## Collect information about the package annotation DB

### Description

Some convenience functions for getting a connection object to (or collecting information about) the package annotation DB.

### Usage

      illuminaMousev1p1BeadID_dbconn()
      illuminaMousev1p1BeadID_dbfile()
      illuminaMousev1p1BeadID_dbschema(file="", show.indices=FALSE)
      illuminaMousev1p1BeadID_dbInfo()

### Arguments

`file` | A connection, or a character string naming the file to print to (see the `file` argument of the `cat` function for the details).
`show.indices` | The CREATE INDEX statements are not shown by default. Use `show.indices=TRUE` to get them.

### Details

`illuminaMousev1p1BeadID_dbconn` returns a connection object to the package annotation DB. IMPORTANT: Don't call `dbDisconnect` on the connection object returned by `illuminaMousev1p1BeadID_dbconn` or you will break all the `AnnDbObj` objects defined in this package!

`illuminaMousev1p1BeadID_dbfile` returns the path (character string) to the package annotation DB (this is an SQLite file).

`illuminaMousev1p1BeadID_dbschema` prints the schema definition of the package annotation DB.

`illuminaMousev1p1BeadID_dbInfo` prints other information about the package annotation DB.

### Value

`illuminaMousev1p1BeadID_dbconn`: a DBIConnection object representing an open connection to the package annotation DB.
`illuminaMousev1p1BeadID_dbfile`: a character string with the path to the package annotation DB.
`illuminaMousev1p1BeadID_dbschema`: none (invisible `NULL`).
