Overview of Virtual Data Access Components

Virtual Data Access Components (VirtualDAC), previously known as VirtualTable, is a robust library designed to enhance data processing capabilities within Delphi and C++Builder environments. It supports a variety of platforms, including Windows, Linux, macOS, iOS, and Android, for both 32-bit and 64-bit architectures. VirtualDAC empowers developers to create in-memory data storage solutions, enabling the execution of complex SQL queries directly on in-memory tables. This flexibility allows for efficient data manipulation and retrieval, making it an essential tool for modern application development.

Key Features of VirtualDAC

In-Memory Data Storage
VirtualDAC allows developers to create in-memory datasets using the TVirtualTable component. This component does not rely on external data files, which enhances performance and simplifies data management during application runtime.

Advanced SQL Query Capabilities
With the TVirtualQuery component, users can execute intricate SQL queries against in-memory data sources or data from various RDBMS systems. This feature supports multiple data sources simultaneously, allowing for seamless integration of diverse datasets.

Cross-Platform Development
VirtualDAC is a cross-platform solution compatible with RAD Studio, Delphi, and C++Builder. It supports FireMonkey for developing visually appealing applications across desktop and mobile platforms, ensuring that developers can reach a wide audience without sacrificing performance.

Design-Time Editors
The library includes advanced design-time editors that facilitate the creation of TVirtualTable fields and their population with data. These tools allow developers to save configurations in DFM files or other formats for easy reuse.

Support for Non-Tabular Data
VirtualDAC excels in handling non-tabular data structures. The TVirtualDataSet component acts as a wrapper that interacts with various types of data (like arrays or objects) without storing them in memory, providing flexibility in how data is represented and manipulated.
