Oracle is a relational database management system of the Oracle Corporation and has been mainly designed for grid computing and data warehousing. For decades now, it has offered affordable solutions for applications and data management activities. However, the recent advancements in cloud technologies have made most businesses want to migrate databases from Oracle to Snowflake, a cloud-based data warehousing solution. What does a cloud platform bring to the table that makes Oracle users want to migrate to snowflake? Here are some of the main reasons for doing so. · Snowflake provides excellent data management solutions as users can work with both structured and unstructured data, an attribute that is not available in the Oracle database. · Since Snowflake is a SaaS product, it provides unlimited storage facilities, enabling businesses to meet a sudden spike in demand for storage resources without investing in additional infrastructure. · Similarly, Snowflake offer...

Amazon S3 (Simple Storage Service) is a cloud-based data storage service that facilitates data storage in native form – unstructured, semi-structured, or structured. Data is stored in a secure environment with data durability as high as 99.999999999 (11 9s). Data in S3 is stored in buckets with files consisting of metadata and objects. An object has to be uploaded to Amazon S3 for storing a file or metadata in a bucket. Once done, permissions can be set on the object or the related metadata stored in the buckets for holding the objects. Access to the buckets is restricted to those who have the required permissions to access logs and objects for deciding where they will be stored on Amazon S3. The Concept of Amazon S3 Data Lake Several competencies are used when building an S3 data lake such as Machine Learning (ML), Artificial Intelligence (AI), big data analytics, media data processing applications, and high-performance computing (HPC). All these together help to get critical busines...

The Database Migration Service (DMS) of Amazon Web Service (AWS) is a cloud-based platform that facilitates the migration of databases from on-premises systems to the cloud or from one cloud provider to another. For   AWS DMS   to function optimally, one of the sources or the target, or both should be functioning in a cloud environment. The Database Migration Service is very user-friendly. First, it is compatible with the most commonly used databases. Next, DMS allows continuous data replication, and several databases can be easily consolidated into a petabyte-sized data warehouse through data streaming to Amazon Simple Storage Service (S3) or Amazon Redshift. A very important advantage of working with AWS DMSis that the source database remains fully functional during the migration process. This is a great benefit for large data-driven organizations for whom downtime even for brief periods can upset operating schedules. Some of the other cutting-edge benefits of AWS DMS are as...

Data lakes are storage repositories of data where massive volumes can be stored in one place for later processing and analytics. In the past, data storage capabilities consisted of several components like data warehouses, data marts, and more which are now not required due to technological advancements and databases being operated in the cloud. One of the most highly optimized cloud-based data warehousing solutions providing unlimited storage and computing facilities is the Snowflake data lake . Users can scale up or down in data usage for computing or storing, paying for the resources used only. This is critical for businesses as they do not have to invest in additional hardware or software when faced with a sudden surge in demand.      Data Structure of the Snowflake Data Lake Snowflake Data Lake has an extendable architecture that ensures seamless loading of databases within the same cloud environment, thereby doing away with the need to choose a specific data warehous...

This post will go into migrating databases from Oracle to S3 and analyze the benefits of moving to the Amazon Web Service (AWS) S3 (Simple Storage Service). Oracle, a proprietary relational database management system (RDMS) is mainly used for data warehousing and Online Transaction Processing (OLTP). It provides support to GNU/LINUX and Windows Server and most applications merge seamlessly into the database. Being ACID-compliant, Oracle assures data integrity and reliability. On the other hand, Amazon S3 is a data warehousing solution based in the cloud and is ideal for Online Analytical Processing (OLAP). For launching applications, an S3 cluster is initiated through API calls and then connected with the help of the AWS Management Console to an S3 instance. The benefits of S3 range from high data availability, scalability, and performance, to unlimited storage. It is because of these advantages that organizations prefer to move databases fro m Oracle to S3. Further, S3 can backup, re...

Before going into the details of migrating databases from Microsoft SQL Server to Snowflake – the tools and the processes – it is necessary to understand the benefits of Snowflake. Why do organizations today prefer SQL Server to Snowflake migration of databases? First, Snowflake, an optimized cloud-based data warehousing solution enables the migration of data in its native format regardless of whether it is unstructured, semi-structured, or structured. This feature is not available in other leading database platforms like Oracle and SQL Server. Snowflake also has high computing abilities and multiple users can simultaneously execute several intricate queries without any lag or drop in performance. Further, Snowflake offers unlimited storage space and users can download it in minutes whenever required by paying for the quantum of resources used. This leads to huge savings when compared with traditional database systems that charged flat fees for storage space regardless of the volumes ...
