Non-Relational Data in Azure Flashcards
Microsoft Azure Data Fundamentals DP-900 Flashcards
| Front | Back |
| Advantages of graph storage for relationship data | Graph storage enables quick traversal of complex relationships with nodes and edges. |
| Azure Table Storage | A cost-effective key-value storage solution optimized for large-scale structured data. |
| Benefits of document storage for semi-structured data | Document storage allows easy handling of JSON, BSON, or XML data with flexible schemas. |
| Define eventual consistency | Eventual consistency ensures that all copies of data will become consistent over time, without requiring immediate consistency. |
| Define NoSQL | NoSQL refers to non-relational databases designed to handle a wide variety of data structures like key-value, document, column-family, and graph models. |
| Explain polyglot persistence | The practice of using different types of databases depending on specific workload requirements. |
| Explain the term "multi-model database" | A multi-model database supports multiple types of data models and query languages. |
| How does Azure Cosmos DB ensure high availability | Azure Cosmos DB provides automatic replication and multi-region failover capabilities. |
| How does Azure Cosmos DB support multiple data models | Azure Cosmos DB natively supports key-value, document, column-family, and graph data models in a unified platform. |
| Key benefit of NoSQL databases | NoSQL databases provide flexible schemas to scale horizontally and efficiently manage large or unstructured datasets. |
| List the main non-relational database models | Key-value, Document, Column-family, and Graph. |
| What does horizontal scaling in NoSQL mean | Horizontal scaling involves adding more servers to handle increased data or traffic, rather than upgrading an existing server. |
| What is a partition key in Azure Cosmos DB | A partition key helps distribute data across multiple physical partitions to optimize performance and scalability. |
| What is Azure Cosmos DB | Azure Cosmos DB is a globally distributed multi-model database service for managing non-relational data. |
| What is column-family storage | A NoSQL database that organizes data into rows and columns, grouped by families for efficient querying. |
| What is document storage | Document storage is a NoSQL database that stores data in semi-structured formats like JSON or XML documents. |
| What is graph storage | Graph storage is a database designed to store and navigate relationships between data points using nodes and edges. |
| What is key-value storage | Key-value storage is a type of NoSQL database where data is stored as key-value pairs. |
| What kind of consistency levels does Azure Cosmos DB offer | Azure Cosmos DB offers five consistency levels: Strong, Bounded Staleness, Session, Consistent Prefix, and Eventual. |
| What type of data is ideal for column-family storage | Analytics and data warehousing workloads benefit from column-family storage due to efficient queries over large datasets. |
This deck covers non-relational databases, such as Azure Cosmos DB, NoSQL, and key-value, graph, or document storage options.
