## What is Firebird and what are its main characteristics? Firebird is a free and open source RDBMS that was derived from InterBase, a commercial database product developed by Borland. Firebird was created in 2000 when Borland released the source code of InterBase 6.0 under an open source license. Since then, Firebird has been developed and maintained by a community of volunteers and contributors, who have added many features and improvements to the original code base.

Firebird supports the SQL standard and runs on various operating systems, such as Windows, Linux, MacOS, Solaris, HP-UX, and more. It can be used as a standalone server or as an embedded library within applications. It supports multiple architectures, such as SuperServer, Classic Server, SuperClassic Server, and Embedded Server, each with different performance and scalability characteristics.
Some of the notable features of Firebird are:
Full support for stored procedures and triggers
Referential integrity
Full ACID compliant transactions
Support for external functions
Careful writes - fast recovery, no need for transaction logs
Incremental backups
Full cursor implementation in PSQL
Third-party tools, including GUI administrative tools and replication tools
## How to install Firebird on different platforms? To install Firebird on your system, you need to download the appropriate installation kit from the official website: [22]( There are different installation kits for different platforms and architectures. For example, for Windows 32-bit systems, you can choose between an executable installer or a zip kit. For Linux systems, you can choose between RPM or tar.gz packages.
The installation process is usually straightforward and does not require much configuration. However, if you encounter any problems or have special needs, you should read the installation notes chapter in the release notes for your version of Firebird. You can find the release notes here: [25](
After installing Firebird, you can test your installation by connecting to a sample database that is included with the installation kit. The sample database is called employee.fdb and it is located in the examples\empbuild subdirectory of your Firebird installation directory. You can use any client tool that supports Firebird to connect to this database. For example, you can use isql, a command-line tool that comes with Firebird, or FlameRobin, a graphical tool that you can download from [26](
## How to create and manage databases with Firebird? To create a new database with Firebird, you need to use a client tool that can execute SQL commands. You can use isql or FlameRobin as mentioned before, or any other tool that supports Firebird. The basic syntax for creating a database is:
CREATE DATABASE 'database_name' USER 'user_name' PASSWORD 'password';
This command will create a new database file with the specified name and assign it to the specified user with the specified password. You can also specify other options, such as page size, character set, dialect, etc. For more details on the syntax and options of CREATE DATABASE, see [27](
To manage your databases with Firebird, you can use various SQL commands and statements to perform tasks such as creating tables, indexes, views, triggers, stored procedures, etc., inserting, ## What are some of the advanced features of Firebird? Firebird is not only a free and open source RDBMS, but also a powerful and versatile one. It offers many advanced features that can enhance the performance, security, and functionality of your applications. Here are some examples of these features:
Wire encryption: Firebird 3.0 and higher versions support encrypting the network traffic between the client and the server, using the Srp or Win_Sspi authentication plugins. This feature can protect your data from eavesdropping and tampering by unauthorized parties. To enable wire encryption, you need to configure some settings in firebird.conf or databases.conf files on the server side, and in firebird.msg file on the client side. For more details, see [28](
External engines: Firebird 3.0 and higher versions support plugging in external engines that can handle specific data types or tasks. For example, you can use the external engine feature to store and query JSON data, geospatial data, full-text indexes, etc. External engines are implemented as dynamic libraries that conform to a certain API. You can create your own external engines or use existing ones from third-party vendors or open source projects. For more details, see [29](
Packages: Firebird 3.0 and higher versions support packages, which are collections of related database objects, such as tables, views, procedures, functions, etc. Packages can help you organize your database schema into logical units, and provide namespace and visibility control for the objects within them. You can create, alter, or drop packages using SQL commands, and reference the objects in them using qualified names. For more details, see [30](
Global temporary tables: Firebird 2.1 and higher versions support global temporary tables (GTTs), which are tables that store data only for the duration of a transaction or a connection. GTTs can be useful for storing intermediate results, caching data, or performing complex calculations. You can create GTTs using the CREATE GLOBAL TEMPORARY TABLE command, and specify whether the data should be preserved or deleted on commit or disconnect. GTTs are not visible to other connections, and do not participate in transactions or backups. For more details, see [31](
Change views: Firebird 4.0 introduces a new feature called change views, which allows you to track changes made to a set of tables by other transactions. Change views can help you implement efficient synchronization mechanisms for distributed or mobile applications, without using triggers or timestamps. You can create change views using the CREATE CHANGE VIEW command, and specify which tables and columns you want to monitor. You can then query the change view using the SELECT ... FROM CHANGES command, and get a result set that shows the inserted, updated, or deleted rows since the last query. For more details, see [32](
## How to compare Firebird with other popular RDBMSs? Firebird is one of the many RDBMSs available in the market, each with its own strengths and weaknesses. Depending on your needs and preferences, you may find Firebird more or less suitable than other RDBMSs for your projects. Here are some criteria that you can use to compare Firebird with other popular RDBMSs:
Cost: Firebird is free and open source, which means you do not have to pay any license fees or royalties to use it in your applications. You also do not have to worry about vendor lock-in or support contracts. Other RDBMSs may have different pricing models, such as commercial licenses, subscriptions, donations, etc.
Platform support: Firebird runs on various operating systems and hardware platforms, such as Windows, Linux, MacOS, Solaris, HP-UX, etc. It also supports multiple architectures, such as SuperServer, Classic Server, and Embedded Server, each with different performance and scalability characteristics. Other RDBMSs may have different platform support and architecture options, such as cloud-based, distributed, or clustered.
Features: Firebird offers many features that can enhance the performance, security, and functionality of your applications, such as wire encryption, external engines, packages, global temporary tables, change views, etc. Other RDBMSs may have different or similar features, depending on their design and development goals.
Community: Firebird is developed and maintained by a community of volunteers and contributors, who provide support, documentation, bug fixes, and enhancements for the project. You can join the Firebird community through various channels, such as mailing lists, forums, blogs, social media, etc. Other RDBMSs may have different community structures and cultures, such as corporate-backed, foundation-based, or user-driven.
