So, what’s going on in your databases world this week, young man? I paused, as always, a little unsure of what I was getting myself into. I’d been having these little “technical chats” with Gran ever since her ‘computer incident’, when a blue screen informing her of a “Fatal error: catastrophic failure“, had thrown her … Read more

More SQL Server Features that Time Forgot

SQL Server produces some great features, but it would be impossible to get them spot-on target every time. We are now quietly advised to use caution about using some of them, such as AutoShrink or the Index Advisor. Others, like the database diagramming tool, almost seem to have been quietly abandoned.

Overcoming the Challenges of Microservices and Docker Containerisation

A microservice architecture can provide great benefits to certain types of applications that have pronounced troughs and peaks in demand, such as web-based shopping apps. With containerization, there is the promise of deploying containerized services in a matter of seconds to deal with demand.

Abstracting System Time in ASP.NET Applications

When designing web applications, it is a good idea to be cautious about the way you handle the time of day and calendar. It can get complicated when you have servers in different time zones and the user of the time-sensitive application may, or may not, want his local time, including daylight-saving adjustments, to be assumed. Problems pop up unexpectedly, so maybe it is better to tackle the issue up-front. Dino Esposito explains.… Read more

The Quick and the Dead Slow: Importing CSV Files into Azure Data Warehouse

Although Azure Data Warehouse is part of the bright new jewellery of the Microsoft Data Platform, the old Data Warehouse rules still apply where data imports are concerned. When it comes to data import, it pays to choose the fastest import method first and prepare your data first to ensure that it is compatible with your choice. The subtlety is in the details, as Feodor explains.… Read more

Questions About RDS SQL Server You Were Too Shy to Ask

There are a number of different ways that you can host SQL Server. RDS SQL Server, for example, uses SQL Server within AWS as a simple database service, much like a more versatile alternative to MySQL. Obviously, it is a compromise, in that you lose many of the extras beyond the database. Laerte Junior answers those questions about RDS that people seem to assume you know the answers to, but which you may be too shy to ask.… Read more

Consuming hierarchical JSON documents in SQL Server using OpenJSON

Over the years, Phil was struck by the problems of reading and writing JSON documents with SQL Server. Now that SQL Server 2016 onwards has good JSON support, he thought that the articles would be forgotten. Not so, they continue to be popular, so he felt obliged to write about how you can use SQL Server's JSON support to speed the process up.… Read more

The Wrong Way to Clean Up the Internet

Having successfully fought several privacy battles, granting people the right to have themselves taken off Google search, and to have their records deleted from databases, it looks as if the European Union may soon want to regulate and license what you can watch on YouTube or other video content sites, and the audio-visual content you … Read more

Six Scary SQL Surprises

The working life of the DBA can be punctuated by surprises, but they aren't generally nice surprises. This is especially true if the DBA is not checking and monitoring the databases for obvious things such as database corruption, and disk space. However, the really scary surprises are less obvious and provide fewer warning signs. Brent Ozar gives six scary surprises that can be avoided by the shrewd DBA.… Read more

Managing the Password of the Application’s User

How can you ensure that passwords conform to a policy, even if they are used for connecting applications to databases? Absolving them from the policy is a security risk and you don't want to trouble the users with password changes.

Providing the Necessary Tools and Reports for Very Large IT Projects

For the larger development project using Agile/DevOps, there will always be the problem of comprehensive tooling and reporting. An all-encompassing ALM Integrated Development Environment will have some of what you need but is unlikely to meet your special requirements; Neither will a DevOps toolchain. Where do you start?

Creating a C++/CLI Wrapper

The C++/CLI is a dialect of C++ that is designed to work with the Common Language Infrastructure (CLI). It is a replacement for 'Managed C++' and makes every feature of the CLI easily accessible from C++. Mircea demonstrates the architecture that is involved in a C++/CLI wrapper that allows you to use both managed and unmanaged code, and to provide the choice of controlling memory directly.… Read more

SQL Code Smells

Some time ago, Phil Factor wrote his booklet 'SQL Code Smells', collecting together a whole range of SQL Coding practices that could be considered to indicate the need for a review of the code. It was published as 119 code smells, even though there were 120 of them at the time. Phil Factor has continued to collect them and the current state of the art is reflected in this article. There are now around 150 of these smells and SQL Code Guard is committed to cover as many as possible of them. … Read more

Why is My Database Application so Slow?

When your application is running slowly, the reflex action is to blame the database queries. It is certainly true that some of the more extravagant delays can be fairly blamed on a missing index or unnecessary locking, but there are other potential villains in the drama, including the network and the application itself. Dan Turner points out that you could save a lot of time and money by working out for sure where the problems lie before diving into the detail.… Read more

Mixing MongoDB and Relational Databases in the Enterprise

Your Agile developers want MongoDB, or a similar document database: your Ops people are concerned about security and backup, and Governance are muttering about transactionality and data transfer between systems. Do you restrict your developers from rapidly-evolving the data design for their domain or do you embrace the joys of NoSQL unconditionally? If you accept a polyglot database environment, where the NoSQL lambs coexist with the relational lions, how do you provide tools and common database concepts that everyone can use and understand?… Read more
