TAILIEUCHUNG - Using the Python Database API with Red Hat Database

Data preparation includes the processes of cleansing, summarizing, and transforming detail and operational data into structures such as data warehouses and data marts that are suitable for BI reporting, data mining, scoring, and statistical processing. Many DBMSs provide some support for data preparation, such as filtering, aggregation, denormalization, and so on. However, SAS uniquely supports operations such as sampling, variable binning, imputation, and variable selection, which are typically not as robust in the DBMS functionality. Because the SAS language offers syntactic and semantic expressions that are not found in SQL, application programmers can implement more succinct, powerful data. | Using the Python Database API with Red Hat Database by Patrick Macdonald patrickm@ of Red Hat Inc. The Python Database API DB-API is a product-neutral interface to access and manipulate data stored in database management systems that allows developers to write database-independent Python applications. This document provides an overview of how to use the Python Database API with Red Hat Database RHDB a powerful and robust open-source database solution. Introduction Python is a portable platform-independent open-source programming language that has gained favor with developers for its versatility and ease of use. Python is an interpreted scripting language that allows developers to do everything from creating web sites to developing applications and scripts to accessing data in databases. The Python Database API DB-API Specification was produced by the Python Database Special Interest Group SIG to provide a product-neutral interface for accessing and manipulating data stored in database management systems. The DB-API allows developers to write applications that are transportable between database products. Red Hat Database RHDB ships with a Python Database API module which implements the Python Database API Specification Version . This document provides an overview of how to use the Python Database API with Red Hat Database a powerful and robust open-source database solution. We first present how to obtain and install the appropriate Python and database environment then we use a simple example application to illustrate some basic aspects of the Python Database API. Red Hat Using the Python Database API with Red Hat Database 1 Using the Python Database API with Red Hat Database Getting Ready to Use the Python Database API with Red Hat Database To use the Python Database API you need the Python interpreter as well as the Red Hat Database implementation of the Python DB-API . Getting and Installing Python and the Database API Code Python is .
