Scala and Apache Spark in Tandem as a Next-Generation ETL Framework

Krzysztof Stanaszek describes some of the advantages and disadvantages of a scala-based approach to implementing and testing an ETL solution.

How to partition data in Tabular SSAS

Partitioning data is a standard SQL Server administration practice. Partitions enable independent administration of different slices of data. When a SQL Server Analysis Services (SSAS) tabular data model is developed and processed, data is read from the source system and loaded into the tabular data model configured in In-Memory processing mode. Every time the model is processed, the entire data set may not require re-processing. Only certain slices of data containing changes may require re-processing which can be achieved by partitioning data into logical slices. In this post, Siddharth Mehta looks at how to partition tables in Tabular SSAS.

Introducing DLM Techniques for a Multi-Database Multi-Server System

Although the techniques of Database Lifecycle Management can reduce the timescales for the delivery of new functionality to business systems, what if the database 'layer' consists of several large interdependent databases and data flows with replication and audit? Does DLM scale to this level of complexity? Margaret Cruise O'Brien starts a series of articles that describes the practicalities of improving DLM within an existing framework and team supporting a multi-database multi-server system, by describing some of the database management problems and solutions in an enterprise-scale database.

Question of the Day

A Quick Restore

While doing some testing of an application, I wanted to reset my environment after doing some testing with this code:

USE DNRTest

BACKUP DATABASE DNRTest TO DISK = 'dnrtest.bak'
GO
/*
Bunch of stuff tested here
*/RESTORE DATABASE DNRTest FROM DISK = 'dnrtest.bak' WITH REPLACE
What happens if this runs, assuming the "bunch of stuff" isn't anything affecting the instance.
