This section describes:

Generating business-object-level properties

i2ADWODA generates the following information at the business-object level:

Application-specific information at the business-object level allows you to:

At the business-object level, application-specific information format consists of parameters separated by semicolon (;) delimiters. The name of the parameter and its value are separated by a colon (:) delimiter. The syntax is:

TN=TableName; SCN=StatusColumnName:StatusValue

where TableName identifies the database table, StatusColumnName is the name of the database column used to perform logical deletes, and StatusValue is the value that signifies that a business object is inactive or deleted.

The AppSpecificInfo that i2ADWODA generates at this level contains a value only for the name of the database table, view, stored procedure, or synonym/nickname. For information on specifying a value for the status column, see Application-specific information at the business-object level.

Attribute properties

This section describes the properties that i2ADWODA generates for each attribute. For more information about the attributes, see "Business object attribute properties".

Name property

i2ADWODA obtains the value of the attribute's name from the column name in the database table or view.

Data type property

When setting the type of an attribute, i2ADWODA converts the data type of a column in the table or view to a corresponding IBM WebSphere Business Integration Adapter Business Object type. This conversion is done in two steps. First, the data type in the database is converted to a JDBC type. Then, the JDBC type is converted to an IBM WebSphere Business Integration Adapter Business Object type. The first conversion is done by the JDBC driver that you are using. Please consult the documentation of the JDBC driver that you are using. Please refer to the JDBC specification (2.0 and above) for details on individual database type mapping to a JDBC type. Table 14 shows the conversion from the JDBC Type to the corresponding IBM WebSphere Business Integration Adapter Business Object type.

Note:
If a column's data type is not one of those shown in Table 15, i2ADWODA skips the column and displays a message stating that the column cannot be processed.

Cardinality property

i2ADWODA sets the cardinality of all simple attributes to 1.

MaxLength property

i2ADWODA obtains the length of a string from the length specified for the varchar, char, or text data type.

IsKey property

If the column is a primary key in the table, i2ADWODA marks it as a key attribute. However, if a view, instead of a table, is selected as the source node to generate Business Objects, i2ADWODA does not mark the column as a key attribute. In this case, the key attribute needs to be set manually.

IsForeignKey property

i2ADWODA does not set the IsForeignKey property. You can set it in Business Object Designer.

IsRequired property

If a field is designated not null in the table or view, i2ADWODA marks it as a required attribute. However, i2ADWODA does not mark the key field as required because there may be a sequence associated with it, or it may be an identity column.

AppSpecificInfo property

i2ADWODA includes two parameters for the AppSpecificInfo property at the attribute level. The syntax of the specified parameters are:

CN=ColumnName

where ColumnName is the name of the column in the database table or view associated with the specific attribute.

BYTEARRAY=true|false

i2ADWODA recognizes columns with binary data and creates an attribute of type String with an AppSpecificInfo property of BYTEARRAY=true.

Note:
You can set additional AppSpecificInfo parameters in Business Object Designer. For information about these parameters, see Application-specific information at the attribute level.

Verbs

i2ADWODA generates the verbs specified in the BO Properties window. It creates an AppSpecificInfo property for each verb but does not populate it. For more information, see Application-specific information format for verbs.
