Bo has an additional member-crystal xcelsius, which has distinctive features in many bi products on the market:
The display format is Flash animation, and the screen is not worth mentioning.
By converting the usual dashboard into flash animation, a dynamic analysis method is provided. This is probably not available in other tools. Below is a simple sample generated by me. On the interface, it can dynamically change the growth rate.
The generat
provide a place for the data to survive.The PO is stateful, and each property represents its current state. It is the object representation of the physical data. Using it, we can decouple our programs from physical data and simplify the transformation between the object data and the physical data.3. Vo's properties are different depending on the current business, that is, each of its properties corresponds to the name of the data needed for the current business logic.The properties of the PO co

Settings are as follows
One, Po:persistant object persistent objects, can be seen as a Ava object mapped to a table in the database.The simplest PO is a record in a table in the corresponding database, and multiple records can be used in the PO's collection PO should not contain any operations on the database.Two, Vo:value object value objects. Typically used for data transfer between business tiers, as is the case with PO, which contains only data. But it should be abstracted out of business objects that can correspon

VO (Value object) value objectsTypically used for data transfer between business tiers, as is the case with PO, which contains only data. But it should be abstracted out of the business object that can correspond to the table, or not, depending on the needs of the business. Personally feel the same DTO (data transfer object) that is passed on the web.From the business model perspective, see the domain objects in the UML component Domain model. A Java object that encapsulates the business logic,
corresponding PO has 100 attributes.But we just show 10 fields on the interface,The client uses the Web service to get the data, and there is no need to pass the entire PO object to the client.At this point we can pass the result to the client with a DTO with only these 10 attributes, and this will not expose the service-side table structure. After the client is reached, if the interface is displayed with this object, then its identity will be converted to VO.O/R Mapper object/relationship Mapp
