First of all you have to create tables for GNU Gama in SQLite database file
(here with db extension, but you can choose your own, e.g. sqlite).
$ sqlite3 gama.db < gama-local-schema.sql
You can check created tables by following commands (fist in command line, second in SQLite command line).
$ sqlite3 gama.db
sqlite> .tables
Output should look like this:
gnu_gama_local_clusters gnu_gama_local_descriptions
gnu_gama_local_configurations gnu_gama_local_obs
gnu_gama_local_coordinates gnu_gama_local_points
gnu_gama_local_covmat gnu_gama_local_vectors
When you have created tables you can import data. One way is to process file with SQL statements.
$ sqlite3 gama.db < geodet-pc.sql
Another way can be filing database file in another program.
For using sqlite3 command you need a command line
interface for SQLite 3 installed on your system (e.g. sqlite3 package).
