The properties of a business view are:

Property Name | Description

Display Name | Specifies the display name of the business view. Data type: String
Maximum Duration | Specifies the maximum elapsed time allowed to fetch data from the data source when the business view runs, measured in seconds. If the value is set to zero or is blank, it means the time will be unlimited. For usage about the property, see Limiting the query run time and number of records. Data type: Integer
Maximum Rows | Specifies the maximum number of rows that will be fetched from the data source when the business view runs. If the value is set to zero or is blank, it means the number will be unlimited. For usage about the property, see Limiting the query run time and number of records. Data type: Integer
Prefetch | If true, when end user runs a web report or dashboard created on the business view, JReport will fetch all used data from the business view and reuse them afterwards. If false, JReport will query data on demand. When several business view elements are based on the same columns, they will reuse the columns. The property works on JReport Server. When the property is true, the List<ColumnInfo> parameter in the implementation class of the QueryOptimizer interface will include all columns in the business view, otherwise, it will only include columns used by the web report or dashboard. For business views in MongoDB and HIVE connections, the default value is false; for those in other connections, the default value is true. Data type: Boolean
