About the full version

NexusDB is the most flexible full source database engine for Delphi and C++Builder users. It scales seamlessly from databases kept solely in memory, via embedded server (single executable deployment) to full C/S solutions scaling to hundreds of users.

• no royalty fees for server or client distribution.
• A large subset of SQL Ansi 92 is supported, including DDL.
• It adheres to the VCL TDataSet interface, so you can continue using all your favourite data-aware controls and report engines.
• In-memory table support which rivals pure memory-based database engines on speed on smaller datasets, while scaling very well to larger disk-based datasets (millions of records).
• In multi-user environments, only the server can access the data, minimizing risk of database corruption.
• Snapshot transactions provide 24/7 Live backup capability without disrupting regular database activity.
• Support for the IProvider interface (TClientDataSet) is included.
• The architecture is designed to be flexible, and can be enhanced by writing plugins, monitors and extenders.
• Free 3rd-party monitors/extenders already exist for custom client-server-client messaging (for instance, signal another client to

Features:

• This database is standalone, not based on BDE or another engines, need no Borland's data-access libraries to have. You need install no additional files.
• Quick access to stored data through indexes, finding and filtering methods,
• Store all data types (whole files as well as another data),
• Consists of the main non-visual components, and visual data-aware controls which worked together with the GBase tables: Grid, Edit, Label, ListBox, CheckListBox, ComboBox, Memo, RichEdit, ScrollPositioner, UpDownPositioner, ImgPositioner, MapPositioner,
• The possibility of import and export data from dBase tables,
• Included a TGReport - component to show and print reports from GBase tables,
• Included a TGTool - component to copy, pack, repair, import and export tables,
• The GBaseCreator (tool program to create table's structure), the help and examples are included too.

• This FREE version has limitation: You can append only up to 1000 records in one table,
• The PRO version (register at homepage) has no limitation and includes free update.

Main features:

• all standard properties, methods, events of TDataSet, working with any visual DB-aware controls;
• supporting most data types (including BLOB and autoinc fields), field descriptions, default values;
• record range and filter, sort-on-the-fly;
• cached updates, reverting records;
• temporary in-memory tables, automatic backup;

• callback events to visualization loading/saving process;
• properties ReadOnly for whole table and RecReadOnly for current record.

TurboDB implements an extensive sub-set of SQL 92 including primary and foreign keys, checks, all kinds of outer joins, correlated and uncorrelated sub-queries, UNION/EXCEPT/INTERSECT, the CASE construct and many more. Tables can be encrypted in various ways including Blowfish and AES. Full-text search is supported via special maintained, ultra-fast, customizable indexes. Transactions of isolation level "read committed" are implemented including automatic crash recovery.

The TurboDB package contains powerful native access components depending on the technology used. For the Borland tools, all standard VCL components like TDataSet are supported and provide almost the same interfaces as the BDE components. For the .NET tools, the native ADO.NET provider implements all standard interfaces and adds additional components for server-side cursors.

When deploying to the .NET platform, only two small additional libraries are required. With Delphi and C++ Builder, the database code can be compiled entirely into the application. On both platforms, no additional installation, registration etc. is needed. Copying the files is sufficient to run.

TurboDB inserts 10.000 records including one index into a small table in 350 ms on a mid-range single-processor computer and can calculate a join over six tables with 86 billion possible combinations in 100 ms.

The data is structured as named database and you can save any amount of data to exe.

To read data attached to exe, you don't have to extract it to temp dir.

In addition, with reader component, you can load attached data 1 by 1 into memory. It'll reduce memory consumption.

Useful to create installation, register or multimedia applications.
