Using multiple connection string in data config

I have multiple web applications using multiple databases using sitefinity, but now in one of my regional application I have to show content from main application. My question is
1. can we use use multiple connection string in dataconfig.config as I default connection string name is sitefinity.
2. If yes, then how we will be using the new connection string

For eg. in Dataconfig file
<add connectionString="data source=Regional;UID=myuserid;PWD=mypwd;initial catalog=SitefinityRegionalSite" providerName="System.Data.SqlClient" dbType="MsSql" name="Sitefinity"  />


<add connectionString="data
source=MainSite;UID=myuserid;PWD=mypwd;initial catalog=SitefinityMainSite"
providerName="System.Data.SqlClient" dbType="MsSql" name="SitefinityMainSite" 
/>

in user control

 using (DynamicModuleManager dynamicModuleManager = DynamicModuleManager.GetManager())
               
                    
                    Type teamManagementType = TypeResolutionService.ResolveType("Telerik.Sitefinity.DynamicTypes.Model.TeamManagementFinal.Manageteam");
                   
                    var myCollection = dynamicModuleManager.GetDataItems(teamManagementType).Where(i => i.Status == ContentLifecycleStatus.Live && i.Visible == true);
                    
                    
                    foreach (var dataItem in myCollection)
                   
                        ManagementTeam objMgmtTeam = new ManagementTeam();
                        membername = Convert.ToString(dataItem.GetValue("Name"));
                        if (membername.ToLower() == ceoname.ToLower())
                       
                            Telerik.Sitefinity.Model.ContentLinks.ContentLink[] lstLink = (Telerik.Sitefinity.Model.ContentLinks.ContentLink[])dataItem.GetValue("ProfileImage");
                            string imageUrl = string.Empty;
                            foreach (var data1 in lstLink)
                           
                                imageUrl = data1.ChildItemAdditionalInfo;
                           
                            if (!string.IsNullOrEmpty(imageUrl))
                           
                                profileimagesrc = imageUrl;
                                objMgmtTeam.ProfileImage = profileimagesrc;
                           
                            string designationname = Convert.ToString(dataItem.GetValue("Designation"));
                            objMgmtTeam.Name = membername;
                            objMgmtTeam.Designation = designationname;
                            MgmtTeam.Add(objMgmtTeam);
                       
                   
               

Telerik.Sitefinity.DynamicTypes.Model.TeamManagementFinal.Manageteam name is same for both main site and regional  site but now I want to show on a regional site page the content of main site.
Please tell how to bind data in Telerik.Sitefinity.DynamicTypes.Model.TeamManagementFinal.Manageteam from Main site to regional site page control with deiifernt connection string that is specified in dataconfig file.

Hope I am clear with my question. Pls help me in lil hurry..

The simplest method to communicate data between the sites would be to use Sitefinity's RESTful WCF Services.
How to work with the services.
With the service you can query data from any Object type in Sitefinity including custom modules.   I don't believe having multiple connections strings will be your answer.
