In this article, we will review some of the features and benefits of using LiteDAC v3.0.2 Full Source for Delphi, which was released on February 23, 2023. We will also show you how to install and use LiteDAC in your Delphi projects.

Features and Benefits of LiteDAC v3.0.2 Full Source for Delphi

LiteDAC v3.0.2 Full Source for Delphi offers the following features and benefits:

• Direct Mode: LiteDAC provides two ways of connection to SQLite from Delphi and other IDEs. One of them is common connection by means of the native SQLite client library. The second is a unique possibility of direct access using static linking of the client library in an application. This way, you can link SQLite statically to avoid any library dependencies and enjoy the highest performance and unlimited possibilities when working with SQLite.

• SQLite Encryption: To protect your data from unauthorized access, LiteDAC provides a powerful and customizable SQLite Database Encryption engine. You no longer have to spend money to buy expensive SQLite client libraries with support for encryption - with Static Linking, encryption support will be automatically added to your application and the following algorithms will be able to protect your data: AES, Blowfish, TripleDES, Cast128, RC4. LiteDAC also allows you to use any third-party SQLite library with SQLite Encryption support as well.

• Cross-Platform Development: LiteDAC provides a possibility of cross-platform development using SQLite and various IDEs: RAD Studio, Delphi, C++Builder, Lazarus (and FPC) on Windows, Linux, macOS, iOS, Android, and FreeBSD for both x86 and x64 platforms. LiteDAC also provides support for the FireMonkey platform, which allows you to develop visually spectacular high-performance desktop and mobile native applications.

• Wide Coverage of SQLite Features: LiteDAC allows developers to optimize their database applications and harness the full capabilities of SQLite. LiteDAC supports such SQLite features as working with user-defined functions, database encryption, backup, foreign keys, autoincrement, read uncommitted, shared-cache mode, and more.

• EntityDAC ORM for Delphi with LINQ support: EntityDAC is an ORM for Delphi with LINQ support. It provides a framework that allows you to perform object-relational mapping of database objects to Delphi classes with full support for encapsulation, inheritance, polymorphism and other OOP features. To retrieve data from a database, LINQ is used as a database independent query engine. EntityDAC is compatible with LiteDAC and allows you to use SQLite as a backend database for your ORM applications.

How to Install and Use LiteDAC v3.0.2 Full Source for Delphi

To install LiteDAC v3.0.2 Full Source for Delphi, you need to download the trial version from [Devart website] or [ComponentSource website]. The trial version includes the full source code of LiteDAC components and demos. You can also purchase the full version with a license key from these websites.

After downloading the trial version, you need to run the setup file and follow the instructions on the screen. You can choose which IDEs you want to install LiteDAC for and which components you want to include in your installation. You can also customize the installation path and other options.

Once the installation is complete, you can open your Delphi IDE and start using LiteDAC components in your projects. You can find the LiteDAC components in the Tool Palette under the Devart LiteDAC category. You can also access the LiteDAC documentation and demos from the Start menu or the installation folder.

To use LiteDAC components in your projects, you need to add the LiteDAC unit to the uses clause of your unit. For example, if you want to use the TLiteConnection component, you need to add LiteConnection to the uses clause. Then you can drag and drop the TLiteConnection component from the Tool Palette to your form or data module and set its properties in the Object Inspector. You can also create and configure LiteDAC components at runtime using code.

Here is a simple example of how to use LiteDAC components to connect to a SQLite database and execute a SQL query:

uses LiteConnection, LiteQuery; var LiteConn: TLiteConnection; LiteQuery: TLiteQuery; begin // Create and configure a connection object LiteConn := TLiteConnection.Create(nil); try // Set the database file name LiteConn.Database := 'C:\MyDatabase.db'; // Set the encryption algorithm and password (optional) LiteConn.EncryptionAlgorithm := eaAES; LiteConn.EncryptionPassword := 'mypassword'; // Open the connection LiteConn.Open; // Create and configure a query object LiteQuery := TLiteQuery.Create(nil); try // Assign the connection object LiteQuery.Connection := LiteConn; // Set the SQL statement LiteQuery.SQL.Text := 'SELECT * FROM Customers'; // Open the query LiteQuery.Open; // Process the query results while not LiteQuery.Eof do begin // Do something with the current record ShowMessage(LiteQuery.FieldByName('Name').AsString); // Move to the next record LiteQuery.Next; end; finally // Free the query object LiteQuery.Free; end; finally // Free the connection object LiteConn.Free; end; end;

For more information and examples on how to use LiteDAC components, you can refer to the [LiteDAC documentation] and [LiteDAC demos].
