2. SQL Server Architecture

SQL Server operates using a client-server architecture, where the client interacts with the server to request data and execute queries. The server is responsible for managing the database, storing data, and providing the necessary resources for queries. Here's an overview of the SQL Server architecture:

a. SQL Server Components

1. SQL Server Database Engine

   • The core service for storing, processing, and securing data.
   • Responsible for query processing, transaction management, and database management.

2. SQL Server Management Studio (SSMS)

   • A graphical user interface (GUI) for database administrators and developers to manage SQL Server instances and databases.
   • Allows users to query, configure, and monitor SQL Server databases.

3. SQL Server Agent

   • Manages scheduled tasks (jobs) like backups, indexing, and maintenance tasks.
   • Ensures automation of routine database administration tasks.

4. SQL Server Profiler

   • A tool for monitoring and capturing SQL Server activity, allowing for troubleshooting and optimization of queries.

5. Database Engine

   • Handles the storage of data on disk through various files and structures like:
     • Data Files: Store the actual data in tables and indexes.
     • Log Files: Store transaction logs for recovery purposes.

6. SQL Server Reporting Services (SSRS)

   • Provides tools for creating, managing, and delivering reports based on data in SQL Server databases.

7. SQL Server Integration Services (SSIS)

   • A tool for data integration and transformation. It's used for extracting, transforming, and loading (ETL) data from different sources into SQL Server databases.

8. SQL Server Analysis Services (SSAS)

   • A tool for creating and managing data cubes for OLAP (Online Analytical Processing) and data mining.

9. SQL Server Always On

   • A feature providing high availability and disaster recovery through techniques like Availability Groups and Failover Clustering.

---

b. SQL Server Internal Architecture

1. Memory Architecture (Buffer Pool)

   • SQL Server uses memory buffers to cache data pages in RAM for faster access. When a query is executed, the engine checks whether the requested data is in the buffer pool before reading from disk.

2. SQL Server Processes

   • SQL Server Service (sqlservr.exe): The core executable for SQL Server, responsible for managing all aspects of the database.
   • SQL Server Agent (sqlagent.exe): Manages automation tasks like jobs, alerts, and scheduling.

3. Transaction Log

   • SQL Server uses a transaction log to track all transactions and modifications to the database, ensuring ACID (Atomicity, Consistency, Isolation, Durability) properties are maintained. This log ensures recoverability in case of failure.

4. Storage Structures

   • Tables: Store data in rows and columns.
   • Indexes: Improve the speed of data retrieval.
   • Views: Virtual tables created by querying one or more tables.
   • Stored Procedures/Functions: Precompiled SQL code for frequent operations.

5. Query Processor

• SQL Server processes SQL queries through a series of steps:
1. Parse: Checks the syntax of the query.
2. Optimize: Creates an execution plan for the query.
3. Execute: Executes the query and returns the results.

Understanding Microsoft Fabric Capacity: Workspaces, Licensing, and Performance Optimization

 Fabric Capacity:

Definition: A Fabric capacity is essentially a pool of compute and storage resources to execute workloads. These capacities are required for running Microsoft Fabric features like reports, data pipelines, and notebooks.

Azure-Based Capacities: These capacities are managed under an Azure subscription. Capacities can be created via the Azure portal, offering flexibility in managing resources and costs.

Sizes: Capacities come in various sizes, from smaller capacities like F2 for experimentation to larger capacities like F64, which align with Power BI Premium features. Pricing varies by capacity size, geography, and currency.

Fabric Workspaces:

Definition: Workspaces act as logical containers where projects, workloads, and items like datasets, reports, and pipelines are organized.

Assignment to Capacity: Each workspace must be assigned to a specific capacity. Without this assignment, items in the workspace cannot execute.

Licensing Model:

Pay-As-You-Go (F License): The "pay-as-you-go" model allows you to pay for capacity usage based on consumption. This model provides flexibility, enabling you to scale resources up or down or pause capacity when not in use.

Yearly Licensing Model: This includes Power BI Premium, where capacities are pre-purchased for a fixed term. This model doesn't allow scaling or pausing but may offer cost benefits for consistent usage.

Smoothing and Bursting:

Smoothing: Ensures that workloads are distributed evenly over time to avoid spikes in capacity usage. Interactive tasks are smoothed over minutes, while large background jobs are smoothed over 24 hours.

Bursting: Allows temporary capacity increases for heavy workloads without immediate capacity resizing. This ensures critical tasks complete successfully without hitting capacity limits.

• Smoothing spreads out workloads over time to avoid capacity spikes.
• Bursting temporarily increases capacity for resource-intensive tasks to ensure they complete without hitting limits.

Storage and Additional Costs:

Storage Costs: In addition to compute, organizations are charged for storage (e.g., data lake storage costs).

User Licenses: Users require appropriate licenses:

For consuming reports: Power BI Free or Pro licenses.

For creating reports or items in Fabric: Power BI Pro licenses.
