Design And Implementation Of ORM Tool’s Interface Based On Java Technology

All research, design and realization of the target database (Table/maps/synonymous)securing a direct visit to the class for programming staff to the development staff can useobject-oriented code described structured SQL statements. This is a lightweight of ORMcomponents.After using the ORM, the project development will become more efficient, since thedevelopers of program will not waste time and attention on the SQL statement or JDBCdevelopment any longer. For the operations of database, the ORM frame had put them intoconvenient object operation. So program developers only need to master the object-orienteddevelopment, and they can develop the database application. It is no doubt that with theapplication of ORM the expansibility and maintainability of the system will be increasedgreatly. Moreover, the coupling between the data layer and business layer will reduce greatly.The developers are able to be liberated from the low-level repetition labor, and they could paymore time and attention into those actual business needs. On the other side, for the projectitself, the cost will reduce either.The main focus on: Designed to achieve a weight ORM components based on Javatechnology–Nemo: Nemo is a Java technology-based lightweight components of ORM. Byusing this middleware, Java and data access SQL (Structured Query language) statementrealize the connection. It can type in the relationship between objects and database for anautomatic shine upon so that we operate in a specific database, there was no need andcomplex SQL statements deal, as long as it operated at the same database can operate, Nemowill automatically be converted to operate at the SQL statements for the operation, so that weonly need to concern business logic of the target structure, rather than the bottom repetitivedatabase SQL and JDBC code; The design of Nemo components:The core idea is to ORMrelationship shine upon a target in meeting the needs of most projects premise of ORM components for simplified design ideas; The database connectivity and interface design ofNemo components:How would such a database table shine upon documents, and throughinterfaces to SQL statements generated by the process of programming language, which is thefocus of this paper; The application and testing of Nemo components,Nemo components ofthe configuration introduced, and produced simple enquiries, deleted, modified and additionaltesting code, the use of the components of the test.
