Analytical Functions in oracle explained with real examples
 
25:24
This video explains analytical functions and how they are implemented in real projects. Analytical functions are somewhat similar to aggregate functions,but they offer much more. Why use analytical function ? They allow you to write fast and concise queries which otherwise will involve self join and long processing times They allow you to perform aggregate functions independently on sets of partitions. You can access values from previous rows in current row and you can restrict the window on which you want to apply this analytical function. I have given additional practice exercises along with the dataset so that you can comfortably work with analytical functions. You can find the sample problems along with dataset in the below link. http://www.internshipsfromhome.com/oracle-analytical-functions-ddl-and-dml/

How Does the Phyiscal Location of Rows Affect Indexes?: Finding All the Red Sweets Part 2
 
09:25
In part one of the red candy series, Chris compared the efficiency of using a index range scan and full table scan to access data. He found that a full table scan was more efficient when fetching more rows than there are table blocks. This analysis made a big assumption however. It worked on the presumption that there was no correlation between the order of candies in the document and which the bags they were in. In this episode tests this assumption. Chris looks at how the physical order of rows in a table can affect the efficiency of indexes on it. He discusses how Oracle tracks this via the clustering factor. ============================ The Magic of SQL with Chris Saxon Copyright © 2015 Oracle and/or its affiliates.

Does SQL table join order matter?
 
14:10
Have you ever wondered if the order of the tables in your FROM clause matter?

Composite Range-Hash Partitioning Composite range-hash partitioning partitions data using the range method, and within each partition, subpartitions it using the hash method. Composite range-hash partitioning provides the improved manageability of range partitioning and the data placement, striping, and parallelism advantages of hash partitioning. Composite Range-List Partitioning Composite range-list partitioning partitions data using the range method, and within each partition, subpartitions it using the list method. Composite range-list partitioning provides the manageability of range partitioning and the explicit control of list partitioning for the subpartitions. Composite List-Range Partitioning Composite list-range partitioning enables logical range subpartitioning within a given list partitioning strategy; for example, list partition by country_id and range subpartition by order_date. Composite List-Hash Partitioning Composite list-hash partitioning enables hash subpartitioning of a list-partitioned object; for example, to enable partition-wise joins. Composite List-List Partitioning Composite list-list partitioning enables logical list partitioning along two dimensions; for example, list partition by country_id and list subpartition by sales_channel. Composite Hash-Hash Partitioning Composite hash-hash partitioning enables hash partitioning along two dimensions. This technique is beneficial to enable partition-wise joins along two dimensions.

Chapter 6 Relational Databases
 
01:27:25
Relational databases implement the relational model which is one of the most popular logical and internal data models in use nowadays. It was first formalized by Edgar F. Codd in his seminal paper “A relational model of data for large shared data banks” which appeared in the well-respected journal Communications of the ACM already in 1970. In this chapter, we first introduce the basic concepts of the relational model and then formally define them in a next section. This is followed by an overview of the different types of keys, which are an essential building block of the relational model. The relational constraints are summarized next followed by an example of a relational data model. Normalization will also be reviewed, as a procedure to remove redundancies and anomalies from a relational data model. After having introduced the need for normalization and some informal guidelines, we zoom into functional dependencies and prime attribute types and discuss how both can be used during a multi-step normalization procedure. To conclude, we discuss how to map both ER and EER conceptual data models to a logical relational data model. The next chapter then zooms into SQL, which is the DDL and DML used by relational databases.

Microservices: Get Rid of Your DBA and Send the DB into Burnout
 
39:03
Franck Pachot, Database Engineer, CERN The database is always a problem: it is a single point of failure for applications; it makes any continuous integration/delivery impossible; the DBA is a drag on your agile developments; and any interaction with the database is done with unmaintainable, complex, old-style SQL queries. Those are the reasons why modern architects want to get all code out of the database and even the data moved out to caches, local to CQRS microservices. But there are drawbacks with this approach, and doing it incorrectly may show the worst once implemented. This session focuses on the antipatterns and shows, with facts and measurements, what can be wrong in the implementation. This knowlege may help you design your applications with scalability in mind.

Oracle Data Guard Tutorial - Open the Standby Read Only (Part 2 of 4)
 
16:49
This tutorial provides a quick review of what Data Guard is, and then goes on to show how you can extract value from Data Guard in every-day usage: how you can use it to enhance performance, and to reduce (yes, reduce!) your need for Oracle licences. Opening the standby database read-only. This has in fact been possible since the automation of redo transport and redo apply when it was first introduced in release 8i. Redo is received on the standby database but is not applied. So the redo is written to the RFS, slave to standby logs, archive to standby logs into archive logs but there's no apply done. So recoverability is not compromised. There's still no danger being lots of data. You're still receiving. The thing is open read-only. What does that mean? It means you can run queries against it. You can offload all your heavyweight queries from the primary to the standby. When I say all of them, even queries that require vast massive temporary space, those horrendous queries, those doing hash joins between multi gigabyte tables, they'll be generating many gigabytes of temporary data. You can write temporary data. Provided that you're using proper temporary tablespaces which you're certain you should be, you can run any query no matter how big, no matter how much temporary data it needs. You can also write audit data and this is important because with version 11, there's quite a lot of auditing enabled by default. By default, that auditing goes to the database, writing database tables. And you can't write to a database table in a read-only database. That we can configure for automatic switching and direct the audit records to the operating system or the trail instead. The queries you run, why is this such a good facility? First, you're taking stress off the primary. I'm sure that we're all DBAs here and we all know how difficult it is to tune your database or a concurrent workload that includes both high volume DML and includes heavyweight queries. Basically, you can't tune that way at all. Offloading the queries to the physical standby will reduce a lot of stress from the primary. So your DML should run significantly better and you can even do a certain amount of tuning on the standby to tune for optimal query performance. The most obvious tuning one would do, would be the memory parameters. No one could for example give the primary a massive PGA aggregate target and the much smaller SGA target or use indeed automatic memory management, perhaps cell tuning. One can adjust many parameters to do with tuning the optimizer to drive the optimizer to a certain execution plan, to exploit the environments. All that can be done on an open read-only database. How does one do it? It really couldn't be simpler. If we look at my physical standby here, this thing database role, physical standby - and if we select the open mode from v$ database, we find this in mount mode. How do we actually open at read-only? First off, we have to stop the recovery process because remember redo is received but no applied. You have to cancel the recovery. So "alter database recover managed standby database cancel." That will give us a read consistent version of the database. The command is intelligent enough to know that there might be incomplete transactions. Long-run transactions could've been partially received. We will end up with a read consistent version. To cancel it, all we do is alter database open read-only. It is that simple.

How Does a Hint Affect an Adaptive Join?
 
08:52
Since adaptive joins can control their behavior, using either a hash or a nested loops, what happens when you start putting join hints into the mix. Let's explore that and see how the adaptive join, the execution plan, and the query performance is affected. -~-~~-~~~-~~-~- Please watch: "Extended Events Live Data Window " https://www.youtube.com/watch?v=UDtXjewvqmM -~-~~-~~~-~~-~- #sqlserver #performancetuning #adaptivejoin

How to Structure Data for Import into SPSS - Rectangular Data (Ep.4)
 
11:09
If you plan to analyze data in IBM® SPSS® Statistics, your data must be organized and structured in a specific way. This is incredibly important information, especially if you will be collecting data in Excel then later importing it into SPSS for analysis. Planning ahead can save you hours of time and effort because if your data are not rectangular, you cannot import them into SPSS. Learn this information before you begin data collection so that your project will go smoothly.
