Hi,

Don't worry, wlecome to Magma. I am one of the other Magma developers who works with Chris to develop Magma.
We use Magma in a telco environment and it surpassed our expectations.

May I suggest you install the 'Lava' and 'Lava testing' packages from SqueakSource.
Lava is a (beta) extension of Magma to provide a SQL interface to Magma.
That is, Magma collections can be wrapped in a SQL table schema and then queried using SQL.
The SQL is converted into Magma queries.
Now, obviously Magma offers more sophisticated collections and indices than a rectangular RDBMS table,
but the SUnit tests in the lava package have proven to be a useful tutorial for those coming from a RDBMS
as it shows how irregular data can be stored, indexed and retrieved.
Feel free to ask the list.
