Oracle Vs Teradata: 6 Critical Differences

In Today’s data-driven modern world, competition between companies is prevalent when they offer similar products. In a competitive market, providing the best services and products and having the majority of customers for a particular product does help shape a company’s profit. When it comes to Database Management, the choice of Oracle vs Teradata is a relatively tough one.

In this article, we compared two databases that may help you decide which to choose for your business operations. We have also listed a few parameters to distinguish them.

What is Teradata?

Teradata is an open-source Relational Database Management System (RDBMS) managed and owned by Teradata Corp. Teradata architecture is built around Massive Parallel Processing, and hence it is widely used for creating large-scale data warehousing applications. Teradata is a massively open processing system that supports Unix/Linux/Windows server platforms.

Oracle vs Teradata 

Teradata and Oracle are both RDBMS systems and support ANSI SQL to interact with the data. Both Teradata and Oracle have lots of similarities, but they also have some differences. Below is a list of key differences between Teradata and Oracle:

1) Oracle vs Teradata: Architecture

Teradata 

Teradata architecture is based on Massive Parallel Processing, which acts as a single data source that can process concurrent requests from multiple client applications parallelly. Following are the components of Teradata architecture.

• Node: This is the basic unit of Teradata that comprises the Operating system, CPU, memory, disk space, and many more.
• Parsing Engine: Parsing Engine is responsible for receiving the query from clients, checking syntax errors, and checking objects. The parsing engine is responsible for receiving queries from clients and preparing an execution plan. 
• Message Parsing Layer: The Message Parsing Layer is known as BYNET and is the networking layer in Teradata that allows communication between Parsing Engine and Access Module Processor. 
• Access Module Processor (AMP): AMP is the virtual processor, and it is used to store and retrieve data. It receives the data execution plan from Parsing Engine, performs data type conversions, and stores the data in the disk.

The architecture of Teradata is shown below.

Oracle

Oracle is a popular RDBMS data storage system. A basic OracleDB consists of an Oracle database and database instance. It typically contains memory structure, process structure, and storage structure.

2) Oracle vs Teradata: Mode of Operation

Teradata

Teradata is a Relational Model with Shared nothing architecture. In Teradata, the hardware and software need to be installed on-premise for optimal performance. Thus the implementation of big data depends upon the machine capability. 

Oracle

Oracle has an Object-Relational Model and has shared everything architecture. Oracle also needs the hardware and software to be installed on-premise for optimal performance. However, when it comes to big data, Oracle’s performance is lower than Teradata’s.

3) Oracle vs Teradata: Size and Capacity

Teradata

Teradata usually operates in fixed size and capacity; you need to purchase the license and upgrade the hardware by restructuring it for any additional capacity.

Oracle

OracleDB offers four sockets in its standard edition that can be used for scalability, but you need to jump to the enterprise edition with the higher workload. 

4) Oracle vs Teradata: APIs and Other Access Methods

Teradata

Teradata has good support for various API methods: NET CLient API, HTTP Rest, JDBC, and many more. 

Oracle

Oracle also has a good number of API support ranging from ODP.net, ODBC, JDBC, etc.

5) Oracle vs Teradata: Programming Languages

Teradata

Teradata supports various programming languages like C, C++, Java, Cobol, Perl, Python, R, and many more.

Oracle

Oracle also supports various programming languages like – C, C++, Java, COBOL, PL/SQL, and Visual Basic.

6) Oracle vs Teradata: Pricing

Teradata

Teradata comes with Teradata Vantage with AWS support, which provides a reliable, secure, and scalable single-tenant environment with AWS as cloud infrastructure. The pricing model follows Pay-as-per-Go.

Oracle 

Oracle Cloud provides a Free Tier with no time limits to some essential services like Compute and Storage. For more detail on cloud pricing.

Conclusion

Both Teradata and Oracle are best in their way. However, Teradata seems to gain much popularity due to its excellent performance on the big data side.

Choosing a database purely depends on the business requirements and other factors such as organization structure, financial models, business types, etc. In this blog post, we have compared Teradata and Oracle, both Relational Database Management System, and outrun each other differently.
