dbExpress is a database-independent layer that defines common interface to provide fast access to InterBase and Firebird from Delphi and C++Builder on Windows and Mac OS X for both 32-bit and 64-bit platforms. For these servers, dbExpress provides a driver as an independent library that implements the common dbExpress interface for processing queries and stored procedures. As data-access layer is thin and simple, dbExpress provides high performance database connectivity and is easy to deploy. You can use our driver in the same way as the one supplied by Embarcadero.
Native Connectivity to Oracle.

InterBase (and FireBird) Data Access Components (IBDAC) is a library of components that provides native connectivity to InterBase, Firebird and Yaffil from Delphi, C++Builder, Lazarus (and Free Pascal) on Windows, Mac OS X, iOS, Android, Linux, and FreeBSD for both 32-bit and 64-bit platforms. IBDAC-based applications connect to the server directly using the InterBase client. IBDAC is designed to help programmers develop faster and cleaner InterBase database applications. IBDAC is a complete replacement for standard InterBase connectivity solutions. It presents an efficient alternative to InterBase Express Components, the Borland Database Engine (BDE), and the standard dbExpress driver for access to InterBase.

MySQL Data Access Components (MyDAC) is a library of components that provides direct access to MySQL from Delphi, C++Builder, Lazarus (and Free Pascal) on Windows, Mac OS X, iOS, Android, Linux, and FreeBSD for both 32-bit and 64-bit platforms. Applications based on MyDAC can connect directly to MySQL server or work through the MySQL client library. MyDAC is designed to help programmers develop faster and cleaner MySQL database applications. MyDAC is a complete replacement for standard MySQL connectivity solutions and presents an efficient alternative to the Borland Database Engine (BDE) and standard dbExpress driver for access to MySQL.

Virtual Serial Port Driver creates virtual serial ports and connects them in pairs via virtual null modem cable. Applications on both ends of the pair will be able to exchange data in such a way, that everything written to the first port will appear in the second one and backwards.

ZylGPSReceiver is an award-winning Delphi & C++Builder component collection that communicates with a GPS receiver (Global Positioning System).
It returns latitude, longitude, altitude, speed, heading and many other useful parameters of the current position and the parameters of the satellites in view. The component is extended to calculate distances and make conversions between different measurement units. This component works with any NMEA 0183 compilant GPS receiver connected to one of the serial ports. NMEA 0183 (or NMEA for short) is a combined electrical and data specification for communication between marine electronic devices such as echo sounder, sonars, Anemometer (winds speed and direction), gyrocompass, autopilot, GPS receivers and many other types of instruments. It has been defined by, and is controlled by, the US-based National Marine Electronics Association. You can use it also with USB, IrDA and Bluetooth devices, because these devices have a driver that redirects the input from the USB, IrDA or Bluetooth port to a virtual serial port (you can check it in System/Device Manager/Ports). If your USB device is not provided with such a driver, then use a USB controller whose vendor provides a virtual serial port driver, such as FTDI or use a USB/RS-232 adapter. For Garmin receivers you have to install Spanner software.

dbExpress is a database-independent layer that defines common interface to provide fast access to SQL Server from Delphi and C++Builder on Windows for both 32-bit and 64-bit platforms. For this server, dbExpress provides a driver as an independent library that implements the common dbExpress interface for processing queries and stored procedures. As data-access layer is thin and simple, dbExpress provides high performance database connectivity and is easy to deploy. You can use our driver in the same way as the one supplied by Embarcadero. dbExpress driver for SQL Server provides access to SQL Server database. It works using high performance Microsoft OLE DB technologies. The driver requires OLE DB installed on the workstation.
