3. Private Databases


3.1 Creating a Database

A searchable private database is created the first time that an entry is saved from PreQuest in the ASER format, with a specified name.

The database name is input without any extension, e.g. type mybase to create the relevant set of database files:

  mybase.ind
  mybase.msk
  mybase.tcd
  mybase.del
The mybase database is now searchable with Quest by employing the initialisation command line:

  quest junk -db mybase
To search the private mybase database first and then search the main CSD file (known as MASTER), type the following command line:

  quest junk -db mybase MASTER

3.2 Adding New Entries

Single entries, or a file of entries can be added to a private database by selecting the relevant Export option and specifying the name of the database to which the entries will be added. The format must be ASER. For example, to add entries to the mybase database simply type mybase in the File text box, select the ASER format and hit return. PreQuest will write the records with accompanying log messages appearing in the text window.

  writing entry # n - refcode
If a refcode matches an entry already present in the database it will not be written to the database and an error message will be issued. For this reason it is essential that each new entry has a unique refcode, usually an ascending numeric sequence (e.g. 00000001) of 8 characters.

3.3 Correcting Database Entries

Database entries can easily be corrected using PreQuest. Simply select the relevant database file, e.g. mybase.ind from the Open menu, and load. You then select and modify entries in the same way that you would for any other input file format. Each time that a different entry is selected you are prompted to save any changes already made.
