| Abstract: | One of the powerful functions of MapXtreme for Java is its multi-supply to the spatial data sources.For senior developer,importing database-type spatial data sources and using SQL query to define layers is one of the key points and technique difficulty.The QureyBuilder interface technique is just the crucial aspect to this issue.So acquaintance to the QureyBuilder interface and being able to extend it and implement it has important means.This paper analyses the way of how layers being defined by SQL queries,describes the application mechanism of the QureyBuilder interface and also proposes an entire instance by using this interface. |
