Here's from Yang's Net Zone:

using Microsoft.Practices.EnterpriseLibrary.Data;
using Microsoft.Practices.EnterpriseLibrary.Configuration;
using Microsoft.Practices.EnterpriseLibrary.Data.Configuration;

DatabaseSettings settings = new DatabaseSettings();

// This maps to  element in data config file
DatabaseTypeData type = new DatabaseTypeData("Sql Server", "Microsoft.Practices.EnterpriseLibrary.Data.Sql.SqlDatabase, Microsoft.Practices.EnterpriseLibrary.Data, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null");
settings.DatabaseTypes.Add(type);

// This maps to  element in data config file
ConnectionStringData connectionString = new ConnectionStringData("localhost.EntLibQuickStarts");

// Followings map to  elements in data config file
ParameterData param = new ParameterData("server", "localhost");
connectionString.Parameters.Add(param);

param = new ParameterData("database", "EntLibQuickStarts");
connectionString.Parameters.Add(param);

param = new ParameterData("integrated security", "true");
connectionString.Parameters.Add(param);

settings.ConnectionStrings.Add(connectionString);

// Too bad compiler gets confused InstanceData with System.Diagnostics.InstanceData.  It maps to  element in data config file
Microsoft.Practices.EnterpriseLibrary.Data.Configuration.InstanceData instance = new    Microsoft.Practices.EnterpriseLibrary.Data.Configuration.InstanceData("localhost", "Sql Server", "localhost.EntLibQuickStarts");
settings.Instances.Add(instance);

ConfigurationDictionary configurations = new ConfigurationDictionary();

// This is how to tie DatabaseSettings with ConfigurationDictionary. It maps to  element in App.config file    configurations.Add("dataConfiguration", settings);
ConfigurationContext context = ConfigurationManager.CreateContext(configurations);

Database database = new DatabaseProviderFactory(context).CreateDatabase("localhost");
