Interview Questions for M3P System Operation

The M3P system architecture is typically a three-tiered client-server model, though the specific implementation can vary depending on the vendor and configuration. It comprises a presentation tier (the user interface), an application tier (the business logic and data processing), and a data tier (where the data is stored).

• Presentation Tier: This is where users interact with the system, usually through a web-based interface or a dedicated client application. It handles user input, displays results, and manages the user experience.
• Application Tier: This layer is responsible for processing user requests, executing business rules, and interacting with the database. It acts as an intermediary between the presentation tier and the data tier, ensuring data integrity and consistency. This often involves middleware and application servers.
• Data Tier: This layer houses the system’s databases, typically relational databases like Oracle or SQL Server. It’s responsible for storing, retrieving, and managing all the system’s data. Robust database management systems are critical for performance and data security.

Think of it like a restaurant: the presentation tier is the waiter taking your order, the application tier is the kitchen preparing the food, and the data tier is the storage room holding the ingredients.

My experience with M3P system troubleshooting involves a systematic approach. I start by gathering information: checking logs, reviewing system monitoring tools, and interviewing users to understand the nature of the problem. Then, I isolate the problem by systematically eliminating potential causes.
