Getting Started With Actian Zen and BtrievePython

Welcome to the world of Actian Zen, a versatile and powerful edge data management solution designed to help you build low-latency embedded apps. This is Part 1 of the quickstart blog series that focuses on helping embedded app developers get started with Actian Zen. In this blog, we’ll explore how to leverage BtrievePython to run Btrieve2 Python applications, using the Zen 16.0 Enterprise/Server Database Engine.

But before we dive in, let’s do a quick introduction.

What is Btrieve?

Actian Zen Btrieve interface is a high-performance, low-level, record-oriented database management system (DBMS) developed by Pervasive Software, now part of Actian Corporation. It provides efficient and reliable data storage and retrieval by focusing on record-level operations rather than complex queries. Btrieve is known for its speed, flexibility, and robustness, making it a popular choice for applications that require high-speed data access and transaction processing.

What is BtrievePython?

BtrievePython is a modern Python interface for interacting with Actian Zen databases. It allows developers to leverage the powerful features of Btrieve within Python applications, providing an easy-to-use and efficient way to manage Btrieve records. By integrating Btrieve with Python, BtrievePython enables developers to build high-performance, data-driven applications using Python’s extensive ecosystem and Btrieve’s reliable data-handling capabilities.

This comprehensive guide will walk you through the setup on both Microsoft Server 2019 and Ubuntu V20, ensuring you have all the tools you need for success.

Getting Started With Actian Zen

Actian Zen offers a range of data access solutions compatible with various operating systems, including Android, iOS, Linux, Raspbian, and Windows (including IoT and Nano Server). For this demonstration, we’ll focus on Microsoft Server 2019, though the process is similar across different platforms.

Before we dive into the setup, ensure you’ve downloaded and installed the Zen 16.0 Enterprise/Server Database Engine for Windows or Linux on Ubuntu. Detailed installation instructions can be found on Actian’s Academy channel.

Setting Up Your Environment

Installing Python and BtrievePython on Windows:

• • • Download and Install Python: Visit Python’s official website and download the latest version (we’re using Python v3.12).
    • Open Command Prompt as Administrator: Ensure you have admin rights to proceed with the installation.
    • Install BtrievePython: Execute pip install btrievePython. Note that this step requires an installed ZEN 16.0 client or Engine. If the BtrievePython installation fails, ensure you have Microsoft Visual C++ 14.0 or greater by downloading the Visual C++ Build Tools.
    • Verify Installation: Run pip list to check if BtrievePython is listed.
    • Run a Btrieve2 Python Sample: Download the sample program from the Actian documentation and run it using python btr2sample.py 9 from an admin command prompt.

Installing Python and BtrievePython on Linux (Ubuntu):

• • • Install PIP: Use sudo apt install python3-pip to get PIP, the Python package installer.
    • Open a terminal window as a non-“root” user and export PATH=$PATH:/usr/local/actianzen/bin
    • Install BtrievePython: Execute sudo pip install btrievePython, ensuring a ZEN 16.0 client or Engine is present.
    • Verify Installation: Run pip show btrievePython to confirm the installation.
    • Run a Btrieve2 Python Sample: After downloading the sample from the Actian documentation, run the sample with python3 btr2sample.py 9.
