Body
Since .NET Framework 4.0 you can use Memory Mapped Files for this, I believe it would be faster than file system based approach since you do not need expensive file system IO operations. <blockquote> A memory-mapped file contains the contents of a file in virtual memory. This mapping between a file and memory space enables an application, including multiple processes, to modify the file by reading and writing directly to the memory. Memory-mapped files can be shared across multiple processes. Processes can map to the > same memory-mapped file by using a common name that is assigned by the process that created the file </blockquote> So to share MMF across multiple processes you just need to share a MMF name, so you can consider following approach: <ul> <li>Engine creates MMF file and share with Viewer just a name (string)</li> <li>View access MMF using <a href="http://msdn.microsoft.com/en-us/library/system.io.memorymappedfiles.memorymappedfile.openexisting.aspx" rel="noreferrer">MemoryMappedFile.OpenExisting(sharedName)</a> method (see <a href="http://msdn.microsoft.com/en-us/library/dd997372.aspx" rel="noreferrer">MSDN</a> for an example accessing same MMF from different processes)</li> </ul> Useful links: <ul> <li><a href="http://msdn.microsoft.com/en-us/library/dd997372.aspx" rel="noreferrer">Memory-Mapped Files</a></li> <li><a href="http://blogs.msdn.com/b/salvapatuel/archive/2009/06/08/working-with-memory-mapped-files-in-net-4.aspx" rel="noreferrer">Working with memory mapped files in .NET 4</a> - highly recommend reading this article which describes why MMF really <code>"is the most efficient way for multiple processes on a single machine to communicate with each other"</code>. Basically it show that all other IPC options are MMF-based. </li> </ul> (From the mentioned above article) If we check other IPC methods we can see the following architecture: <img src="https://i.stack.imgur.com/Dzmni.png" alt="enter image description here">

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
