FbNetExternalEngine - running .NET code as a procedure, etc. in Firebird

Firebird 3 introduced plugins that allow you to execute any code and return some data back - triggers, stored procedures and functions to be precise. Similar to old UDFs, but as a plugin. The FbNetExternalEngine uses this and allows you to have a logic written in any .NET language, like C#, and use it as a function for example. So you have all the power of .NET ecosystem inside Firebird.
What's new in .NET driver for Firebird

Over the last few years and months, the .NET driver for Firebird was making a progress for more complete ADO.NET provider, with fewer bugs and more performance. In this session, I'll look at all the improvements and all the drivers (and possibilities) available.
Using Firebird with .NET Core and Entity Framework Core

.NET Core run on Windows, Linux, and MacOS and so does Firebird. Why not take the advantage and create new applications on .NET Core, using Entity Framework Core, and as a storage use Firebird.
Comparing Firebird databases with FirebirdDbComparer

Managing changes in database structures are difficult. Especially if you have multiple versions up in the air. FirebirdDbComparer is a new library that allows you to do the compares, trying to create the script as a sane person would do. Either you can use it as a library and use it from within your application or as a standalone executable.

Tuning Linux and Firebird for 660Gb database and 1500 connections

The session will be devoted to the practical steps which were taken to optimize several real-world high-load systems, with databases size up to 660Gb and 1500 users in peak, running on Linux.
We will also discuss the hardware choice and problems, related to Virtual Machines, popular mistakes in the setup of the high-performance system, reasons for various Firebird mistakes, and the logic behind the OS and firebird.conf settings.
As a final step, we will present the check-list for building the high-performance system with Linux and Firebird.
Recovery of Firebird Databases

Despite the fact that Firebird 3 is much more stable than previous versions, database corruptions still happen: mostly caused by hardware crashes and by ransomware. This session will be devoted to the experience of IBSurgeon in recoveries of very big databases, ransomware-encrypted database, recovery of the databases encrypted by the encryption plugin, broken nbackup delta files, and other interesting cases.
We will present the algorithm for the database recoveries with the standard tools (gfix, gbak) and with third-party recovery tools (IBSurgeon FirstAID).

RedDatabase in the Enterprise: 3Tb database with 2000 connections with 99,9% availability

RedDatabase is an enterprise-ready database system. It is included in the list of software permitted to be used in Russian government systems and has a security certificate. There are a lot of installations in different types of information systems. This session will talk about several ones.
The flagship project of Red Soft which uses RedDatabase is the information system of the Federal Bailiff Service (FBS).
One of the important tasks for the FBS system is the exchange of documents with other services such as banks. Availability of the database must be at least 99.9%. In this talk, we will describe the design of the applications and databases.
You will see the solutions for real-world problems on real-world examples:
  • database size is 3 TB
  • the database has tables with 12 columns and contains up to 1.5 billion records.
  • every day about 3 million new records are inserted or updated
  • each table has a foreign key with BIGINT data type. A query with search by this key takes less than 100 ms.
  • about 2000 clients concurrently use the database.
We will also describe several other solutions as well.
Overview of RedDatabase 4.0

RedDatabase is based on Firebird and is actively developed by the team at Red Soft.
We try to keep versions in sync with Firebird by developing every branch in close collaboration with the Firebird Project team. A lot of RedDatabase features have already been ported into Firebird version 3.0 and 4.0. This session is devoted to the history of RedDatabase, and its development process. We will present new features that have been implemented in RedDatabase and are currently not available in Firebird. We will also present a draft of the RedDatabase 5.0 roadmap.

Brief architecture and ideology reminder
    • three tier JEE application design tool
    • tasks of each tier, ways of accomplishment
    • easy to grasp for database specialists
New features since 2016:  Changed licensing to free for all supported databases, Javascript Gateway, Way of inclusion of external Javascript libraries, Multi-language applications support, bidirectional (rtl,ltr) applications support, designer designs ltr, and the execution engine selects the direction, based on the browser locale, add hoc sorting of query results, CSV and HTML query results download, Teradata support
Towards legacy applications migration
Today in most of the cases the demand is for migration or extension of legacy applications. The design of new applications is very seldom met.
    • Server side host command line execution (quasi CGI) allowing to integrate with any available programming language. This gives the possibility to save the development effort put into the design.
    • “Poor man’s” report server for almost any reporting tool. 
    • multi column primary keys
    • lessening of primary key columns requirements.
Towards SaaS model
The ways of moving Single Business entity applications to separate multiple Business entity web application with CloudaIDE, allowing to offer solutions in SaaS model.
