Where can I use the HarperDB ADO.NET Provider?

ADO.NET Access to HarperDB

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 HarperDB

The HarperDB ADO.NET Provider offers the most natural way to access HarperDB data from any .NET application. Simply use HarperDB Data Provider objects to connect and access data just as you would access any traditional database. You will be able to use the HarperDB 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 HarperDB 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 HarperDB Data Provider has the same ADO.NET architecture as the native .NET data providers for SQL Server and OLEDB, including: HarperDBConnection, HarperDBCommand, HarperDBDataAdapter, HarperDBDataReader, HarperDBDataSource, HarperDBParameter, etc. Because of this you can now access HarperDB data in an easy, familiar way.

For example:

using (HarperDBConnection conn = new HarperDBConnection("...")) {
	string select = "SELECT * FROM HarperDB";
	HarperDBCommand cmd = new HarperDBCommand(select, conn);
	HarperDBDataAdapter adapter = new HarperDBDataAdapter(cmd);
	using (adapter) {
		DataTable table = new DataTable();
		adapter.Fill(table);		
		...
	}
}

More Than Read-Only: Full Update/CRUD Support

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

using (HarperDBConnection connection = new HarperDBConnection(connectionString)) {
	HarperDBDataAdapter dataAdapter = new HarperDBDataAdapter(
	"SELECT Id, Where FROM HarperDB", connection);
  
	dataAdapter.UpdateCommand = new HarperDBCommand(
		"UPDATE HarperDB SET Where = @Where " +
		"WHERE Id = @ID", connection);

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

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

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

	dataAdapter.Update(HarperDBTable);
}

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 HarperDB solves these issues by supporting powerful smart caching technology that can greatly improve the performance and dramatically reduce application bottlenecks.

Smart Caching

Smart caching is a configurable option that works by storing queried data into a local database. Enabling smart caching creates a persistent local cache database that contains a replica of data retrieved from the remote source. The cache database is small, lightweight, blazing-fast, and it can be shared by multiple connections as persistent storage.

Caching with our ADO.NET Providers is highly configurable, including options for:

  • Auto Cache - Maintain an automatic local cache of data on all requests. The provider will automatically load data into the cache database each time you execute a SELECT query. Each row returned by the query will be inserted or updated as necessary into the corresponding table in the cache database.
  • Explicit Cache - Cache only on demand. Developers decide exactly what data gets stored in the cache and when it is updated. Explicit caching provides full control over the cache contents by using explicit execution of CACHE statements.
  • No Cache - All requests access only live data and no local cache file is created.

This powerful caching functionality increases application performance and allows applications to disconnect and continue limited functioning without writing code for additional local storage and/or data serialization/deserialization.

More information about ADO.NET Provider caching and best caching practices is available in the included help files.

Visual Studio Integration & Server Explorer

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

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


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

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

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

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

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

Developer Integration: Databind to HarperDB

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


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