Appian ACD200 Exam With Confidence Using Practice Dumps

A joining table can be used to hold instances of Student/Class relationships, so that it can be supported in Appian and remain in at least First Normal Form. A joining table is a table that contains only foreign keys that reference the primary keys of other tables. A joining table can be used to model a Many-to-Many relationship between two entities, such as Student and Class. For example, a joining table called Enrollment could have two columns: Student_ID and Class_ID, which reference the primary keys of the Student and Class tables respectively. Each row in the Enrollment table represents an instance of a student enrolled in a class. References: [Joining Tables], [Many-to-Many Relationships], [First Normal Form]

The question is about the recommendations for Appian environment to address the performance risk of a large increase in users. The following are two recommendations for this purpose:

• Add more process execution engines. This means adding more servers or nodes that can execute process instances in parallel, which can improve the scalability and availability of Appian. This can help handle the increased workload and demand from more users without affecting the response time or reliability of Appian.
• Add more application server memory. This means increasing the amount of memory allocated to each server or node that runs Appian components, such as web servers, engines, or analytics servers. This can help improve the performance and stability of Appian by reducing memory pressure and garbage collection.

The following are not recommendations for Appian environment to address the performance risk of a large increase in users:

• Add more design engines. This means adding more servers or nodes that can execute expression rules or interface components in parallel, which can improve the performance and scalability of Appian. However, this is not directly related to the number of users, but rather to the complexity and frequency of expression rules or interface components in the application.
• Switch from a records-centric to a process-centric design. This means changing the application design to focus more on process models and tasks, rather than records and reports. This does not affect the Appian environment, but rather the application logic and functionality. This may or may not improve the performance of the application, depending on the requirements and use cases.
