the technology used to run the middle tier in three-tier architecture
This is a computing rather than an insurance term. "Middle layer" refers to a three-tier architecture, in which, in addition to the client tier (user interface) and the database tier (DBMS server) there is an intermediate application server tier. This is necessary when there are a large number of on-line users, in a large enterprise, because in those circumstances problems arise with a two-tier architecture. Performance deteriorates, for various reasons, when a large number of clients are connecting directly to the DBMS server. So a middle tier is introduced to handle the connections.
"TIA has a 3-tier, Service Oriented Architecture separating Client Tier from Application Server Tier from Database Tier.
The Client Tier supports multiple front ends types for the Intranet, Extranet, and Internet, all leveraging the same business logic thereby securing instant access to data from all channels.
The Application Server Tier processes requests to the business logic. Common java API’s secure openness and connectivity and supports multiple technologies, e.g., java, .net, etc. The insurer decides on middle layer technology.
The Database Tier contains data and business logic to secure highest performance across any channel with minimal network traffic."

"The industry's response to limitations in the 2-tier architecture has been to add a third, middle tier, between the input/output device (PC on your desktop) and the DBMS server. This middle layer can perform a number of different functions - queuing, application execution, database staging and so forth. The use of client/server technology with such a middle layer has been shown to offer considerably more performance and flexibility than a 2-tier approach.
Just to illustrate one advantage of a middle layer, if that middle tier can provide queuing, the synchronous process of the 2-tier approach becomes asynchronous. In other words, the client can deliver its request to the middle layer, disengage and be assured that a proper response will be forthcoming at a later time. In addition, the middle layer adds scheduling and prioritization for the work in process. The use of an architecture with such a middle layer is called "3-tier" or "multi-tier". These two terms are largely synonymous in this context."

"...ASP is also the glue between 2 important layers (at the simplest view) in this tiered model that you are talking about - The Presentation (which includes mark-up, styling, and light business logic e.g. client-side scripts) and The Application (called many other things e.g. Business Layer, Middle Layer)(which includes your core business objects) containing light business logic that is not to consume much of the interpretation time..."

"The Strategic Vision set out a future IM&T direction that was founded on strong governance,
best of breed departmental systems and described a Middle Layer technology that would
deliver a comprehensive electronic medical record (EPR). The vision also recognised the
need for the Trust to replace the Patient Administration System (PAS), a key component for
any acute trust.
The Middle Layer technology not only provides an EPR but also provides a capability for the
organisation to collect key data at a time and place that is most appropriate for the delivery of
care. This solution provides flexibility for CHUFT to respond to changing needs in a way that is
not accessible through current contracts with major PAS and EPR suppliers. ..."

so yes, it's computing terminology

ADO is a middle-layer technology...it depends on OLE DB...which in turn depends
on its low-level providers to support the functions. Most likely,
Jet.OLEDB.3.51 doesn't support the function, you'll need to use the
Jet.OLEDB.4.0 provider to get the functionality. You should be able to create
it in 3.51 format, but read it in 4.0 when neccessary...but take care...it may
bite you in the end (no pun intended).
