Data Access Components for MySQL 5.80

Data Access Components for MySQL 5.80 (MyDAC) offers you an all-in-one and useful VCL/VCL.NET/CLX component library for fast direct access to MySQL from Delphi, C++Builder, and Kylix. MyDAC is heavily performance- and stress-tested to provide the fastest available native connectivity to MySQL. MyDAC features full support for all MySQL data types and features, including support for locking, SET and ENUM types.

The MyDAC library 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 for access to MySQL.

Advantages of MyDAC Technology

MyDAC is a direct connectivity database wrapper built specifically for the MySQL server. MyDAC offers wide coverage of the MySQL feature set, supports both client and direct connection modes, and emphasizes optimized data access strategies.

1. Wide Coverage of MySQL Features

• By providing access to the most advanced database functionality, MyDAC allows developers to harness the full capabilities of the MySQL server and optimize their database applications. MyDAC features complete support of row-level locking, HANDLER statements, and MySQL administration tasks.

2. Native Connection Options

• MyDAC offers two connection modes to MySQL: direct connection over the network in Direct mode and connection through the standard MySQL Client in Client mode. MyDAC-based database applications are easy to deploy, do not require installation of other data provider layers (such as BDE), and tend to be faster than those that use standard data connectivity solutions.

3. Optimized Code

• The goal of MyDAC is to enable developers to write efficient and flexible database applications. The MyDAC library is implemented using advanced data access algorithms and optimization techniques. Classes and components undergo comprehensive performance tests and are designed to help you write high-performance, lightweight data access layers.

4. Compatibility with Standard Data Access Components

• The MyDAC interface retains compatibility with standard VCL data access components, like BDE. Existing BDE-based applications can be easily migrated to MyDAC and enhanced to take advantage of MySQL-specific features. Project migration can be automated with the BDE Migration Wizard.

How Does MyDAC Work?

MyDAC allows you to connect to MySQL in two ways: in Direct mode or in Client mode.

In Direct mode, MyDAC connects to MySQL directly without using MySQL client software. In Client mode, MyDAC connects to MySQL through the MySQL client library. The MySQL client library is supplied with the MySQL server.

In comparison, the Borland Database Engine (BDE) uses several layers to access MySQL, and requires additional data access software to be installed on client machines.

Using MyDAC in Client mode allows your application to avoid using BDE and ODBC.

Using MyDAC in Direct mode provides the optimal transfer route.
