These professionals use various Azure data services and languages to store and produce cleansed and enhanced datasets for analysis.This course covers, how to provisioning data storage services like Azure SQL, Storage account, Data lakes. In the Azure Data factory section, we cover how to transform your data, identifying performance bottlenecks, and accessing external data sources including on-premise SQL server and file systems.Azure Data Factory (ADF):The Azure Data Factory service is a fully managed service for composing data storage, processing, and movement services into streamlined, scalable, and reliable data production pipelines. The Azure Data Factory (ADF) is a service designed to allow developers to integrate disparate data sources. ADF or Azure Data Factory is a platform somewhat like SSIS or Alteryx in the Azure environment to manage the data you have both on-prem and in the cloud.It provides access to on-premises data with the help of a software. By using this link we could connect to the on-premise file system as well as to on-premise SQL databases. From Azure Data Factory, you could access almost all azure services without any difficulties. Access to on-premises data is provided through a data management gateway that connects to on-premises SQL Server databases and we will show you how to install this software and how to connect your on-premises environment with Azure cloud.If you ever created any data transfer activities in Azure, or in SSIS, you will find it a similar tool. If you use ADF, you could focus on your data-the serverless integration service does the rest.Topics In Azure Data Factory: Append Variable ActivityExecute Pipeline activityForEach activityGet Metadata activityIf Condition activityLookup activitySet variable activityUntil activityValidation activityData Flow activityMapping data flowAggregate transformation.Alter row transformation.Conditional split transformation.Derived column transformation.Exists transformation.Join transformation.Lookup transformation.The new branch mapping data flow transformation.Select transformation.Sink transformation.Source transformation.Azure Data Factory union transformation.ParameterizingTrigger In Azure Data Factory.Manual Trigger.Scheduled Trigger.Tumbling window Event Trigger.Dynamic Data processing And Pipeline Execution Based on External Event. and many more (with real-life scenarios). Check out our course descriptions for updated information.SQL Database -Cloud Database as a Service:Azure SQL Database is a fully managed relational database with built-in intelligence supporting self-driving features such as performance tuning and threat alerts. According to Wiki, Microsoft Azure SQL Database is a managed cloud database provided as part of Microsoft Azure. A cloud database is a database that runs on a cloud computing platform, and access to it is provided as a service. Managed database services take care of scalability, backup, and high availability of the database.Azure SQL Database: Azure SQL Database is a relational database-as-a-service (DBaaS) based on the latest stable version of Microsoft SQL Server. It is a fully managed Platform as a Service (PaaS) Database Engine that handles most of the database management functions such as upgrading, patching, backups, and monitoring without user involvement. In this course, we will show you how to launch the Azure SQL database in five minutes, with and without sample data. We will show you, how to use SQL elastic pools. Elastic pools help you manage and scale multiple Azure SQL databases. According to Azure documentation, SQL Database elastic pools are a simple, cost-effective solution for managing and scaling multiple databases that have varying and unpredictable usage demands. With an elastic pool, you determine the amount of resources that the elastic pool requires to handle the workload of its databases, and the amount of resources for each pooled database.Azure SQL Database is always running on the latest stable version of the SQL Server Database Engine and patched OS with 99.99% availability.The databases in an elastic pool are on a single Azure SQL Database server and share a set number of resources at a set price. By the end of this course, you will have a clear idea about how to configure SQL elastic pool.Geo-Replication: Active geo-replication is an Azure SQL Database feature that allows you to create readable secondary databases of individual databases on a SQL Database server in the same or different data center (region). We will show you how you could configure a Geo-replication and force failover to the secondary database manually.Azure Cosmos DB:Azure Cosmos DB is Microsoft's globally distributed, multi-model database service. With a click of a button, Cosmos DB enables you to elastically and independently scale throughput and storage across any number of Azure regions worldwide. In our course, we will see.How you could create a cosmos DB account, How to Create Databases inside your cosmosDB accountHow to insert data into CosmsoDB containers.How to Restive data that you saved in cosmos DB tables or containers by using SQLIntroduction to Azure Storage:Azure Storage is Microsoft's cloud storage solution for modern data storage scenarios. Azure Storage offers a massively scalable object store for data objects, a file system service for the cloud, a messaging store for reliable messaging, and a NoSQL store.In this course, we will cover how to create a storage account, how to create containers and file systems and how to upload data into these services and how to access these storage services from different azure data solutions services like data factory, data bricks, and SQL databases. Azure Data Lake Storage:Azure Data Lake Storage, is a fully-managed, elastic, scalable, and secure file system that supports HDFS semantics and works with the Hadoop ecosystem.
