SQLAlchemy

SQLAlchemy is an open source python library which provides an abstraction over relational databases making them easier to work with. It provides a SQL expression language to generate SQL queries and has an object relational mapper that allows you to express database queries in terms of classes and relationships between them. Using SQLAlchemy has several advantages:

(1) Write generic python code to work across different database backends.
(2) Interact with the database through python objects instead of writing SQL.
(3) Expose data to powerful python libraries.
(4) It can support the features of the underlying database.
(5) It's free.
 

The Windows installation of Studio and Studio Express supports preconfigured preferences that can be provided during the installation process. The feature focuses on those preferences that pertain to database interactions.

This article will introduce you to the new user experience provided by Teradata Studio's Administration Perspective; an improved interface for creating and modifying database objects.

The Teradata Schema Workbench product provides a utility program that facilitates the proper definition and configuration of the metadata repository database (BIM_REPOSITORY) and associated tables required by the Schema Workbench, Teradata OLAP Connector and Teradata OLAP Server products. While it is possible to use tools such as Teradata Studio or Teradata SQL Assistant to manually define and configure the metadata repository, it is strongly advised that you utilize the Schema Workbench Toolbox.

Teradata Studio's Copy Object Wizard allows users to copy objects by simply dragging the object from the Data Source Explorer tree and dropping it into the destination node in the Transfer View tree. Often users have created objects in their test database and wish to copy it to production, or copy objects from production into their test data lab environment. Database objects can be copied within the same database server or to a different database server. You can copy more than one object at a time by selecting multiple objects from the Data Source Explorer and dragging them to the Transfer View tree. Due to the external code location, External Stored Procedures and User Defined Functions can not be copied.

The Copy Object Wizard also allows you to filter out columns or column data when copying tables. You can also copy table data to an existing table, providing a map of source columns to destination columns.

Unity Data Mover (DM) is built to handle multiple requests to move objects concurrently. Understanding how DM processes these requests is benefitial to those looking to get the most out of their DM installations.

The easiest way to explain how DM handles work is to take a user request to move data and follow it through its life cycle. Along the way, we'll see how various user controlled settings affect the request and provide suggestions for how one might improve work throughput.

The Teradata Named Pipe Access Module (NPAM) provides an inter-process communication link between a writer process (such as FastExport) and a reader process (such as FastLoad).  The NPAM can also be used by Teradata Parallel Transporter (TPT) for data transfer activity.

Teradata Studio is a client based graphical interface used to perform database administration tasks on Teradata and Aster Databases, as well as copying data between Aster, Teradata, and Hadoop Database Systems. Teradata Studio is built on the Eclipse® Rich Client Platform (RCP), taking advantage of the RCP framework for building and deploying native GUI applications. It extends the Eclipse Data Tools Platform (DTP) to enhance Teradata Database access. Teradata Studio can be run on Windows, Linux, and Mac OSX operating systems. The Eclipse platform is designed as an open tools platform but architected so that its components (or a subset of its components) can be used to build RCP applications. This allows Teradata Studio to benefit from the many high quality Eclipse features available while focusing on value-add for Teradata.

With the Studio 15.11 release, a new user interface was introduced in the Administration Perspective. Refer to the article, New Studio Administration User Experience for more information.

In addition to this article, there is a Teradata Studio User Guide document now available on the Teradata Studio Download page.
