Intro
To support enterprise business, The FreeForm forms engine must be open outside the template and data access interfaces, although also based on XML, We are not the same sa some commercial products, such as InfoPath, using InfoPath make form, then you must use the Office InfoPath at client side,at the server must use SharePoint, InfoPath XML data is also difficult to apply to an external program, not to mention the template XML file, which is really a closed environment.
The FreeForm template and data are open to external access interface, now offers three ways:
1, WCF + database, you can choose SQL Server, Oracle, My SQL or ACCESS ...
2, the client side local database storage, we have created a Silverlight client database, no server side database environment needs for the user;
3, XML storage, this is no Namespace in XML, external third-party programs to access very convenient.
Client side local database storage
FreeForm have a local object database, hosted at the client Silverlight, without requiring the user to install any database system,you can also access the form template and form data,without server database environment.

WCF + database mode
First, establish a database to SQL Server as an example:
Template table, the form template definition stored here.
Form data database table, where the stored form data
We can see TempateXml and DataXml is an XML type.
Create table script as follows:
USE [FreeFormDB]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[Template](
[Guid] [nvarchar](36) NULL,
[TemplateName] [nvarchar](50) NOT NULL,
[TemplateXml] [xml] NULL,
[Type] [nvarchar](10) NULL,
[Version] [nvarchar](10) NULL,
[UpdatedDateTime] [datetime] NULL
) ON [PRIMARY]
GO
CREATE TABLE [dbo].[FormData](
[InstanceID] [nvarchar](36) NULL,
[TemplateID] [nvarchar](36) NULL,
[TemplateName] [nvarchar](50) NULL,
[DataXml] [xml] NULL,
[UpdatedDateTime] [datetime] NULL
) ON [PRIMARY]
GO
Then, the client configuration file, you must first configure the server match the certificate with the code, so that only authenticated users can access the WCF + FreeForm database interface.
