 Is Perfect Software Attainable? I was in a social media discussion the other day where someone said âPerfection isnât real, but progress is.â This started me thinking, is there really no perfection? Can you not actually create a piece of software that is perfect? Of course you can. As long as your requirements are perfect, and the code does exactly what the requirements want, and you get everything exactly right, you can attain perfection. But letâs be realistic, perfection is rarely attained unless your requirements are akin to a school assignment that says: âPrint out âHello Worldââ Most requirements documents contain far more than you can realistically accomplish, and modern computing is a complicated menagerie of technologies all strung together to meet complicated requirements to not only accomplish a task, report on that task, but also predict how many users will come back and do that task again one day (among other things). The concept of the MVP has taken over in the past few years, and if you havenât heard the term, it is not as positive as the acronym sounds to any sports fan. It means Minimum Viable Product. It basically should mean to ship the minimum product that will do something positive for the customer and get them closer to that perfection they wanted. But how do you know what the customer wants? Will you ever give them what they want if you donât attempt to capture what their âperfectâ solution would look like? This is why perfect must be a real concept, even if it is rarely attainable (and I will freely admit, rarely understood even well enough). If you don't even try define what the perfect solution is, what are you targeting? Mediocre? Just OK? Good enough? Determining what perfect is, is a lot safer and easier than trying to nail down good enough. If you try to define your customerâs desires in the terms of âthis is good enoughâ without getting an idea of what their perfection is, as timelines slip and features fall off, you are negotiating against what they had already said was their bare minimum good enough, rather than their actual desire for a perfect solution. So, by definition, you end up with an MVP that isnât good enough and may not even be minimally viable. Part of defining perfection is to tag parts of the requirement as necessary versus the ideal that you are wanting from the perfect solution. Last thing⦠perfect changes over time. The reason for iterative development, defining mere slices of the overall perfection, MVPs, good enough solutions, and all that is simply the problem of time. Back in the dark ages of waterfall development, people spent lots of time defining perfect, but by the time the code was being written, and certainly near that glorious final release⦠perfection had often shifted for one reason or another and the customer wanted something else. Sometimes entire generations of hardware and software would occur, sometimes the process was so slow the problem you were trying to solve had already failed. Perfection is certainly achieved on rare occasions, but for the most part, it is only a hypothetical target that you know is somewhat unlikely and likely to change even if you did attempt to attain it. It is just that without that target, you are shooting for imperfection and that is a slippery slope.  Louis Davidson (@drsql) [Join the debate, and respond to the editorial on the forums]( Â

Maximizing its performance is crucial, especially in highly concurrent environments where multiple transactions compete for resources. InnoDB, the default storage engine for MySQL, employs a technique known as Multi-Version Concurrency Control (MVCC) to address concurrency needs and enhance performance. In this exploration, we delve into the intricacies of MVCC, especially how it is implemented, understanding its components, its role in transaction isolation, and how to optimize and manage it for peak efficiency.

T-SQL and Query Languages [Effective Strategies for Storing and Parsing XML in SQL Server]( XML is a common storage format for data, metadata, parameters, or other semi-structured data. Because of this, it often finds its way into SQL Server databases and needs to be managed alongside other data types. Even though a relational database is not the optimal place to store and manage XML data, it is often needed due to application requirements, convenience, or a need to maintain this information in close proximity to other app data. This article dives into a variety of common XML challenges and the functionality included in SQL Server to help make managing them as simple as possible. [Snake draft sorting in SQL Server, part 2]( In my previous post, I showed how to borrow a snake draft concept from fantasy football, or a packing technique from the shipping industry, to distribute different portions of a workload to run in parallel. In the previous example, we determined a distribution order for databases based on size â though you can rank by literally any attribute (or combination of attributes). Once weâve determined how to build out this order, we may want to store that data somewhere because, sometimes, the source of that data is not directly accessible.

Web [Sails.js for web development]( Sails.js is a robust web development framework that runs on top of Node.js and uses JavaScriptâs asynchronous features to speed up the production of applications. Its adherence to the Model-View-Controller (MVC) architecture, which simplifies feature separation and code organization, is a critical component of its attractiveness. Rapid application development is facilitated by Sails.jsâ pre-built components and user-friendly APIs for developers. The framework is robust in scenarios involving real-time communication, which makes it perfect for interactive applications. Its Object-Relational Mapping (ORM) technology facilitates smooth integration with different databases by streamlining database interactions. Sails.js abstracts complexity and provides flexibility and scalability for projects of any size, from small-scale apps to large-scale business solutions, freeing developers to concentrate on application logic and user experience.  [RSS Feed]( This email has been sent to {EMAIL}.
