  Businesses today are looking for optimized data warehousing solutions to optimize their database management systems. With organizations being fully data driven now, it is always advisable to migrate databases to advanced platforms like Amazon Web Services (AWS), a cloud provider to fully get the many benefits of it. However, AWS DMS (Database Migration Service) will only be very successful and efficient if the right tools are used. These are called AWS DMS ETL tools and they help to migrate data from different sources to a single database. ETL tools largely facilitate this process.           The components of ETL tools are as follows. ·         Extract (E) – Extracting the required data from Heterogeneous or Homogeneous Data sets. ·         Transform (T) – Transforming or modifying the extracted data to match the data structures supported by the target storage database. ...

  Data security is the prime concern of organizations today, with data breaches, leaks, and hacking becoming a very common occurrence. An important method to ramp up data security is saving changed data in the database so that the historical data is always preserved. For ensuring this, various databases have introduced different solutions over time such as triggers, complex queries, timestamps, and data audits. In 2005, SQL Server introduced “after date”, “after insert”, and “after delete” features to enable SQL Server change data capture . But it did not address the issue fully and it was only in 2008 that Microsoft SQL Server launched the Change Data Capture technology where developers could capture and archive data without additional programming. CDC or Change Data Capture is the process that tracks all changes made in user-created tables. These changes are stored in relational tables for quick retrieval and access later with the T-SQL. After the features of the CDC are appl...

  Amazon Redshift database is a data warehouse solution based in the cloud. With Amazon Database Migration Service, you can migrate data from supported databases keeping Redshift as the target. However, it is essential to ensure that the AWS account and the AWS region form a part of the same Redshift cluster. The first step in DMS REDSHIFT database migration is to move data to an Amazon S3 bucket with AWS DMS. Once the files are located in the S3 bucket, the Amazon S3 automatically transfers the intended tables to the Amazon Redshift data warehouse. The S3 bucket, as pointed out previously has to be in the same AWS Region as the Amazon Redshift database. However, when AWS CLI or DMS API is used for DMS Redshift migration, an AWS Identity and Access Management (IAM) path have to be set up to get access to S3. Amazon Redshift provides automated processes in the following cases. ·         Modifications made at source tables by incremental dat...

  AWS (Amazon Web Services) is one of the biggest cloud platforms in the world.   Customers range from large corporations to small businesses and startups, all aiming to become more efficient, innovative, and agile at low costs. Because of the new technology and speed that AWS brings to the table, there is a growing trend to migrate on-premises databases and systems to the AWS platform using the best AWS data migration tool . There are several types of cloud migration. One is to move data and applications from a local on-premises database to a cloud platform and another is to migrate the same from one cloud platform to another, better known as cloud to cloud migration.   There are several benefits of migrating to AWS. It provides separate computing and storage facilities with flexibility in usage. Users can scale up or down in either of them by paying only for the quantum of resources used. This pay model is one of the unique features of AWS. Further, even when multip...

  Change Data Capture (CDC) is the process that identifies and captures the changes made to the last refreshed data or metadata with periodicity fixed at minutes or even seconds. The changes made are entered in a separate data repository by specific software. Similar to batch loads, CDC ensures that the replication software copies one source to several targets. AWS DMS is a cloud-based service that facilitates easy migration of relational databases, data warehouses, NoSQL databases through AWS DMS CDC . It can also be used for migrating data to the AWS cloud or on-premises setup or a combination of both. Since AWS DMS is a component of the AWS cloud, it has all the features of AWS cloud services like cost efficiency, speed to market, security, and flexibility. An AWS DMS CDC can be created for capturing current changes to the source data during the replication process. Regardless of whether the work is a CDC-only task or a full-load one the migration process has tables only fr...

  Amazon Web Services (AWS) is the most comprehensive cloud platform in the world. There are over 175 fully-featured data centers globally and millions of customers ranging from large enterprises to small centers, all looking to become more agile, innovate faster, and lower costs. It is for these reasons that businesses are today opting for AWS data migration from on-premises databases and systems. There are various types of cloud migration of which the most common is transferring data and applications from a local on-premises database to a public cloud. Another is moving databases and applications from one cloud platform to another known as a cloud to cloud migration. Finally, there is the reverse migration which is rare but involves moving data and applications away from the cloud to on-premises. There are several benefits of AWS data migration . The main reason is to ensure greater data management flexibility, access to a pay-per-use model, and data redundancy. Another adv...

  Data replication software quickly creates a replica of the original database at a location that is not linked to the source of the primary data. Data security, disaster recovery and resolution, and business continuity are thereby assured. In the event of an outage, users can fall back on the secondary databases, and once the problem is resolved revert back to the primary database which is auto-updated for all changes.    Replicating software provides centralized data management and replication policy across a diverse range of data targets and sources. This process is different from backups which retain a copy of the data for an extended period of time. Replicating software frequently updates modified data so that the central database and all those at other locations are always brought up to date. Data replication software has multiple benefits. It makes sure that data consistency is maintained for end-users who in the usual course of business have to access mult...
