Standard ADO.NET Access to Couchbase

The Couchbase ADO.NET Provider offers the most natural way to access Couchbase data from any .NET application. Simply use Couchbase Data Provider objects to connect and access data just as you would access any traditional database. You will be able to use the Couchbase Data Provider through Visual Studio Server Explorer, in code through familiar classes, and in data controls like DataGridView, GridView, DataSet, etc.

The CData ADO.NET Provider for Couchbase hides the complexity of accessing data and provides additional powerful security features, smart caching, batching, socket management, and more.

Working with DataAdapters, DataSets, DataTables, etc.

The Couchbase Data Provider has the same ADO.NET architecture as the native .NET data providers for SQL Server and OLEDB, including: CouchbaseConnection, CouchbaseCommand, CouchbaseDataAdapter, CouchbaseDataReader, CouchbaseDataSource, CouchbaseParameter, etc. Because of this you can now access Couchbase data in an easy, familiar way.

For example:

using (CouchbaseConnection conn = new CouchbaseConnection("...")) {
	string select = "SELECT * FROM Documents";
	CouchbaseCommand cmd = new CouchbaseCommand(select, conn);
	CouchbaseDataAdapter adapter = new CouchbaseDataAdapter(cmd);
	using (adapter) {
		DataTable table = new DataTable();
		adapter.Fill(table);		
		...
	}
}

More Than Read-Only: Full Update/CRUD Support

Couchbase Data Provider goes beyond read-only functionality to deliver full support for Create, Read, Update, and Delete operations (CRUD). Your end-users can interact with the data presented by the Couchbase Data Provider as easily as interacting with a database table. 

using (CouchbaseConnection connection = new CouchbaseConnection(connectionString)) {
	CouchbaseDataAdapter dataAdapter = new CouchbaseDataAdapter(
	"SELECT Id, Where FROM Documents", connection);
  
	dataAdapter.UpdateCommand = new CouchbaseCommand(
		"UPDATE Documents SET Where = @Where " +
		"WHERE Id = @ID", connection);

	dataAdapter.UpdateCommand.Parameters.AddWithValue("@Where", "Where");
	dataAdapter.UpdateCommand.Parameters.AddWithValue("@Id", "80000173-1387137645");

	DataTable DocumentsTable = new DataTable();
	dataAdapter.Fill(DocumentsTable);

	DataRow firstrow = DocumentsTable.Rows[0];
	firstrow["Where"] = "New Location";

	dataAdapter.Update(DocumentsTable);
}

ADO.NET Provider Performance

With traditional approaches to remote access, performance bottlenecks can spell disaster for applications. Regardless if an application is created for internal use, a commercial project, web, or mobile application, slow performance can rapidly lead to project failure. Accessing data from any remote source has the potential to create these problems. Common issues include:

  1. Network Connections - Slow network connections and latency issues are common in mobile applications.
  2. Service Delays - Delays due to service interruptions, resulting in server hardware or software updates.
  3. Large Data - Intentional or unintentional requests for large amounts of data.
  4. Disconnects - Complete loss of network connectivity.

The CData ADO.NET Provider for Couchbase solves many of these issues with support for replication queries that can be used to sync data to local databases, greatly improving the performance and dramatically reduce application bottlenecks.

More information about ADO.NET Provider performance capabilities are available in the included documentation.

Visual Studio Integration & Server Explorer

Working with the new Couchbase ADO.NET Provider is easy. As a fully-managed .NET Data Provider, the Couchbase Data Provider integrates seamlessly with the Visual Studio development environment as well as any .NET application.

As an ADO.NET Data Provider, Couchbase ADO.NET Provider can be used to access and explore Couchbase data directly from the Visual Studio Server Explorer.

It's easy. As a standard ADO.NET adapter, developers can connect the Server Explorer to Couchbase ADO.NET Provider just like connecting to any standard database.

  • Add a new Data Connection from the Server Explorer and select the Couchbase Data Source
  • Configure the basic connection properties to access your Couchbase account data.

Explore all of the data available! Couchbase ADO.NET Provider makes it easy to access live Couchbase data from Visual Studio.

  • After configuring the connection, explore the feeds, views, and services provided by the Couchbase Data Source.
  • These constructs return live Couchbase data that developers can work with directly from within Visual Studio!

Developer Integration: Databind to Couchbase

Connecting Web, Desktop, and Mobile .NET applications with Couchbase is just like working with SQL Server. It is even possible to integrate Couchbase ADO.NET Provider into applications without writing code.

Developers are free to access the Couchbase ADO.NET Provider in whatever way they like best. Either visually through the Visual Studio Winforms or Webforms designers, or directly through code.

  • Developers can connect the Couchbase Data Source directly to form components by configuring the object's smart tags.
  • Add a new Data Connection from the Server Explorer and select the Couchbase Data Source. Then, select the feed, view, or services you would like to connect the object to.

Done! It's just like connecting to SQL Server.

  • Once the object is bound to the data source, applications can easily interact with Couchbase data with full read/write (CRUD) support.
