    <p>Part of the problem you are having is that you are trying to store schema-less data in a SQL database, which is not its strength. There are three approaches that would make your life far easier:</p> <p>1) Have a column which stores the serialized custom fields, with whatever format is mst convenient. For example, this column could store xml. Upsides are that you can use SQL Server Compact and pulling back a record is trivial. Downsides are that you always have to pull/push the entire xml blob to do an update, and it is difficult to impossible to query on any custom fields.</p> <p>2) Upgrade to SQL Server Express, and use XML columns. This is nearly the same as the first suggestion, except that any server ready version of SQL Server has native support for XML data. These columns can have indexes added and fields within the data can be used in queries.</p> <p>3) Use a Schema-less Database, like MongoDB or CouchDB. These databases are all about storing schemaless data, so your custom fields will be no different than any other field. As such, you can index and query custom fields. Upsides are that custom data is incredibly easy to work with, downsides are that you would have to spend some time rethinking how you store data to fit within their model.</p> <p>If you do not need to query based on custom fields, or if you can query custom fields within business logic, then the first option can work for you. In any other case, I would err towards something with more capabilities than compact. If cost is the deciding factor, both SQL Server Express and MongoDB are free.</p>

    1. COLooked at nosql earlier and while promising the base model here is still relational ! sql compact has minimal footprint compared to sql express though the new sql localdb looks promising but too late to change at this stage

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.
