What Is The Difference Between A Soap Api And A Rest Api When We Can Use A Rest Api And When We Can Use A Soap Api

Salesforce developer interview questions and answers || 2022 || Part 1 || APEX

SOAP APIs use WSDL files to make objects and database access available to Salesforce. REST can be JSON- or XML-based, while SOAP is only XML-based. REST is most often used by mobile apps, while SOAP is used to connect with legacy systems. For example, if we want to connect to SAP using Salesforce, then SAP will provide a WSDL file to connect to their database. We can use REST when a third-party system wants to extract data from or insert data into a Salesforce database.

A batch class is an asynchronous method, so when the batch class runs, each execution method is processed in a separate thread. Now if we have mentioned one list globally to update all of the processed records in a finish method, then we will need to make this batch class stateful to retain the values of global variables. Otherwise, each thread will have its own separate copy of all global variables, so none of them will add to the list used by the main threads finish method.

Explain Javascript Remoting For Apex Controllers

Use javascript remoting in VisualForce to call methods in apex controllers from javascript.

Javascript remoting has 3 parts.

  • The remote method invocation you add to the VisualForce page, written in javascript.
  • The remote method definition in your Apex controller class.
  • This method definition is written in apex, but there are few differences from normal action methods.
  • The response handles callback function you add to or include in your VF page, written in javascript.

  • What is the page layout in Salesforce?Answer: Page layouts control the layout and organization of buttons, fields, related lists on object record pages, and custom links. Use them to customize the content of record pages visible to your users. Page layout determines which fields are visible, read-only, and required.
  • Can we have multiple page layouts defined for the same record type?Answer: Yes, we can every user sees a particular layout depending on record type and profile combination.
  • What are compact layouts?Answer: Compact layout is the one shown in the highlight panel when we open any record. We can add only ten fields in the compact layout.
  • Have you seen the master record type on an object? What do you understand about it?Answer: Yes, an object has no custom record types defined. The admin can see a master record type which is just a placeholder, for example, while assigning page layouts, etc.Note: Master record type does not have record type id associated with it. Moreover, once a custom record type is defined, the master record type is no more available.
  • What is the search layout, and how do we see it?Answer: Search layout is the search results fields displayed on the screen after searching any record in global search in Salesforce. We can create different search layouts for other profiles. Moreover, we can only add ten fields in search layouts.

    What Is The Use Of @future Annotation

    Future annotations are used to identify and execute methods asynchronously. If the method is annotated with @future, then it will be executed only when Salesforce has the available resources.

    For example, you can use it while making an asynchronous web service callout to an external service. Whereas without using the annotation, the web service callout is made from the same thread that is executing the Apex code, and no additional processing will occur until that callout is complete .

    What Data Types Can We Use Within Lightning Components

    Within Aura components we can use any of the basic data types, e.g. String, Boolean, Date, Object etc and arrays of those datatypes. We can also define Aura attributes to hold SObjects and move advanced datatypes such as functions, Apex defined datatypes and we can define an attribute which can store other components.

    In LWC, things are a lot more straightforward, since we do not need to define data types on our attributes. This means that an attribute of an LWC can hold any JavaScript data type for example, we can hold all the standard data types, functions, HTML Nodes, Promises and anything else that we may require.

    What Is The Use Of Writing Sharing Rules Can You Use Sharing Rules To Restrict Data Access

    Sharing rules are written to give edit access or public read onlyaccess to certain individuals in Salesforce org. A classic example is when:- only your managers or superiors need to be given extra credentials to your records in objects as compared to your peers.

    By default, all users in your organization will have organization-wide-default sharing settings of either Public Read Only or Private.To give access to more records, which users do not own, we write sharing rules.Example: Sharing rules are used to extend sharing access to users in public groups or roles. Hence, sharing rules are not as strict as organization-wide default settings. They allow greater access for those users.

    As far as the second part of the question is concerned, the answer is no. We cannot use sharing rules to restrict data access. It is only used for allowing greater access to records.

    How Can We Manage Our Events To Improve The User Experience

    In situations where an event can be frequently fired based on a user interaction, its important we handle those events in a specific way so as to not cause a detrimental impact to the users experience. A good example for this is a search bar which filters a list when a user types into it, if we were handling the onchange event, we would end up filtering after every keypress and this would cause the search to appear sluggish to the user. Instead what we want to do is set a timeout after every keypress, if the user continues to type within a small time frame , we simply cancel the previous timeout and start a new one. Now we only take the performance hit when we know the user has done something valid and the filtering appears smooth. This technique is called debouncing.

    What Are Validation Rules In Salesforce

    • Validation rules in Salesforce consist of a formula or expressions that evaluate the data in one or more fields in a record to meet the standards you specify before the user can save the record. It returns a True or False value based on the evaluation of the data. Validation rules are responsible for displaying an error message to the user when the condition is True due to an invalid value.
    • Validation rules are helpful in enforcing integrity constraints against the data. Here we give conditions in the formula editor. If one validation rule fails, Salesforce proceeds to check another validation rule held within the field or record and shows an appropriate error message at that particular field or above the record.
    • You are allowed to create validation rules for fields, objects, campaign members, or case milestones. For example, we can create a validation rule that fires when a user tries to save an account with the incorrect length for the account number.
