From Zero To One

OmniXML based storage suited for easy XML data management, data storage and data interchange beetween systems. Main features are:

• flexibility and unlimited storage depth
• ease of use (enumerations, blind access…)
• can store any data type including binary data
• support for custom data filters (compression…)
• support for data adapters (TDataSet…)
• build in encryption support
• build in support for handling collections
• basic XPath support for searching

To demo bellow shows the power of SimpleStorage. It stores and compresses a jpeg image and then retrieves that same image back from the storage.
If you have trouble using the code or have any other questions, please contact me directly using the “Contact” page.

  MS := TMemoryStream.Create;
  try
    Jpeg.SaveToStream(MS);
    MS.Position := 0;
 
    SrcStorage := CreateStorage('BinaryStorage');
    SrcStorage.Ensure('Image').Filter('gzip').AsBinary.LoadFromStream(MS);
  finally
    MS.Free;
  end;

  Jpeg := TJPEGImage.Create;
  try
    Jpeg.LoadFromStream(SrcStorage.Get('Image').Filter('gzip').AsBinary.Stream);
  finally
    Jpeg.Free;
  end;
