OptimAlj - A comprehensive speed and optimization of enterprise Java (3) uses the domain model editor provided by Optimalj, and designers can establish a corresponding domain model to open the entire development process. High-level and object-based domain models and UML compatible, including commercial transaction behaviors and information structures that need to be applied. In the domain model, the field levels, all levels of properties, associations, and rules, but does not cover detail information about true implementation or code. Based on the domain model, Optimalj generates various demonsions, business logic, and data models to ensure the various functions and criteria of the J2EE platform. The business rules editor is based on the business rules defined in OptimAlj, and designers can customize the application very conveniently. With the help of the Business Rule Editor, they can add a variety of static and dynamic business rules at the level of the model. Since the dynamic business rules are stored in a rule base, real-time dynamic modifications can be made in the actual application without having to modify the application itself. Due to the distinction between the business rules as independent and easy-to-identify elements in the model, the designers can quickly respond to changes in various business needs without the need for financial resources. The mode-driven generation process is a set of conversions and function modes in the core part of Optimalj. Optimalj uses the mode to generate the code required to run the application. The pattern can be utilized in accordance with the specific technical requirements of J2EE to utilize various optimal experiences. With the support of Optimalj, designers do not need to know all of J2EE's technical features, including Session Bean, Entity Bean, Message-Driven Bean, JSP, and application data tables. The result is that a group consisting of designers and developers can achieve high quality and coordinated application development results. A series of preset modes are available in OptimAlj. A simple and easy way to help designers apply various preset modes to significantly save time and avoid heavy implementation. Because the model itself is already a crystallization of knowledge and professional skills, it can help developers shorten their learning cycles for many times. It is also because the mode successfully liberates the experienced Java developers from cumbersome and easily generated the wrong low-level programming, so the use of the model can help developers significantly shorten the development time. After using the mode, you can release a lot of valuable Java developer resources in the Java development process, saving time and cost. Real-time synchronization because Optimalj establishes synchronization between Java code and application model, the model can always accurately represent the results of the application implemented. Such a synchronous relationship enables developers to modify the purpose of modifying applications only on the model's level. Optimalj can regenerate the part of the code affected by the modified model, minimizing the impact of the entire modification process itself. Compared with the modification of the traditional code, the operation here often only has only one third of the past. Optimalj ensures that all modifications will be consistent with existing application architectures. Among the entire development cycle, developers do not need to have an in-depth understanding of the application itself in the initial way to deal with modifications. Conversely, they can perform direct modifications at the level of the model, and by OptimAlj to ensure complete synchronization between the implementation code and the model.
