Vendor's Description (from Readme files, web site, etc.):

NexusDB is an ultra-fast, client/server database engine originally designed for the Delphi and C++Builder developer. For the current version it has been extended to provide most of it's functionality to .NET programmers no matter which programming language they use.
NexusDB is nimble enough to be fully embedded into your desktop applications and powerful enough to be your primary database server.
NexusDB implements the international standard ISO/IEC 9075 - SQL:2003, including most of the Core SQL functionality as well as many of the additional features defined in the standard. In addition, NexusDB augments SQL:2003 with extensions to expose vendor-specific functionality.

Design goals NexusDB has been designed to maximize speed, minimize maintenance and p reserve data integrity. As a true client/server database, NexusDB is a unique component suite. This design decision has many benefits over typical file-based databases: better data integrity, better performance and better scalability.

Intuitive Developer Tools:

  • Enterprise Manager - full-featured tool to create and maintain databases, tables and SQL queries, all within an integrated workspace
  • Database Importers - import tables from other databases (FlashFiler, BDE, ADO) into NexusDB tables. Full source included that easily adapts to other databases
  • Source converter assistant - helps convert FlashFiler source code into NexusDB compliant source

SQL Support:

  • Standard SQL:2003 - statements supported
  • Triggers, Stored Procedures and Functions - fully implemented.
  • SQL/PSM Procedure Language - for server side programming.
  • Transaction Management and Referential Integrity - for professional data handling.
  • Fulltext Index Support - for fast data lookups.
  • ODBC Driver - access your data through industry standard ODBC
  • dbExpress Driver - use Borland's © components to query NexusDB

Flexibility of Deployment

  • Embedded - use NexusDB in your desktop applications; no dlls, COM objects or external dependencies
  • Client/Server Stand Alone - run as a networked server for your enterprise
  • Client/Server Windows Service - registered service with integrated event logging

Extraordinary Performance

  • Multi-Threaded Engine - utilizes Symmetric Multi-Processor systems to the fullest extent
  • New Memory Manager - maximizes allocation speed and minimizes fragmentation
  • Interchangeable data transports - optimized for deployment topology
  • Memory Tables - for the fastest possible data access

Client/Server Architecture

  • More Robust - server insulates physical data files from clients to prevent corruption
  • Increased Performance - server optimizes overall throughput
  • Better Scalability - can handle more simultaneous clients than file-based databases

Stability with Transaction Support

  • Snapshot Transactions - Unique to NexusDB, these transactions ensure that writers do not block readers
  • Fail-Safe Transactions - preserves the consistency of your data under the harshest of conditions with a complete two phase commit implementation
  • Nested Transactions - enables greater flexibility, clarity and encapsulation when using transactions


  • User connections - capable of hundreds of concurrent connections
  • Massive Data capacity - only limited by your OS and disk space; supports gigabytes of data comfortably
  • Record capacity - store millions of records effortlessly


  • Plugins - add new features to the core engine
  • Monitors/Extenders - intercept server events with Monitors and participate in their execution with Extenders
  • Sub-Engine registration - A NexusDB exclusive: customize storage, key comparisons, index structure, and many other aspects

Ease of Use

  • TnxTable/TnxQuery support - Native and familiar Delphi interfaces to access your data
  • Data-aware control compatibility - supports TDataset
  • Report Writer compatibility - use RAVE, Report Builder, FastReport and others
