Database Comparer VCL (DBC VCL) compares and synchronizes databases structure (metadata) and table data for many popular databases.

Currently supported databases: Oracle, MSSQL, MySQL, InterBase (FireBird, Yaffil), Sybase, Postgre SQL. This list is constantly updated and support for other databases will be added soon.

Most popular database engines such as ADO, BDE supported directly. Also database specific libraries such as IBX, FIB, IBO, ZEOS, AnyDAC etc supported as well.

The library includes more than 25 components for Database development and its code is constantly being refined and improved.

Features at a glance:
- Can compare database with database, database with SQL/DDL script and SQL/DDL script with SQL/DDL script.
- Can compare and synchronize data between two database tables.
- Extracting the database metadata.
- You can optionally select which objects (domains, tables, procedures, triggers etc.) should be compared.
- Royalty free licensing. Free Unlimited Email support.
- Fully-indexed help documentation. Delphi, C++Builder and Visual Basic demos code.

Database Comparer VCL library comes with full sources (demo versions does not have sources), detailed help and demo projects.

EMS Data Generator for PostgreSQL is a powerful utility for generating test data to several PostgreSQL database tables at once. The wizard application allows you to define tables and fields for generating data, set value ranges, generate char fields by mask, load values for BLOB fields from files, get lists of values from SQL queries and many other features to generate test data in a simple and direct way. It also provides you console application, which allows you to generate data in one-touch by using generation templates.

Features:

- User-friendly wizard interface;
- Generating data to several tables from different databases on one host;
- All PostgreSQL data types including array, network address and geometric types;
- Different generation types for each field including list, random, incremental data generation and more;
- Ability to use SQL query results as list of values for data generation;
- Automatic control over referential integrity for linked tables data generation;
- Wide variety of generation parameters for each field type;
- Ability to set NULL values for certain percent of cases;
- Possibility of saving all the generation parameters, set on current wizard session;
- Command-line utility to generate data using the template file.

A report by the School of Computer Engineering's department of Automatic Control and Systems Engineering at University of Vigo, named "Report on the performance of different Database Management Systems (DBMS)" , concludes that Velneo performs better than the both database market giants.

After undergoing several speed and performance trials, the overall results from this link to the academic benchmark report reveal that Velneo is faster than SQL-Server, and that SQL Server is faster than Oracle.

All test results were measured in milliseconds. They can be seen in this microsite.
If we focus on transactional operations (new record, edit record and delete record) performed by the different database management systems, the tests conducted at the University show that Velneo finishes either first or second (usually behind SQL Server and in front of Oracle Database) in all transactional operations.

Velneo can't be compared to with products that are not CASE tools or fourth generation languages. I am not sure if products like Visual Basic, Delphi and part of the .NET philosophy can be considered fourth generation. From where I see it, CASE tools are those that really perform assisted programming functions, not simply managing windows, events and passing messages or communication with external SGBDs. Velneo, if compared to the products above, is a technological revolution in the world of software development because the assisted programming concept is taken to the extreme limit.

With Visual Basic the whole thing is code and its uneatable syntax can get you into trouble. With Velneo, if you develop properly, rarely are you going to have to write on single code line (unless you have to perform very specific and critical tasks that are a bit off the Velneo field -business and information management solutions).
