| 42 : | sh002i | 956 | =head1 DESCRIPTION |
| 43 : | |||
| 44 : | WeBWorK::DB provides a consistent interface to a number of database backends. | ||
| 45 : | Access and modification functions are provided for each logical table used by | ||
| 46 : | the webwork system. The particular backend ("schema" and "driver"), record | ||
| 47 : | sh002i | 1696 | class, data source, and additional parameters are specified by the hash |
| 48 : | referenced by C<$dbLayout>, usually taken from the course environment. | ||
| 49 : | sh002i | 956 | |
| 50 : | =head1 ARCHITECTURE | ||
| 51 : | |||
| 52 : | The new database system uses a three-tier architecture to insulate each layer | ||
| 53 : | from the adjacent layers. | ||
| 54 : | |||
| 55 : | =head2 Top Layer: DB | ||
| 56 : | |||
| 57 : | The top layer of the architecture is the DB module. It provides the methods | ||
| 58 : | listed below, and uses schema modules (via tables) to implement those methods. | ||
| 59 : | |||
| 60 : | sh002i | 1568 | / new* list* exists* add* get* get*s put* delete* \ <- api |
| 61 : | sh002i | 956 | +------------------------------------------------------------------+ |
| 62 : | | DB | | ||
| 63 : | +------------------------------------------------------------------+ | ||
| 64 : | \ password permission key user set set_user problem problem_user / <- tables | ||
| 65 : | |||
| 66 : | =head2 Middle Layer: Schemas | ||
| 67 : | |||
| 68 : | The middle layer of the architecture is provided by one or more schema modules. | ||
| 69 : | They are called "schema" modules because they control the structure of the data | ||
| 70 : | for a table. This includes odd things like the way multiple tables are encoded | ||
| 71 : | sh002i | 1012 | in a single hash in the WW1Hash schema, and the encoding scheme used. |
| 72 : | sh002i | 956 | |
| 73 : | The schema modules provide an API that matches the requirements of the DB | ||
| 74 : | layer, on a per-table basis. Each schema module has a style that determines | ||
| 75 : | which drivers it can interface with. For example, WW1Hash is a "hash" style | ||
| 76 : | schema. SQL is a "dbi" style schema. | ||
| 77 : | |||
| 78 : | =head3 Examples | ||
| 79 : | |||
| 80 : | Both WeBWorK 1.x and 2.x courses use: | ||
| 81 : | |||
| 82 : | / password permission key \ / user \ <- tables provided | ||
| 83 : | +-----------------------------+ +----------------+ | ||
| 84 : | | Auth1Hash | | Classlist1Hash | | ||
| 85 : | +-----------------------------+ +----------------+ | ||
| 86 : | \ hash / \ hash / <- driver style required | ||
| 87 : | |||
| 88 : | WeBWorK 1.x courses also use: | ||
| 89 : | |||
| 90 : | / set_user problem_user \ / set problem \ | ||
| 91 : | +-------------------------+ +---------------------+ | ||
| 92 : | | WW1Hash | | GlobalTableEmulator | | ||
| 93 : | +-------------------------+ +---------------------+ | ||
| 94 : | \ hash / \ null / | ||
| 95 : | |||
| 96 : | The GlobalTableEmulator schema emulates the global set and problem tables using | ||
| 97 : | data from the set_user and problem_user tables. | ||
| 98 : | |||
| 99 : | WeBWorK 2.x courses also use: | ||
| 100 : | |||
| 101 : | / set set_user problem problem_user \ | ||
| 102 : | +-------------------------------------+ | ||
| 103 : | | WW2Hash | | ||
| 104 : | +-------------------------------------+ | ||
| 105 : | \ hash / | ||
| 106 : | |||
| 107 : | =head2 Bottom Layer: Drivers | ||
| 108 : | |||
| 109 : | Driver modules implement a style for a schema. They provide physical access to | ||
| 110 : | a data source containing the data for a table. The style of a driver determines | ||
| 111 : | sh002i | 1012 | what methods it provides. All drivers provide C<connect(MODE)> and |
| 112 : | C<disconnect()> methods. A hash style driver provides a C<hash()> method which | ||
| 113 : | returns the tied hash. A dbi style driver provides a C<handle()> method which | ||
| 114 : | returns the DBI handle. | ||
| 115 : | sh002i | 956 | |
| 116 : | =head3 Examples | ||
| 117 : | |||
| 118 : | / hash \ / hash \ / hash \ <- style | ||
| 119 : | +--------+ +--------+ +--------+ | ||
| 120 : | | DB | | GDBM | | DB3 | | ||
| 121 : | +--------+ +--------+ +--------+ | ||
| 122 : | |||
| 123 : | / dbi \ / ldap \ | ||

| 127 : | |||
| 128 : | sh002i | 1012 | =head2 Record Types |
| 129 : | |||
| 130 : | In C<%dblayout>, each table is assigned a record class, used for passing | ||
| 131 : | complete records to and from the database. The default record classes are | ||
| 132 : | subclasses of the WeBWorK::DB::Record class, and are named as follows: User, | ||
| 133 : | Password, PermissionLevel, Key, Set, UserSet, Problem, UserProblem. In the | ||
| 134 : | following documentation, a reference the the record class for a table means the | ||
| 135 : | record class currently defined for that table in C<%dbLayout>. | ||
| 136 : | |||

| 156 : | sh002i | 1012 | The C<new> method creates a DB object and brings up the underlying |
| 157 : | sh002i | 1035 | schema/driver structure according to the C<%dbLayout> hash in C<$ce>, a |

| 187 : | |||
