What is Devart UniDAC Pro?




Devart UniDAC Pro is a product of Devart Software, a company that specializes in developing database tools and native data access solutions for various technologies. Devart was founded in 1997 and has been providing high-quality products and services ever since.


Devart UniDAC Pro stands for Universal Data Access Components Professional. It is a library of components that provides direct access to multiple databases from Delphi and C++Builder including Community Edition, as well as Lazarus (and Free Pascal) on Windows, Linux, macOS, iOS, and Android for both 32-bit and 64-bit platforms.


Devart UniDAC Pro consists of the following main components:


  • UniConnection: This component allows you to establish a connection to a database server using various connection options and parameters.



  • UniQuery: This component allows you to execute SQL queries and commands on the server and retrieve data from the result sets.



  • UniTable: This component allows you to access and manipulate data from a single table or view on the server.



  • UniStoredProc: This component allows you to execute stored procedures and functions on the server and retrieve data from the output parameters and result sets.



  • UniScript: This component allows you to execute multiple SQL statements separated by delimiters on the server.



  • UniSQL: This component allows you to execute SQL statements that do not return any data, such as DDL or DML statements.



  • UniDataSource: This component links data-aware controls on the form with datasets (such as UniQuery or UniTable) that provide data.



  • UniProvider: This component is an intermediate layer between UniDAC components and specific database servers. It implements server-specific features and optimizes performance for each supported database.



  • CRBatchMove: This component allows you to perform batch data transfer between different sources and destinations, such as datasets, files, or streams.



In addition to these components, Devart UniDAC Pro also includes a set of design-time tools, such as editors, wizards, and monitors, that help you configure and manage your database connections and queries.

You can use the same UniDAC components to work with any of these databases or cloud services. You just need to specify the provider name and the connection parameters in the UniConnection component. Devart UniDAC Pro will handle the rest for you.


Server-Aware Providers




Devart UniDAC Pro is not only a universal data access solution, but also a server-aware one. This means that it can automatically choose the best way to perform operations on different database servers. For example, Devart UniDAC Pro can use native protocols and APIs to communicate with Oracle, MySQL, PostgreSQL, SQLite, InterBase, Firebird, and MongoDB servers. This ensures high performance and reliability of your database applications.


Devart UniDAC Pro can also detect the server version and capabilities and adjust its behavior accordingly. For example, Devart UniDAC Pro can use server-specific features such as auto-increment fields, identity columns, sequences, generators, returning clauses, etc. Devart UniDAC Pro can also handle server-specific data types such as XML, JSON, BLOBs, CLOBs, etc.


Devart UniDAC Pro can also optimize the execution of SQL queries and commands on different database servers. For example, Devart UniDAC Pro can use server-side cursors, array DML, batch operations, prepared statements, etc. Devart UniDAC Pro can also handle server-specific errors and exceptions and provide detailed information about them.


Cross-Platform Solution




Devart UniDAC Pro is a cross-platform solution that supports various IDEs, platforms, and architectures for developing database applications. You can use Devart UniDAC Pro with the following IDEs:



Embarcadero RAD Studio 10.2 Tokyo (Delphi and C++Builder) Lazarus 1.6.4 and Free Pascal 3.0.2 for Windows, Linux, macOS (x86) Lazarus 1.8 RC5 and Free Pascal 3.0.4 for Windows (x64)


You can also use Devart UniDAC Pro to develop applications for the following platforms:



Windows (32-bit and 64-bit) Linux (32-bit and 64-bit) macOS (32-bit and 64-bit) iOS (32-bit and 64-bit) Android (32-bit and 64-bit)


You can also use Devart UniDAC Pro to develop applications for the following architectures:



x86 (Intel Pentium or AMD Athlon and compatible) x64 (Intel Core or AMD Ryzen and compatible) x86_64 (Intel Core or AMD Ryzen and compatible) x86_64_macos (Intel Core or AMD Ryzen and compatible) arm (ARMv7 and compatible) arm64 (ARMv8 and compatible)


Devart UniDAC Pro allows you to create cross-platform applications that can run on different devices and operating systems without any code changes. You can also use the same code base to target different platforms and architectures. Devart UniDAC Pro supports the FireMonkey framework for creating cross-platform GUI applications, as well as the VCL framework for creating Windows-only applications.


Server-Independent SQL




Devart UniDAC Pro supports writing server-independent SQL queries using macros engine. Macros are placeholders that are replaced with actual values at runtime depending on the server type and version. For example, you can use the following macro to insert a record into a table with an auto-increment field:



INSERT INTO Customers (Name, Phone) VALUES (:Name, :Phone) RETURNING <AUTOINC_FIELD>


The macro <AUTOINC_FIELD> will be replaced with the appropriate expression for the server, such as IDENTITY, LAST_INSERT_ID, or GEN_ID. This way, you can write the same SQL query for different servers without worrying about the syntax differences.


Devart UniDAC Pro also supports using macros in design-time tools, such as SQL editors and query builders. You can define your own macros or use the predefined ones. You can also use macros in conjunction with server-specific SQL features, such as stored procedures, functions, triggers, etc.


EntityDAC ORM for Delphi with LINQ support




Devart UniDAC Pro integrates with EntityDAC ORM framework for Delphi. EntityDAC is an object-relational mapping (ORM) framework that allows you to work with database objects as if they were Delphi objects. You can use EntityDAC to create, read, update, and delete data from your database using Delphi classes and methods.


EntityDAC supports LINQ (Language Integrated Query) syntax for writing queries in Delphi code. LINQ is a powerful and expressive way of querying data from various sources using a common syntax. For example, you can use the following LINQ query to get the names of customers who live in New York:



var Customers: TList<TCustomer>; Customer: TCustomer; begin Customers := Context.Customers.Where(c => c.City = 'New York').ToList; for Customer in Customers do ShowMessage(Customer.Name); end;


EntityDAC also supports using LINQ in design-time tools, such as ORM model designer and LINQ debugger. You can use EntityDAC to create and edit your ORM models visually, as well as debug and execute your LINQ queries.


Access Cloud Services




Devart UniDAC Pro allows you to access data stored in various cloud services using ODBC drivers. ODBC drivers are software components that enable applications to connect to data sources using the ODBC standard. Devart provides ODBC drivers for many popular cloud services, such as Amazon Redshift, Azure SQL Database, Google BigQuery, Salesforce, etc.


You can use Devart UniDAC Pro components to work with cloud data sources using ODBC drivers. You just need to specify the ODBC provider name and the connection string in the UniConnection component. Devart UniDAC Pro will handle the rest for you.


You can also use Devart UniDAC Pro components to perform CRUD operations on cloud data sources using ODBC drivers. You can use UniQuery, UniTable, UniStoredProc, UniSQL, or CRBatchMove components to execute SQL queries and commands on cloud data sources. You can also use UniDataSource component to link data-aware controls on the form with cloud data sources.


Secure Connection




Devart UniDAC Pro can use SecureBridge components to establish a secure connection to the server using SSL, SSH, or HTTP/HTTPS protocols. SecureBridge is a library of components that provides secure network connections for your applications.


You can use SecureBridge components to protect your data from unauthorized access and tampering. You can also use SecureBridge components to bypass firewalls and proxy servers that may block your connection to the server.


You can use Devart UniDAC Pro components in conjunction with SecureBridge components to connect to your database servers securely. You just need to specify the SecureBridge provider name and the connection parameters in the UniConnection component. Devart UniDAC Pro will handle the rest for you.
