That isn't really what Linked Data is about.
Using your MS Access and MS Excel analogies, when we talk about Linked 
Data, it's all about:

1. Excel Cell Names (in the form of hyperlinks) that resolve to data 
across networks
2. MS Access keys (in the form of hyperlinks) that resolve to data 
across networks .

Here is an example of a Spreadsheet and RDBMS combo doing Linked Data, 
as per  my comments above:

1. http://bit.ly/NkVEzD -- sparql describe against the 'Facebook' entity URI
2. http://bit.ly/Qc2GXX -- sparql select scoped to a named graph that 
holds the triples that describe the 'Facebook' entity .

Follow the links above and you get the combined effects of Excel and MS 
Access, as per my comments above.

Linked Data is about this form of fine grained data representation and 
access that scales to networks while also enabling the use of semantics 
to drive disparate data source integration and/or virtualization.

I would encourage you to add a Linked Data dimension to your service. 
Nothing about Linked Data makes it incompatible with functional and 
scalable business models. You just have to take that first step :-)
