Reporting Design Patterns

Reporting design patterns are an important part of the object-oriented design of InetSoft Enterprise products. The use of design patterns not only facilitates ease of use; it also helps programmers understand the high-level framework behind the object design. This chapter documents the design patterns used in the InetSoft enterprise-specific classes.

Proxy Design Pattern

The proxy design pattern is used extensively in the design of InetSoft Enterprise products. This pattern is applied to allow the server components to support multiple communication protocols and is used in the clustering of servers for better scalability.

InetSoft Enterprise products support Java RMI communications between client and servers. The client can choose between two varieties of server: RMI and servlet (regular Java class). To the client, both servers share the same API. The details of the protocol are hidden behind the client-side proxies.

 
 

In the case of client-side proxy, the proxy serves as an API adapter and protocol handler. The client uses the base interface RepletRepository for all protocols and it is up to each proxy to implement the interface and forward the request to the appropriate server.

Another use of proxy is for transparent load balancing. There are two basic types of load balancing. Client-side load balancing makes the client choose which server to communicate with and balance the load between the servers known to the client. Server-side load balancing hides the fact that there are multiple servers from the client and transparently distributes the requests to available servers.

InetSoft Enterprise products use proxy to build transparent server-side load balancing. By using a proxy to hide the fact that there are multiple servers, the use of load balancing is transparent to the client. The server configuration can be changed without any code modification.

What Are All the Ways InetSoft Supports Scaling Up to Handle Massive Data and User Numbers?

Here are several ways in which InetSoft supports scalability:

1. Distributed Architecture:
   • InetSoft employs a distributed architecture that allows the system to scale horizontally by adding more servers or nodes. This ensures that the load is distributed across multiple machines, preventing bottlenecks and improving overall system performance.
2. Load Balancing:
   • The platform supports load balancing to evenly distribute incoming user requests across multiple servers. This helps optimize resource utilization and ensures that no single server becomes a performance bottleneck, enabling efficient handling of large user numbers.
3. In-Memory Processing:
   • InetSoft utilizes in-memory processing techniques to accelerate data retrieval and analysis. By storing frequently accessed data in memory, the platform can quickly respond to user queries, leading to faster and more scalable performance, especially when dealing with massive datasets.
4. Data Compression and Caching:
   • To optimize data transfer and reduce latency, InetSoft incorporates data compression techniques. Additionally, caching mechanisms are employed to store and reuse frequently accessed data, minimizing the need for redundant processing and enhancing system responsiveness.
5. Scalable Data Storage:
   • InetSoft is designed to integrate with scalable and high-performance data storage solutions. This ensures that the platform can handle large volumes of data efficiently and that storage can be expanded as needed to accommodate growing datasets.
6. Parallel Processing:
   • The platform supports parallel processing, allowing it to execute multiple tasks simultaneously. This is particularly beneficial for operations like data transformation, analysis, and reporting, where parallelization can significantly improve processing speed and scalability.
7. Automated Query Optimization:
   • InetSoft includes features for automated query optimization. The platform can analyze and optimize SQL queries, ensuring that database interactions are efficient, even when dealing with massive datasets and complex queries.
8. Scalable Dashboard Design:
   • InetSoft's dashboard design allows for the creation of scalable and responsive dashboards. This is essential when dealing with a large number of users accessing dashboards concurrently. The platform ensures that dashboards adapt to different screen sizes and devices for a seamless user experience.
9. Role-Based Access Control:
   • Role-based access control mechanisms are implemented to manage user permissions efficiently. This ensures that users only have access to the data and functionalities relevant to their roles, enhancing security and optimizing system performance.
10. Monitoring and Analytics:
    • InetSoft provides monitoring and analytics tools to track system performance, user interactions, and resource utilization. This allows administrators to identify potential bottlenecks, optimize configurations, and make informed decisions to further scale the system.
