Where can I use the Cloudant ADO.NET Provider?

ADO.NET Access to IBM Cloudant

Full-featured and consistent SQL access to any supported data source through ADO.NET

  • Fully-managed .NET

    100% fully managed ADO.NET libraries supporting .NET Standard, .NET Core 2.0, & Xamarin.

  • Developer Friendly

    Seamless integration with all versions of Visual Studio.

  • Powerful ADO.NET Features

    Including support for ADO.NET Entity Framework (EF 5 & 6), ADO.NET 2.0, LINQ to Datasets, etc.

  • Replication and Caching

    Our replication and caching commands make it easy to copy data to local and cloud data stores such as Oracle, SQL Server, Google Cloud SQL, etc. The replication commands include many features that allow for intelligent incremental updates to cached data.

  • String, Date, Numeric SQL Functions

    The driver includes a library of 50 plus functions that can manipulate column values into the desired result. Popular examples include Regex, JSON, and XML processing functions.

  • Collaborative Query Processing

    Our drivers enhance the data source's capabilities by additional client side processing, when needed, to enable analytic summaries of data such as SUM, AVG, MAX, MIN, etc.

  • Easily Customizable and Configurable

    The data model exposed by our ADO.NET Providers can easily be customized to add or remove tables/columns, change data types, etc. without requiring a new build. These customizations are supported at runtime using human-readable schema files that are easy to edit.

  • Secure Connectivity

    Includes standard Enterprise-class security features such as TLS/ SSL data encryption for all client-server communications.

Standard ADO.NET Access to Cloudant

The Cloudant ADO.NET Provider offers the most natural way to access Cloudant data from any .NET application. Simply use Cloudant Data Provider objects to connect and access data just as you would access any traditional database. You will be able to use the Cloudant 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 IBM Cloudant 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 Cloudant Data Provider has the same ADO.NET architecture as the native .NET data providers for SQL Server and OLEDB, including: CloudantConnection, CloudantCommand, CloudantDataAdapter, CloudantDataReader, CloudantDataSource, CloudantParameter, etc. Because of this you can now access Cloudant data in an easy, familiar way.

For example:

using (CloudantConnection conn = new CloudantConnection("...")) {
	string select = "SELECT * FROM CloudantDB";
	CloudantCommand cmd = new CloudantCommand(select, conn);
	CloudantDataAdapter adapter = new CloudantDataAdapter(cmd);
	using (adapter) {
		DataTable table = new DataTable();

More Than Read-Only: Full Update/CRUD Support

Cloudant 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 Cloudant Data Provider as easily as interacting with a database table.

using (CloudantConnection connection = new CloudantConnection(connectionString)) {
	CloudantDataAdapter dataAdapter = new CloudantDataAdapter(
	"SELECT Id, Where FROM CloudantDB", connection);
	dataAdapter.UpdateCommand = new CloudantCommand(
		"UPDATE CloudantDB SET Where = @Where " +
		"WHERE Id = @ID", connection);

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

	DataTable CloudantDBTable = new DataTable();

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


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

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

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

  • Add a new Data Connection from the Server Explorer and select the IBM Cloudant Data Source

  • Configure the basic connection properties to access your IBM Cloudant account data.

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

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

Developer Integration: Databind to Cloudant

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

Developers are free to access the Cloudant 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 IBM Cloudant 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 IBM Cloudant 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 IBM Cloudant data with full read/write (CRUD) support.
