This document provides an overview and comparison of SQL and NoSQL databases. It lists the most popular databases according to a Stack Overflow survey, including SQL databases like Azure SQL and NoSQL databases like Azure Cosmos DB. It then defines RDBMS and NoSQL databases and provides examples of relational and non-relational data models. The document compares features of SQL and NoSQL databases such as scalability, performance, data modeling flexibility and pricing. It also includes live demo instructions for provisioning Azure SQL and Cosmos DB databases.

SQL Types Of Databases SQL Database Managed Instance Azure SQL Elastic Database Azure Database Almost 100% compact with on- premises Database share resources (CPU, IO, Memory) Built-in high availability, Disaster Recovery, upgrade Fully Managed PaaS Good choice for heavy usage or performance peaks On-premises application can access data Full Isolation & Security 3 elastic pools service tiers (Basic, Standard, Premium) Eliminates hardware and administrative costs

- 12. SQL Management Microsoft offers Performance Dashboard, which allows the visualisation of the database performance ElasticGroups A database can be scaled up for an intensive process and scaled back after the process has completed. Security Microsoft integrates security features first in the cloud, e.g.Always Encrypted, Row-level security, Dynamic data masking, authentication, authorization, threat detection, auditing etc. Backup Automatic Backup, Restore database to point-in-time, whenTDE is enabled, backups are also encrypted. Performance Performance is measured in database DTUs (Data Transaction Units = a blended measure of CPU, Memory, I/O) Enterprise Features New features are added much faster on cloud than on premise.These features can be, Online indexing, partitioning, compression, column store indexes, in memory capabilities etc. Benefits of SQL

- 14. NoSQL Types Of Databases KEY VALUE STORE DOCUMENT COLUMN STORE GRAPH DATABASE Every record is stored as a {key} with a value. Records stored as “documents”. Key is always strings and values can be string, numeric, Boolean, arrays etc. Store and process very large amounts of data distributed over many machines Graph Databases are built with nodes, relationships between nodes and the properties of nodes Mappings are usually accompanied by cache mechanisms to maximize performance Semi-structured documents can be XML or JSON formatted Keys point to multiple columns API is typically simple Documents can be retrieved with queries AzureTables,Azure DocumentDB ->Azure CosmosDB, Hbase,Graph APIs

HighAvailability NoSQL are by design high available databases, without complexity GlobalAvailability By automatically replicating data across multiple server, this minimize latency and ensure consistent application experience. Flexible Data Modelling Developers can leverage the data types and query options that are most fit to their application. It offers a more agile development.
