海外TECH	DEV Community	AWS Database Services Fundamentals	https://dev.to/aws-builders/aws-database-services-fundamentals-4ml6	AWS Database Services FundamentalsA database is a collection of information that is organized in a way that can be easily accessed managed and updated Computer databases often contain record sets or data files which contain information about sales transactions or interactions with specific customers Databases are important back end systems used to store manage update and analyze data for all types of applications from small back office systems to consumer and mobile web applications on a global scale Most databases use structured query language SQL to write and query data Databases have evolved dramatically since their inception in the early s Navigation databases such as the hierarchical database which was based on a tree like model and only allowed a one to many relationship and the network database a more flexible model that allowed multiple relationships were the original systems used to store and manipulate data Although simple these early systems were inflexible In the s relational databases became popular followed by object oriented databases in the s More recently NoSQL databases emergedin response to the growth of the internet and the need for greater speed and processing of unstructured data Today the cloud database and separate databases are opening up new ways as to how to collect store manage and use the data According to their type the databases can be classified as relational and non relational databases Relational databases became popular in the eighties the elements of a relational database are organized as a set of tables with columns and rows Relational database technology provides the most efficient and flexible way to access structured information NoSQL or non relational databases allow unstructured and semi structured data to be stored and manipulated unlike a relational database which defines how all the data inserted into the database should be composed NoSQL databases became popular as web applications became more common and complex The databases can also be classified according to their type of workload into operational databases OLTP Online Transaction Processing or analytical databases OLAP Online Analytical Processing OLTP systems are databases oriented to transaction processing A transaction generates an atomic process which must be validated with a commit or invalidated with a rollback and that may involve data insertion modification and deletion operations The transactional process is typical of operational databases OLAP systems are databases oriented to analytical processing This analysis usually involves generally the reading of large amounts of data to get to extract some type of useful information that is helpful for decision making such as sales trends consumer behavior patterns elaboration of complex reports etc AWS offers a wide variety of custom databases for your specific application use cases Our fully managed database services include relational databases for transactional applications non relational databases for Internet scale applications a data warehouse for analytics an in memory database for caching and workloads in real time and a graphs database to create applications with strongly connected data With AWS Database Migration Service migrating existing databases to AWS is easy and cost effective AWS Databases were designed from the ground up to support the scale performance and availability demands of modern globally distributed applications with microservices architectures AWS offers database engines and continues to grow including relational and non relational types for every application need The types of AWS databases are described below RelationalDescription Relational databases store data with predefined schemas and relationships between them These databases are designed to support ACID transactions and maintain referential integrity and strong data consistency Use cases Aplicaciones tradicionales ERP CRM y e commerceAWS service Amazon Aurora Amazon RDS Amazon RedshiftKey valueDescription Key value databases are optimized for common access patterns typically to store and retrieve large volumes of data These databases deliver quick response times even in extreme volumes of concurrent requests Use cases High traffic web apps e commerce systems gaming applicationsAWS service Amazon DynamoDBIn memoryDescription In memory databases are used for applications that require real time access to data By storing data directly in memory these databases deliver microsecond latency to applications for whom millisecond latency is not enough Use cases Caching session management gaming leaderboards geospatial applicationsAWS service Amazon ElastiCache for Memcached Amazon ElastiCache for Redis Amazon MemoryDB for RedisDocumentDescription A document database is designed to store semistructured data as JSON like documents These databases help developers build and update applications quickly Use cases Content management catalogs user profilesAWS service Amazon DocumentDB with MongoDB compatibility Wide columnDescription A wide column store is a type of NoSQL database It uses tables rows and columns but unlike a relational database the names and format of the columns can vary from row to row in the same table Use cases High scale industrial apps for equipment maintenance fleet management and route optimizationAWS service Amazon Keyspaces for Apache Cassandra GraphDescription Graph databases are for applications that need to navigate and query millions of relationships between highly connected graph datasets with millisecond latency at large scale Use cases Fraud detection social networking recommendation enginesAWS service Amazon NeptuneTime seriesDescription Time series databases efficiently collect synthesize and derive insights from data that changes over time and with queries spanning time intervals Use cases IoT applications DevOps industrial telemetryAWS service Amazon TimestreamLedgerDescription Systems of record supply chain registrations banking transactionsUse cases Systems of record supply chain registrations banking transactionsAWS service Amazon QLDBStrategy for selecting a databaseThe optimal database solution for a system varies depending on the requirements for availability consistency partition tolerance latency durability scalability and query capacity Many systems use different database solutions for various subsystems and allow different features to improve performance Selecting the wrong database features and solutions can result in lower performance efficiencies When selecting a database service consider the dimensions and choose the one that best suits each of your requirements and components of your application and architecture AWS Leader in Gartner s New Magic QuadrantLIndustry analyst firm Gartner has published a new report the Magic Quadrant for Cloud Database Management Systems naming AWS as a Leader and placing AWS highest among the vendors evaluated for “Ability to Execute This report is
