:
From Profile, go on “Setup”
Click on “Schema” and select a “Objects” option

There are 26 data types that we can use to create a different field
