MERGING: Comparing the DATA Step with SQL
نویسنده
چکیده
Which merges files better: the SAS DATA Step or SAS SQL? Traditionally, the only way to merge files in SAS was via the SAS DATA Step. Now SAS provides a Structured Query Language (SQL) facility which also merges files. This tutorial compares and contrasts these two merge facilities. It examines the pros and cons of each merge technique. It looks at DATA Step code to perform specific merges and then looks at the corresponding SQL code to perform the same merges.

Data Merging and Visualization to Identify Associations between Environmental Factors and Disease Outbreaks
This paper describes data merging and visualization techniques for epidemiological and environmental surveillance data. The ultimate goal is to learn about associations between specific environmental factors and disease outbreaks. In such studies, environmental and clinical surveys often occur on different timelines. As such, data merging for the purpose of correlating the two data series can b...
متن کاملAutomatic Generation of Data Merging Program Codes
Data merging is an essential part of ETL (Extract-Transform-Load) processes to build a data warehouse system. To avoid rewheeling merging techniques, we propose a Data Merging Meta-model (DMM) and its transformation into executable program codes in the manner of model driven engineering. DMM allows defining relationships of different model entities and their merging types in conceptual level. O...
متن کاملDeclarative Data Fusion - Syntax, Semantics, and Implementation
In today’s integrating information systems data fusion, i.e., the merging of multiple tuples about the same real-world object into a single tuple, is left to ETL tools and other specialized software. While much attention has been paid to architecture, query languages, and query execution, the final step of actually fusing data from multiple sources into a consistent and homogeneous set is often...
متن کاملREGION MERGING STRATEGY FOR BRAIN MRI SEGMENTATION USING DEMPSTER-SHAFER THEORY
Detection of brain tissues using magnetic resonance imaging (MRI) is an active and challenging research area in computational neuroscience. Brain MRI artifacts lead to an uncertainty in pixel values. Therefore, brain MRI segmentation is a complicated concern which is tackled by a novel data fusion approach. The proposed algorithm has two main steps. In the first step the brain MRI is divided to...
متن کاملA Clustering Algorithm Merging MCMC and EM Methods Using SQL Queries
Clustering is an important problem in Statistics and Machine Learning that is usually solved using Likelihood Maximization Methods, of which the Expectation-Maximization Algorithm (EM) is the most common. In this work we present an SQL implementation of an algorithm merging Markov Chain Monte Carlo methods with the EM algorithm to find qualitatively better solutions for the clustering problem. ...
