The components included in the Teradata database system to support data communication management are:. By: Justin Stoltzfus Contributor, Reviewer. By: Satish Balakrishnan. Dictionary Dictionary Term of the Day.
Natural Language Processing. Techopedia Terms. Connect with us. Sign up. Term of the Day. An increased number of nodes improves overall system performance. Unlimited parallelism: This feature enables huge tasks to be divided into smaller tasks.
One can run these tasks in a parallel manner. Mature optimizer: Teradata has an advanced optimizer that can support many joins in one query. This is because of the easy setup, administration, and maintenance.
These utilities enable users to import or export data from or to the Teradata system. Connectivity: Teradata system allows connectivity with other systems such as mainframes and network-attached systems. Load and unload utilities: It consists of load utilities that can carry data into the Teradata system. It also consists of unload utilities that carry data out of the system. Shared nothing architecture: This database consists of a shared-nothing architecture where disks, Teradata nodes, and AMPs Access Module Processors are independent.
This does not allow the sharing of resources, which optimizes performance in a given task. The architecture of Teradata The following diagram shows the architecture of Teradata. Storage architecture This architecture is used when the client makes a storage query. Image Source: JavatPoint Parsing engine The following are the specific roles of a parsing engine in the storage architecture: It receives the queries SQL made by clients.
It checks the queries to establish whether there are syntax errors. It checks the existence of objects utilized in SQL. It formulates the execution plans for these queries.
An AMP performs the following tasks: It works on a section of a table. It checks records made on disks. It performs functions relating to the generation of the final result. These include aggregation, joining, and sorting. It conducts space and lock management.
Retrieval architecture This architecture is used when a client makes a retrieval query. Disk This is a storage area for AMPs. They are termed as Vdisks or Virtual disks. How Teradata works Teradata works through the four components mentioned above. The systematic process in the parsing engine can be described as follows: Parser: This evaluates the syntax and passes the query to the next element system handler.
System handler: This evaluates whether the user has the right logging credentials to execute the query. Optimizer: This establishes the optimum plan for executing the SQL query. Dispatcher: This passes the query to the Access Module Processor. Applications of Teradata The following are some of the industries in which Teradata is used.
