Database tables

Version:

Only available versions of this content are shown in the dropdown

Create database table data instances to map classes or class groups to database tables or views. You can use the Database Table form to revise existing class-to-table relationships.

The local data storage format replaced data tables. You can convert existing data tables on the Data Table landing page, which you can access by clicking Configure Data Model Data Tables . For more information, see Creating local data storage.

Fields and controls

The following table describes the available options for relational databases on the Database Table form.

Field Description
Database Identify a database instance that corresponds to the database containing the table or view.
Reports Database Optional. Identify a database instance that contains a copy of this table, replicated through database software.

Complete this field only if a database administrator has created a mirrored replica of all or part of the PegaRULES database that is sufficient to support reporting needs, and established a replication process. To reduce the performance impact of report generation, you can specify that some or all reports obtain data from the reports database.

The sources for a report cannot span multiple databases. If a report definition presents data from multiple tables, all required tables must be in one database. This database can be either the PegaRULES database or a single reports database.

Catalog Name

Optional. Identify the database catalog containing the schema that defines the table or view.

In special situations, a catalog name is needed to fully qualify the table.

Schema Name

Optional. Identify the name of the schema (within the catalog) that defines the table. The schema name is required in some cases, especially if multiple PegaRULES database schemas are hosted in one database instances.

Table Name Enter the name of the specific table that is to hold instances of the specified class or class group.

When allowed by the database account, enter only an unqualified table name. Preferably, the database account converts the unqualified table name to the fully qualified table name.

A few of the database table instances that are created when your system is installed identify database views rather than tables. Views are used only for reporting. By convention, the names of views in the initial PegaRULES database schema start with pwvb4_ or pcv4_.

If you create additional views in the PegaRULES database, you can link to them to a class using a database table instance. The view data then becomes available for reporting.

Test Connectivity After you save this Data Table form, you can test connectivity to the database and table. This test does not alter the database. The test uses information on this form, the associated database data instance, and in some cases, information from the prconfig.xml file, dynamic system settings, or application server JDBC data sources.

The following table describes the available options for NoSQL databases on the Database Table form.

Field Description
Database Identify a database instance that corresponds to the database containing the table or view.
Table name This field is displayed for Apache Cassandra databases only. Enter the name of the table in which to store data.
Time-to-Live in seconds (0 = no expiration) Specify the number of elapsed seconds until a NoSQL document expires. The current TTL is applied whenever a document is saved or updated. For example, 25000. If not specified or set to zero, documents will not expire.

For Couchbase databases, valid values are 0 to 20*365*24*60*60.

Changing this value does not affect existing data.
Test Connectivity After you save this Data Table form, you can test connectivity to the database and table. This test does not alter the database. The test uses information on this form, the associated database data instance, and in some cases, information from the prconfig.xml file, dynamic system settings, or application server JDBC data sources.
