  10. Support for MongoDB either in UniDAC or as a separate VCL product

    I'd like to see UniDAC support MongoDb which is a scalable, NoSQL database that supports replication, high availability, auto-sharding, indexing, querying, GridFS (large files), stores BSON documents (binary JSON). MongoDB is ideal for storing large amounts of text or binary data, and makes it ideal for web sites with huge amounts of data that can't be handled by conventional relational databases like MySQL or Oracle.

    Customers include Disney, Craigslist, Forbes, Spike, Intuit, Sourceforge, New York Times ...

    See www.mongodb.org for more info on this free open source database.

  11. Support SQLite in a separate product

    Currently we provide UniDAC components for working with SQLite. UniDAC are universal component for database access, they provide universal interface for working with different databases. As it is a universal product, it may lack support for some specific database features in some DBMS.

    If we separate SQLite database access to a dedicated product, this will allow support for all specific SQLite features and make SQLite access cheaper, because this product will cost less than UniDAC.

  12. Direct mode connections in FreePascal (Linux and MS Windows)

  13. Implement compression to get most out of the FireBird 3

    Firebird 3 supports the compression between client and server.

    If possible implement this, it would make significant impact to the speed on slow connection (especially with large queries)

    Hello,

    We supported Firebird compression in IBDAC 6.4.1.
    You can enable it using the WireCompression parameter:
    IBCConnection1.Params.Add(‘WireCompression=true’);

    Please note that you should use the zlib1.dll library, which has matching bitness. The zlib1.dll library should be placed in the directory with your executable file. Please make sure that your application uses the library the TIBCConnection.Connect method is called.

  14. Add a method to empty table

    Add a method to empty table (delete all the table data). For example, it may be called EmptyTable.

  15. Save empty string fields as NULL

    Some databases allow saving an empty string optionally as NULL or as empty string. Query result can differ depending on how the string was saved.

    select *
    from test_table
    where str is null
    will return strings that were saved as NULL values

    select *
    from test_table
    where str = ''
    will return strings that were saved as empty strings

    We can add an EmptyStringAsNull option, which will force saving empty strings as NULL values.

  18. Creating a provider for DBF

    Creating a separate provider for working with DBF databases will simplify opening such databases (you will need to specify only a path to the DBF files) and will provide support for some specific features of this database.
