## Database and SQL

Use your skills to explore the database using SQL, as appropriate. Keep in mind:

- You are working in a typical IBM i development environment. A data library is included on your library list.
- It's normal that data files are not present in your build/task library.
- Don't try to query SYSTABLES to discover what tables are available. Rather, look at the physical (.pf) and logical (.lf) file sources and SQL sources in the repo to determine what tables are available.
- Table layouts can be discovered by interpreting the source code. You can also query the table with your SQL skill to return the table layout metadata along with query results.
- It's not necessary to qualify table names with a schema/library in queries. Just refer to the known table names in the project and they will be found on your library list.
- Do not attempt to use any tables that are not present in the source repo.
- Do not attempt to alter existing tables unless specifically asked to.
