NAME

CPAN::SQLite::Populate - create and populate database tables

CONTENTS

DESCRIPTION

This module is responsible for creating the tables (if setup is passed as an option) and then for inserting, updating, or deleting (as appropriate) the relevant information from the indices of CPAN::SQLite::Info and the state information from CPAN::SQLite::State. It does this through the insert, update, and delete methods associated with each table.

Note that the tables are created with the setup argument passed into the new method when creating the CPAN::SQLite::Index object; existing tables will be dropped.

TABLES

The tables used are described below - the data types correspond to mysql tables, with the corresponding adjustments made if the SQLite database is used.

    mods

This table contains module information, and is created as



  mod_id INTEGER NOT NULL PRIMARY KEY
  mod_name VARCHAR(100) NOT NULL
  dist_id INTEGER NOT NULL
  mod_abs TEXT
  mod_vers VARCHAR(10)
  dslip VARCHAR(5)
  chapterid INTEGER



o mod_id

This is the primary (unique) key of the table.

o dist_id

This key corresponds to the id of the associated distribution in the dists table.

o mod_name

This is the module’s name.

o mod_abs

This is a description, if available, of the module.

o mod_vers

This value, if present, gives the version of the module.

o dslip

This is a 5 character string expressing the dslip (development, support, language, interface, public license) information.

o chapterid

This number corresponds to the chapter id of the module, if present.

    dists

This table contains distribution information, and is created as



  dist_id INTEGER NOT NULL PRIMARY KEY
  dist_name VARCHAR(90) NOT NULL
  auth_id INTEGER NOT NULL
  dist_file VARCHAR(110) NOT NULL
  dist_vers VARCHAR(20)
  dist_abs TEXT
  dist_dslip VARCHAR(5)



o dist_id

This is the primary (unique) key of the table.

o auth_id

This corresponds to the CPAN author id of the distribution in the auths table.

o dist_name

This corresponds to the distribution name (eg, for My-Distname-0.22.tar.gz, dist_name will be My-Distname).

o dist_file

This corresponds to the CPAN file name.

o dist_vers

This is the version of the CPAN file (eg, for My-Distname-0.22.tar.gz, dist_vers will be 0.22).

o dist_abs

This is a description of the distribtion. If not directly supplied, the description for, eg, Foo::Bar, if present, will be used for the Foo-Bar distribution.

o dist_dslip

This is a 5 character string expressing the dslip (development, support, language, interface, public license) information. Normally this comes from the module name; this value for the distribution name comes in simple cases where the module name matches the distribution name by a substitution of :: by -.

    auths

This table contains CPAN author information, and is created as



  auth_id INTEGER NOT NULL PRIMARY KEY
  cpanid VARCHAR(20) NOT NULL
  fullname VARCHAR(40) NOT NULL
  email TEXT



o auth_id

This is the primary (unique) key of the table.

o cpanid

This gives the CPAN author id.

o fullname

This is the full name of the author.

o email

This is the supplied email address of the author.

    chaps

This table contains chapter information associated with distributions. PAUSE allows one, when registering modules, to associate a chapter id with each module (see the mods table). This information is used here to associate chapters (and subchapters) with distributions in the following manner. Suppose a distribution Quantum-Theory contains a module Beta::Decay with chapter id 55, and another module Laser with chapter id 87. The Quantum-Theory distribution will then have two entries in this table - chapterid of 55 and subchapter of Beta, and chapterid of 87 and subchapter of Laser.

The table is created as follows.



  chap_id INTEGER NOT NULL PRIMARY KEY
  chapterid INTEGER
  dist_id INTEGER NOT NULL
  subchapter TEXT



o chap_id

This is the primary (unique) key of the table.

o chapterid

This number corresponds to the chapter id.

o dist_id

This is the id corresponding to the distribution in the dists table.

o subchapter

This is the subchapter.
