xBase .NET Connectivity Features

  • Connect with xBase-compatible Database Engines like FoxPro & Clipper (.dbf, .ndx, .ntx, .dbt, etc).
  • Connect to live xBase data, for real-time data access with the xBase ODBC Driver
  • Full support for data aggregation and complex JOINs in SQL queries
  • Generate table schema automatically based on existing xBase data or manually for greater control of the content you need
  • Seamless integration with leading BI, reporting, and ETL tools and with custom applications via the xBase Connector.

Target Service, API

The driver connects to xBase-compatible database engines like FoxPro, Clipper, dBase, and others. Supports file formats including .dbf, .ndx, .ntx, .dbt, .fpt, .cdx files. Direct file system access to xBase database files.

Schema, Data Model

The driver automatically generates table schema based on existing xBase data files. Manual schema control available for greater customization. Supports memo fields, index files, and complex data types. The DataSource property must point to the folder containing .dbf files.

Key Objects

All tables defined in .dbf files within the specified folder. Index files (.ndx, .ntx, .cdx) for optimized data access. Memo fields stored in .dbt or .fpt files. Support for multiple xBase dialects including FoxPro, Clipper, dBase III/IV.

Operations

Full ANSI-92 SQL support on xBase data. SELECT, INSERT, UPDATE, DELETE operations. Complex JOINs between xBase tables. Data aggregation functions (SUM, AVG, MAX, MIN). Table creation and schema modification. Replication queries for syncing to other databases.

Authentication

File-based access requiring file system permissions. No built-in authentication (relies on file system security). Network access if files are on network shares. Support for read-only and read-write modes.

Standard ADO.NET Access to xBase

The xBase ADO.NET Provider offers the most natural way to access xBase data from any .NET application. Simply use xBase Data Provider objects to connect and access data just as you would access any traditional database. You will be able to use the xBase 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 xBase 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 xBase Data Provider has the same ADO.NET architecture as the native .NET data providers for SQL Server and OLEDB, including: xBaseConnection, xBaseCommand, xBaseDataAdapter, xBaseDataReader, xBaseDataSource, xBaseParameter, etc. Because of this you can now access xBase data in an easy, familiar way.

For example:

using (xBaseConnection conn = new xBaseConnection("...")) {
	string select = "SELECT * FROM FoxProTable";
	xBaseCommand cmd = new xBaseCommand(select, conn);
	xBaseDataAdapter adapter = new xBaseDataAdapter(cmd);
	using (adapter) {
		DataTable table = new DataTable();
		adapter.Fill(table);		
		...
	}
}


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

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

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

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

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

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

Developer Integration: Databind to xBase

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

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