Part 4: DBAs guide to managing sandboxes

Image
This is the next part in my on-going series of posts on the topic of how to successfully manage sandboxes within an Oracle data warehouse environment. In Part 1 I provided an overview of sandboxing (key characteristics, deployment models) and introduced the concept of a lifecycle called BOX’D ( B uild, O bserver, X -Charge and D rop). In Part 2 I briefly explored the key differences between data marts and sandboxes. Part 3 explored the B uild-phase of our lifecycle. Now, in this post I am going to focus on the O bserve-phase. At this stage in the lifecycle we are concerned with managing our sandboxes. Most modern data warehouse environments will be running hundreds of data discovery projects so it is vital that the DBA can monitor and control the resources that each sandbox consumes by establishing rules to control the resources available to each project both in general terms and specifically for each project. In most cases, DBAs will setup a sandbox with dedicated resources. Howe...

Review of Data Warehousing and Big Data at #OOW14

Image
Data Warehousing and Big Data were at the heart of this year’s OpenWorld conference being across in a number of keynotes and a huge number of general sessions. Our hands-on labs were all completely full as people got valuable hands-on time with our most important new features. The key areas at this year’s conference were: Big Data SQL - One Fast SQL Query for All Your Data Database In-Memory - Powering the Real-Time Enterprise Mutitenant - Plug your data warehousing Into the Cloud All these topics appeared in the main keynote sessions including live on-stage demonstrations of how each feature can be used to increased the performance and analytical capability of your data warehouse. If you want to revisit the most important sessions, or if simply missed this year’s conference and want to catch up on all the most important topics, then I have put together a book of the highlights from this year’s conference. The booklet is divided into the following sectio...

Why SQL is becoming the goto language for Big Data analysis

Since the term big data first appeared in our lexicon of IT and business technology it has been intrinsically linked to the no-SQL, or anything-but-SQL, movement. However, we are now seeing that SQL is experiencing a renaissance. The term “noSQL” has softened to a much more realistic approach - a "not-only-SQL" approach. And now there is an explosion of SQL-based implementations designed to support big data. Leveraging the Hadoop ecosystem, there is: Hive, Stinger, Impala, Shark, Presto and many more. Other NoSQL vendors such as Cassandra are also adopting flavors of SQL. Why is there a growing level of interest in the reemergence of SQL? Probably, a more pertinent question is: did SQL ever really go away? Proponents of SQL often cite the following explanations for the re-emergence of SQL for analysis: There are legions of developers who know SQL. Leveraging the SQL language allows those developers to be immediately productive. There are legions of tools and applications u...

In one of my recent  blog post  I provided links to our OpenWorld data warehouse web app for smartphones and tablets. Now that the OOW team has released the hands-on lab schedule ( it is now live on the OpenWorld site) I have updated my smartphone and tablet apps to include the list of hands-on labs on a day-by-day basis (Monday Tuesday, Wednesday, Thursday). The list of hands-on labs can still be viewed in subject area order (data warehousing and big data) within the app via the “ Switch to subject view ” link in the top left part of the screen. I have also added a location map which can be viewed by clicking on the linked-text, “ View location map ", which is in the top right part of the screen on each application. The location map that is available within both the tablet and smartphone apps is shown below: If you want to run these updated web apps on your smartphone and/or tablet then you can reuse the existing links that I published on my  last blog...
