Both Lookup and Master detail fields are used to link a record in one object to another record in another object.
In lookup, if we delete master records, child records will not be deleted.
In master-detail, if we delete master records, child records will also be deleted.
Child record is mandatory for Master-Detail.
What is an External Id?
External Id is an id that can be given to any field in an object. An external id will be generated on the field that we mention.

Difference between Formula and Roll-up summary
Formula: is a read only field that derives a value from a formula expression that we define.
Roll-up summary: A read-only field that displays the sum, minimum, or maximum value of a field in a related list or the record count of all records listed in a related list.
Difference btw isNull and isBlank
IsNull – it supports for Number field.
IsBlank- it supports for Text field.
What is a workflow? Types of workflow and actions in workflow.
Workflow is a force platform business logic engine that allows us to automatically send email alerts, assign tasks, field updates based on rules that we define.
2 types:
Immediate actions: That executes when a record matches the criteria.
Time-dependent: When a record matches the criteria, and executes according to time triggers.
Actions:
Task : Asign a new task to user.

URL Current Page
Profile Page Reference
User Object Type
Resource Component

{
Pagereference p = new pageReference(‘http://www.google.com’);
Return p;
}
What is MVC?
The main aim of the MVC architecture is to separate the business logic and application data from the presentation data to the user.

What are triggers? Types of Triggers
Trigger is a piece of code that is executed before or after a particular field of certain type is inserted, updated or deleted.
Bulk Trigger: All triggers are bulk triggers by default, and can process multiple records at a time. You should always plan on processing more than one record at a time.
Bulk triggers can handle both single record updates and bulk operations like:
Data import
Mass actions, such as record owner changes and deletes
Recursive Apex methods and triggers that invoke bulk DML statements.
Recursive trigger:
ActionSupport: A component that adds AJAX support to another component, allowing the component to be refreshed asynchronously by the server when a particular event occurs, such as a button click or mouseover.
ActionFunction: A component that provides support for invoking controller action methods directly from JavaScript code using an AJAX request.
ActionPoller: A timer that sends an AJAX update request to the server according to a time interval that you specify.
What is Batch Apex? How can you implement Batch Apex?(Dynamic Apex)
Batch Apex gives you the ability to operate over large amounts of data by chunking the job into smaller parts, thereby keeping within the governor limits.
Using batch Apex, you can build complex, long-running processes on the Force.com platform. For example, you could build an archiving solution that runs on a nightly basis, looking for records past a certain date and adding them to an archive.
What is a Callout method? How does it invoke, how many methods available in Classes and Triggers?
It is used to invoke the External services HTTP or web services.
An Apex callout enables you to integrate your Apex with an external service by making a call to an external Web service or sending a HTTP request from an Apex script and then receiving the response. Apex provides integration with Web services that utilize SOAP and WSDL, or HTTP services (RESTful services).
What is a difference between System log and debug log?
System Log console is a separate window that displays debugging information, as well as its cumulative limits and source code. It can be considered a context-sensitive execution viewer showing the source of an operation, what triggered that operation, and what occurred afterward. Use the System Log console to view debug logs that include database events, Apex processing, workflow, and validation logic.
Debug log records database operations, system processes, and errors that occur when executing a transaction or while running unit tests. The system generates a debug log for a user every time that user executes a transaction that is included in the filter criteria.

Supports Seamless Upgrading
Supports LMA for Managing Installs
When to Use 1:1 Distribution
Extensive Modification Required 1:Many Distribution
Commerical Intent
Foresee Upgrades
Editions Supported All Editions can create Unmanaged Packages ONLY Developer Edition can create Managed Packages
Managed packages differ from unmanaged packages in many other ways. Before creating managed packages, here are a few things to consider:
You must use a Developer Edition organization to create and work with a managed package.
A Developer Edition organization can contain a single managed package and many unmanaged packages.
You must register a Namespace Prefix - A Namespace Prefix is a series of characters prefixed to your Custom Objects and Fields to prevent conflict when installed in another salesforce.com org.
When you release a managed package, meaning it is uploaded with the Managed - Released option selected, the properties of its components change to prevent developers and installers from making harmful changes. For a list of each package component type and their properties, see Properties of Managed Packages. If you do not want to offer upgrades to your package, consider keeping it unmanaged.
If you plan to release your app as a Managed Package, please read out guide on Planning the Release of Managed Packages
If you already have a Unmanaged Package and you'd like to convert it to Managed, please review the following: Converting Unmanaged Packages to Managed
Now that you understand the difference and benefits of each type of package, let's see how easy it is to make your Unmanaged package from above into a Managed Package.

You must register a Namespace Prefix - A Namespace Prefix is a series of characters prefixed to your Custom Objects and Fields to prevent conflict when installed in another salesforce.com org.
When you release a managed package, meaning it is uploaded with the Managed - Released option selected, the properties of its components change to prevent developers and installers from making harmful changes. For a list of each package component type and their properties, see Properties of Managed Packages. If you do not want to offer upgrades to your package, consider keeping it unmanaged.
If you plan to release your app as a Managed Package, please read out guide on Planning the Release of Managed Packages
If you already have a Unmanaged Package and you'd like to convert it to Managed, please review the following: Converting Unmanaged Packages to Managed
Now that you understand the difference and benefits of each type of package, let's see how easy it is to make your Unmanaged package from above into a Managed Package.
