Description: - Overview: - This content focuses on database clustering with Open Source Technologies. In particular, it shows how to set up a MySQL NDB cluster and how to implement it in a Web Application. It matches the Data Administrator role and MERLOT's Data and Information Management subdiscipline. - It includes images, links to related material and proposed exercises. - Type of Material: Tutorial - Technical Requirements: A modern web browser (such as the latest versions of Chrome, Firefox, Edge, or Safari) that supports HTML5 and JavaScript, a stable internet connection to access online content and download any necessary files, operating system compatibility with common platforms like Windows, macOS, or Linux. No special plug-ins are required to view the materials. Adequate disk space is recommended if users download example files or datasets (typically a few hundred megabytes depending on usage). Lastly, a screen resolution of at least 1024x768 pixels will be needed for optimal display of content and interface elements. - Learning Goal(s): - Explain what a database cluster is and its benefits - Recognize and gather the necessary setup requirements - Describe the basics of virtualization technology - Build and set up a Linux virtual machine - Execute relevant Linux commands - Transfer files between Windows and Linux systems - Recommended Use(s): This resource is recommended for the Databases course at ETSIINF, UPM. It can be used to complement theoretical lectures on distributed database systems and clustering by providing practical, hands-on experience in setting up and managing a MySQL NDB Cluster. The resource supports laboratory sessions where students can apply concepts learned in class, enhancing their understanding of high availability, scalability, and replication in distributed databases. It is also useful as supplementary material for students interested in deepening their knowledge of open source database technologies. - Target Student Population:This material is suitable for undergraduate and graduate students studying computer science, information technology, or related fields. It is especially useful for students enrolled in database management, distributed systems, or web development courses. The content is designed for learners with a basic understanding of databases who want to deepen their knowledge of distributed database systems and clustering techniques. - Prerequisite Knowledge: Students should have a basic understanding of relational databases, including SQL, database design, and normalization. Familiarity with the Linux operating system and basic command-line usage is also recommended. In addition, some prior knowledge of virtualization concepts and web application architecture will help students make the most of this resource. Evaluations and Observations - Quality of Content: - Strengths: - Practical and easy explanations. - Updated content with real-world examples. - Helps to reinforce Database knowledge. - Good references to external documentation (like MySql's official site). - Concerns: - There are no clear indicators of how long it might take to complete each section. - There’s no space for user feedback or questions, which could improve the learning experience. - It lacks sufficient interactive content. - Potential Effectiveness as a Teaching/Learning Tool: - Strengths: - The explanations are easy to follow. - The examples given help to see how the concepts work. - The content is well organized, including images in every step. - Concerns: - The resource could improve by adding more interactive elements to better engage students. - Some images, while helpful, are not consistently used throughout all steps, which may reduce clarity. - There is limited feedback or self-assessment opportunities for learners to check their understanding. - The resource lacks a summary or review sections that help reinforce learning. - Ease of Use: - Strengths: - Information is organized in a logical order, and each section is clearly labeled. - The step-by-step structure supports independent learning and minimizes the need for external instructions. - It includes helpful screenshots and visual cues that guide the user through technical processes. - The resource has a clean and intuitive layout, making navigation straightforward even for first-time users. - No technical issues or broken links were encountered during use. - The content is accessible without requiring additional software or complex setup. - Concerns: - There is not a help section. - The 'Objectives' section in the table of contents is empty, although the objectives are presented later in the resource.
