Teradata Career Architecture and Components

The architecture of Teradata RDBMS is designed using shared-nothing architecture.

Teradata Career database systems are of two types:

SMP (Symmetric Multi-Processing)
MPP (Massively Parallel Processing)

SMP system is a single NODE system with multiple CPU-sharing memory pools. MPP system has two or more NODES connected by a component called BYNET.

Teradata architecture contains the following components:

1. NODE

This is the collection of hardware and software components and the building block of its database system where the processing occurs. Channel system and network system can be integrated with NODE.

2. PE

Parsing Engine (PE) is a component that interprets SQL requests receives input and transforms the data. The data is transferred through the BYNET to the AMP.

3. PDE

Parallel Database Extension (PDE) runs the operating system on each NODE. It runs Teradata Career Component in parallel.

4. AMP

Access Module Processor (AMP) is a virtual processor designed to manage the database. It sorts, aggregates, and formats data. Each AMP is associated with one virtual disk where there is data stored. It helps to retrieve or update data.

5. System disks

System disks are a part of the NODE that stores data rows. It includes:

The activities of the database are stored on disk arrays.

6. VPROC (Virtual Processor)

VPROC combines one or more software processes in the OS multi-tasking environment. In Windows OS, VPROC is a single software process. The two types of VPROC are AMP and PE.

7. BYNET (Banyan Network)

BYNET combines hardware and software that provides high-performance networking between the NODES. BYNET is a message-passing layer. It helps the NODES to communicate in a faster way. BYNET hardware and software components handle the communication between the VPROCs. The hardware of BYNET includes boards and cables. The software of BYNET consists of an interface between PDE and BYNET hardware.

The essential features of BYNET include the following:

Fault Tolerance
Load Balances
High Scalability

Teradata Career Data Warehouse System Components

The following are the components:

1. Teradata Database Server

Its Database Server manages a large number of data. It helps in scalability and ensures the integrity of the data.

The database has several modules, which are mentioned below:

Teradata Database Window – Has control over the operation of the Teradata Career Database
Teradata Gateway – Controls communications, client messages, and encryption
Parallel Data Extensions – Enables parallel processing in the Database
Teradata Database Management Software – This includes Parsing Engine, Access Module Processor, and the File System

2. Teradata Tools and Utilities (TTU)

The important Teradata Career client tools are listed below:

Teradata SQL Assistant – This is a graphical tool that helps the database development and administration process easy
Basic Teradata Query (BTEQ) – This is a batch query processing facility
Loading tools – Helps in loading and unloading applications like TPump, FastExport, Parallel Transporter, and others
