Difference between SOAP and Restful Webservice?

* REST and SOAP are the two web service frameworks available on the Force.com platform. 

* The SOAP API uses authentication with username and password, and communicates using XML messages. There are different API's to work with the Enterprise, Partner, Bulk, Metadata etc. 

*The REST API uses HTTP to authenticate, it uses a token authentication and can use OATH to authenticate, it communicates using JSON messages. 

*REST API is generally lighter weight than the SOAP API, works well with mobile applications especially.

how to lock a record?

To lock a set of sObject records in Apex, embed the keywords FOR UPDATE after any inline SOQL statement

To display all the fields of sObject using Apex & VF?

<apex:page showHeader="false" Controller="FieldsClass">
        <apex:DataTable value="{!data}" var="d">
             <apex:column headerValue="Field Name">
                 {!d}
             </apex:column>         
         </apex:DataTable>
</apex:page>
*******************************
public class  FieldsClass {

     public map<string,Schema.SObjectField> data {get;set;}
  
     public  FieldsClass (){
         data = Schema.SObjectType.Book__c.fields.getMap();
        }

public class coun {

    public Boolean hide = false;

    public Boolean hide1 = false;

    public Boolean hide2 = false;

    

    public void setMhide(Boolean b) {

    this.hide = b;

    }

    

    public Boolean getMhide() {

    return this.hide;

    }//Passing input dynamically through another method

    

    

    public Boolean getM1hide() {

        return this.hide2;

    }

    

    public void setM1hide(Boolean b) {

      this.hide2 = b;  

    }

    

    

    public Boolean getM2hide() {

        return this.hide1;

    }

    

    public void setM2hide(Boolean b) {

        this.hide1 = b;

    }

    

    

    public PageReference india() {
        setMhide(true);
        setM2hide(false);
        setM1hide(false);     
        return null;
    }//displaying only india information and hiding other information

    

     public PageReference us() {

        setM1hide(true);

        setM2hide(false);

        setMhide(false);

        return null;

    }

    

    public PageReference uk() {
