In order to solve a series problems such as systemic redundancy and transplantation difficulty caused by the differences in driver API,database DDL and DML language,the ADO.NET multi-database access,a data access layer interface and product family is designed based on the separation model between product creating liability and consumer liability in abstract factory pattern.It achieves the ADO.NET cross-database access and the dynamic transplant across multiple databases.It is demonstrated that the method provides a flexible and dynamic extension mechanism for data access layer and effectively reduces the coupling between the business layer and data access layer.
