Which of the following services is designed for storage, automatic indexing, and rapid querying of json documents that are commonly found in nosql applications?

Azure Cosmos DB vs Azure Storage: What are the differences? Azure Cosmos DB and Azure Storage are cloud-based storage services. They differ in terms of their data models, scalability, querying capabilities, and storage options. Here are the key differences between them: • Data Model: Azure Cosmos DB is a globally distributed, multi-model database service that supports various data models, including key-value, document, columnar, and graph. Azure Storage, on the other hand, primarily offers a simple object storage service with a key-value data model. It is designed for storing unstructured data such as blobs, files, queues, and tables. • Scalability: Azure Cosmos DB is built for global scalability and can automatically scale throughput and storage across multiple regions. It offers elastic scalability with fine-grained control over performance and cost. Azure Storage also provides scalability, but it requires manual configuration and management of storage accounts and blob containers to handle increased load. Scaling Azure Storage may involve sharding data across multiple storage accounts. • Querying Capabilities: Azure Cosmos DB supports rich query capabilities across various data models. It provides a SQL-like query language called SQL API for querying JSON documents. It also supports other APIs like Gremlin for graph data and MongoDB API for document-oriented querying. Azure Storage, on the other hand, does not offer built-in query capabilities. Retrieving data from Azur...

NoSQL is a type of database management system (DBMS) that is designed to handle and store large volumes of unstructured and semi-structured data. Unlike traditional relational databases that use tables with pre-defined schemas to store data, NoSQL databases use flexible data models that can adapt to changes in data structures and are capable of scaling horizontally to handle growing amounts of data. The term NoSQL originally referred to “non-SQL” or “non-relational” databases, but the term has since evolved to mean “not only SQL,” as NoSQL databases have expanded to include a wide range of different database architectures and data models. NoSQL databases are generally classified into four main categories: • Document databases: These databases store data as semi-structured documents, such as JSON or XML, and can be queried using document-oriented query languages. • Key-value stores: These databases store data as key-value pairs, and are optimized for simple and fast read/write operations. • Column-family stores: These databases store data as column families, which are sets of columns that are treated as a single entity. They are optimized for fast and efficient querying of large amounts of data. • Graph databases: These databases store data as nodes and edges, and are designed to handle complex relationships between data. NoSQL databases are often used in applications where there is a high volume of data that needs to be processed and analyzed in real-time, such as social m...

Relational and NoSQL are two types of database systems commonly implemented in cloud-native apps. They're built differently, store data differently, and accessed differently. In this section, we'll look at both. Later in this chapter, we'll look at an emerging database technology called NewSQL. Relational databases have been a prevalent technology for decades. They're mature, proven, and widely implemented. Competing database products, tooling, and expertise abound. Relational databases provide a store of related data tables. These tables have a fixed schema, use SQL (Structured Query Language) to manage data, and support ACID guarantees. No-SQL databases refer to high-performance, non-relational data stores. They excel in their ease-of-use, scalability, resilience, and availability characteristics. Instead of joining tables of normalized data, NoSQL stores unstructured or semi-structured data, often in key-value pairs or JSON documents. No-SQL databases typically don't provide ACID guarantees beyond the scope of a single database partition. High volume services that require sub second response time favor NoSQL datastores. The impact of NoSQL databases include several different models for accessing and managing data, each suited to specific use cases. Figure 5-9 presents four common models. Figure 5-9: Data models for NoSQL databases Model Characteristics Document Store Data and metadata are stored hierarchically in JSON-based documents inside the database. Key Value Store...

A non-relational database is a database that does not use the tabular schema of rows and columns found in most traditional database systems. Instead, non-relational databases use a storage model that is optimized for the specific requirements of the type of data being stored. For example, data may be stored as simple key/value pairs, as JSON documents, or as a graph consisting of edges and vertices. What all of these data stores have in common is that they don't use a The term NoSQL refers to data stores that do not use SQL for queries. Instead, the data stores use other programming languages and constructs to query the data. In practice, "NoSQL" means "non-relational database," even though many of these databases do support SQL-compatible queries. However, the underlying query execution strategy is usually very different from the way a traditional RDBMS would execute the same SQL query. The following sections describe the major categories of non-relational or NoSQL database. Document data stores A document data store manages a set of named string fields and object data values in an entity that's referred to as a document. These data stores typically store data in the form of JSON documents. Each field value could be a scalar item, such as a number, or a compound element, such as a list or a parent-child collection. The data in the fields of a document can be encoded in various ways, including XML, YAML, JSON, BSON, or even stored as plain text. The fields within documents...

NoSQL databases are interchangeably referred to as “nonrelational,” “NoSQL DBs,” or “non-SQL” to highlight the fact that they can handle huge volumes of rapidly changing, unstructured data in different ways than a relational (SQL) database with rows and tables. NoSQL technologies have been around since the 1960s, under various names, but are enjoying a surge in popularity as the data landscape shifts and developers need to adapt to handle the sheer volume and vast array of data generated from the cloud, mobile, social media, and big data. From viral celebrity tweets to life-saving information in electronic medical records, new data and data types are being generated at a dizzying pace. NoSQL databases have evolved to help developers quickly create database systems to store the new information and make it readily available for search, consolidation, and analysis. NoSQL databases help IT pros and developers manage the new challenges of ever-expanding diversity of data types and models and are highly effective at handling unpredictable data, often with blazing-fast query speeds. They also provide a smooth database migration to the cloud for existing NoSQL workloads. • Handling data that is relational and has logical and discrete requirements that can be identified in advance. • Schema that must be maintained and kept in sync between the app and database. • Legacy systems built for relational structures. • Apps requiring complex querying or multi-row transactions. Many NoSQL d...
