Course Overview
Course Title: Database Administration 361 (DBA361)
Institution: Belgium Campus, iTversity
Session Year: 2021
Objectives
By the end of this course, students will understand key topics including SQL Server technology overview, prerequisites and preinstallation steps, SQL Server installation process, patching, post-installation configuration, monitoring toolset, and relational database systems.
Relational Database Systems
The relational data model is implemented via a Relational Database Management System (RDBMS). A data model encompasses concepts, relations, and constraints that represent real-world data, with the central element being a 'relation', which translates to a 'table' from the user's perspective. An RDBMS simplifies the understanding and implementation of relational data models, with examples including Microsoft SQL Server, Oracle, MySQL, and IBM's DB2. Modern RDBMSs manage data, enforce constraints, and facilitate data retrieval.
Required Features of a Database System
Essential features of a database system include user interfaces that enable users to create, retrieve, and modify databases; data independence which offers both physical and logical independence from data structures; query optimization for efficient data querying strategies; data integrity to validate data consistency; concurrency control to manage simultaneous data updates; backup and recovery to ensure data safety and recoverability; and database security to protect data from unauthorized access.
Comparison of SQL Server Editions
Understanding different SQL Server editions is critical for selecting the suitable one for your environment. The Enterprise Edition provides high performance for critical applications, while the Standard Edition offers full database capabilities with resource limitations. The Developer Edition includes enterprise features for development purposes exclusively, and the Express Edition is free but with limited functionality for smaller applications. The Express Edition imposes limits such as a 10GB database size, 1GB RAM, and 1 CPU socket/four cores.
License Models
SQL Server 2022 has two primary licensing options: Per Core Licensing, which requires licenses for each core utilized, and Server + CAL Licensing, needing a server license along with CALs for users/devices. Per Core is more suitable for high-performance requirements, as it eliminates the need for CALs.
SQL Server Technology Overview
Microsoft SQL Server is a comprehensive technology suite for data management, analysis, and visualization. It serves as a robust end-to-end data processing platform, with the Database Engine as its core relational database system, responsible for handling recovery, transactions, and security management. The architecture of the Database Engine comprises SQLOS, the Storage Engine, and the Relational Engine, providing secure and optimized access to relational data.
SQL Server Integration Services (SSIS)
SSIS acts as the data pump for SQL Server, facilitating data movement between various sources, and is commonly employed for data warehousing using ETL processes. Control Flow tasks are essential components of SSIS packages.
SQL Server Analysis Services (SSAS)
SSAS converts relational data into multi-dimensional storage to enable efficient analysis and supports both Multidimensional and Tabular modes to cater to different analysis needs.
SQL Server Reporting Services (SSRS)
SSRS provides visualization of data from various sources, offering centralized reporting capabilities, and supports management through HTTP/HTTPS endpoints.
Machine Learning Services
Machine Learning Services allow for predictive analytics using R and Python, which can be installed directly in SQL Server or on a separate ML server.
SQL Server Agent
SQL Server Agent automates and monitors scheduled tasks and jobs, which are vital for maintenance and data management, though it is not enabled by default in SQL Server Express Edition.
Operating System Support
Starting from SQL Server 2017, it supports operation on Linux and Docker containers, with installation guided by a System Configuration Checker to ensure compatibility and the fulfillment of prerequisites.
