Regular Expressions: Say What?

It has been possible since Oracle database release 10, Regular Expression support with its own set of functions. But getting started with Regular Expressions is not easy. Most database developers would avoid them if at all possible.

With current release of the Oracle database, Regular Expression syntax becomes more important. You can use them to redact data with DBMS_REDACT and to search for patterns using the Match_Recognize clause.

This session covers the basic syntax and gives you an easy introduction with Regular Expressions with plenty of code samples.

How to Find Patterns in Your Data with SQL

SQL is a powerful language for accessing data. Using analytic functions, you can gain lots of insights from your data. But there are many problems which are hard or outright impossible to solve using these.

Introduced in 12c, the row pattern matching clause, match_recognize, fills this gap. With this it’s easy to write efficient SQL to answer many previously tricky questions.

This session introduces the match_recognize clause. It will use worked examples to show how it works and show how it’s easier to write and understand than traditional SQL solutions.

This talk is for developers and data analysts that need to do advanced data analysis.

Flashback – not JUST for DBAs

Most people think of the Flashback features in Oracle as the “In Case of Emergency” switch, to only be used when something catastrophic has occurred on your database. And yes, it is true that Flashback will definitely help you in those 3 seconds after you press the Commit button and you realise that you probably needed to have a WHERE clause on that “delete all rows from the SALES table” SQL statement. Or for when you run “drop table” on the Production database, when you were just so sure that you were logged onto the Test system. But Flashback is not only for those “Oh No!” moments. It offers much much more in modern application development. It enables benefits for developers ranging from data consistency to continuous integration and data auditing. Tucked away in Enterprise Edition are six independent and powerful technologies that might just save your career but they will also open up a myriad of other benefits of well.

Avoid “Horror Queries”: Keep Your SQL Simple and Fast

SQL is a powerful and efficient query language when used correctly. But inefficient and inappropriate SQL statements can cause massive performance problems. Instead of solving such issues with additional indexes, optimizer hints, SQL profiles or SQL plan baselines, a much better and more sustainable solution is often to rewrite the SQL statements and to reduce the complexity of the queries.

During performance tuning tasks for my customers, I’m often confronted with complex SQL statements. Many of these statements were developed years ago and changed several times by people that either had not enough SQL skills or had not the time to understand the original query in detail. This can lead to queries that are not only very slow, but also hard to understand – for the developers as well as for the query optimizer. By transforming these SQL statements into simpler queries, the optimizer can calculate better estimations and generate faster execution plans.

In this presentation, some real-life examples of terrible “horror queries” will be shown and rewritten into simpler, more elegant and faster SQL statements. The goal of the presentation is to show how to improve the performance of a query by factors with appropriate SQL statements and powerful Oracle SQL features.

Explain the Explain Plan – Interpreting Execution Plans for SQL Statements

The execution plan for a SQL statement can often seem complicated and hard to understand. Determining if the execution plan you are looking at is the best plan you could get or attempting to improve a poorly performing execution plan can be a daunting task even for the most experienced DBA or developer. This session examines the different aspects of an execution plan, from selectivity to parallel execution and explains what information you should be gleaming from the plan and how it affects the execution. It offers insight into what caused the Optimizer to make the decision it did as well as a set of corrective measures that can be used to improve each aspect of the plan.

Harnessing The Power Of Optimizer Hints

The goal of the Oracle Optimizer is to examine all possible execution plans for a SQL statement and to pick the one with the lowest cost, which should be the most efficient. From time to time, it may become necessary to influence the plan the Optimizer chooses. The most powerful way to alter the plan chosen is via Optimizer hints. But knowing when and how to use Optimizer hints correctly is somewhat of a dark art. This session explains in detail how Optimizer hints are interpreted, when they should be used, and why they sometimes appear to be ignored.

Database Stats. Doing It Right, The Easy Way

Oracle Statistics are critical to the optimizer and your system performance, whether on-premises, in the Cloud or Autonomous.
If your statistics do not reflect your data, the optimizer will be working with incorrect assumptions and you may get poor execution plans.
Your stats are always wrong. They contain estimates, guesses, assumptions and analysis of partial data samples.
This talk will show my preferred approach to gathering database stats, ensuring you have the best stats that you reasonably can for your data and keeping your execution plans stable and accurate.

I AM SPARTACUS – Making sense of IDCS

Oftentimes the journey to the cloud stems from a yearning for “Cloud removes all issues we used to have”. While cloud solutions do alleviate many tasks and eradicate many issues commonly found with on-premises products, it also adds new pieces to the puzzle which need to be understood in order to fully unlock their potentials and allow customers to realize all of the benefits.

Migrating on-premises OBIEE to Oracle Analytics Cloud is a straightforward enough task. The integration of a central cloud analytics platform with other clouds, on-premises data sources and security mechanisms at the same time, however, is a key factor that’s often neglected or misunderstood. In reality it is one of the most crucial success factors to any initiative.

Success is not about eye candy – it’s about what makes an initiative actually successful as in integral part of the enterprise.

The Oracle Identity Cloud Service IDCS is the unifying platform and methodology which allows you to integrate all the distinct security concepts and technologies playing a part in a modern, heterogeneous and hybrid infrastructure.

This presentation aims to walk through the technical steps needed to configure LDAP, IDCS and OAC.

Making Sense of Location: Tracking, Visualizing & Analyzing Objects in 2D, 3D & 4D

Location information is a common element in many Big Data scenarios, in Smart Cities or in the context of the Internet of Things. This kind of positional data can explicitly be expressed as coordinates if it comes from a GPS sensor or it can be implicitly included in a postal code, a city or a landmark name, occurring in two or three dimensions, potentially even using time as the 4th dimension. For many years, Oracle has been offering technologies to manage, to analyze and to visualize this kind of data. In this session, we will review the basics of database development for geospatial data, both on-premise as well as in the cloud. We will look at tracking and tracing of moving objects, spatial data visualization, as well as more advanced analytics based on road networks. Two customer projects in Germany and Belgium are included to round off the session.
