Unlike SQL and Oracle, which have in-built replication capabilities, we don't have similar functionality with Teradata.

Philemon Olusegun - PeerSpot reviewer
Qhse Manager at a outsourcing company with 10,001+ employees
Reliable backups and high-capacity data management have transformed large-scale census projects
When it comes to how Oracle Database can be improved, for me it is all about training and development in terms of gamification, creating awareness, and spreading the word to aspiring database administrators and database developers. As I have used it in the past and in recent times, many people are trying to get into IT, so the opportunity exists. Oracle has the market opportunity to take this time to spread its offerings and ensure that many aspiring professionals are aware of its services and products. From my perspective, there is not much to add regarding the needed improvements for the interface and the documentation. I give it a nine because I think Oracle sometimes can make things complicated. You have many services, many products, and many tools for different use cases. So it is difficult for someone who is only used to a particular product, such as Oracle Database, to understand all the other products and services that it provides. Probably streamlining it and making it available with categorized use cases for specific job roles would help. If you are a database developer, these are the tools that you need to be familiar with in Oracle's suite of products, and if you are a database administrator, these are the tools. Categorizing them based on the job role or function of people who are accessing these products and providing training capabilities on how to use them and how these products interchange and talk to each other would be very important because that is one of the things I struggled with when I started my journey as an Oracle Database administrator. Having that visibility of all the software products and providing free training and documentation on how you can improve and which products are best suited for integration to your product from Oracle would go a long way to help organizations and professionals. Regarding Oracle Database's AI capabilities, I am very keen on its governance and security. I think more work needs to be done on the security and ensuring that the database for a large number of people is watertight. AI is here to stay; however, governance and more stress testing of the AI capabilities needs to be done to ensure there is no breach of data. I would rate it currently at 6 over 10 and there is room for improvement. As long as there are government policies and Oracle policies that can mitigate any breaches of data and serious security issues, releasing people's records over the internet, there is always room for improvement in that regard.

Delivers consistent performance and enables advanced analytics across complex data environments
Teradata stands out as a solid platform for managing and analyzing large volumes of data. Its architecture allows information to be processed efficiently while maintaining stable performance, even in highly demanding environments. One of its most notable strengths is the ability to run complex queries at high speed, which is essential for organizations that require timely and reliable analytics. Teradata offers a well-integrated ecosystem that supports working with different types of data and enables scalability as organizational needs grow. Its focus on advanced analytics, integration with modern business intelligence tools, and the ability to operate both on-premise and in the cloud make it a versatile solution for data warehousing and large-scale processing. Teradata's stability, technological maturity, and the availability of strong documentation and best practices are noteworthy. I consider Teradata to be a tool with great potential for any organization looking to enhance its analytical capabilities, optimize data processing, and move toward more data-driven decision-making. Teradata stands out as a solid platform for managing a large volume of data in different projects. Its architecture allows information to be processed efficiently while maintaining stable performance, even in high-demanding environments. A well-integrated AI ecosystem that supports working with different types of data and enables scalability as organizational needs grow across different kinds of enterprises or organizations. The focus on advanced analytics integration with modern business intelligence tools is particularly valuable. Teradata combines a powerful parallel process and optimizing SQL engine with a highly scalable architecture allowing businesses to execute complex queries and analytics in real-time. It supports multi-cloud, hybrid, and on-premise environments, giving organizations flexibility to choose the setup that best aligns with their strategy. One of the biggest strengths is the ability to unify disparate data sources and support high concurrency, enabling different teams, such as analytics, operations, BI, and data science, to access consistent, trusted data across the enterprise.
