    <p>Is it advisable to zero-in on design of a component or architecture of a software with performance in mind? What I mean is, how ready should the design/architecture be to used in a performance-intensive environment?</p> <p>While designing components, should we just follow good OO principles and just ensure that the component is 'extendable'. This way we tweak the design a bit here and a bit there as and when we run into performance issues. Although this way, we would often land up in performance issues where tweaking software a little bit might not help.</p> <p>Alternatively, should we come up with a design, although complex, makes performance issues a cakewalk. We would still need to tweak the software, but the tweaking is often very simple as the design is performance-oriented.</p> <p>Note: In neither of the cases listed above am I trying to tune the performance of the software before running into performance issues. To re-phrase the question, should the design of the software be performance-oriented?</p> <p>Please do not answer me saying that it all depends on the environment in which a software is expected to run. The reason being that clients of any industrial-grade software just seem to want more and more and more all the time. You may not <em>plan</em> your software to be constantly running in performance-intensive environments, but what if it has to? Should we then re-design the software when we sense that?</p> <p>This question has been troubling me from a week and I don't have an answer yet. What is your take on this?</p>

    1. COSorry, but "it depends" is the only true answer. Often you have to choose a balance between maintainability and performance.

    2. CORetagged - changed from "java" to "language-agnostic" and "oops" to "oop"; added "best-practices". Hopefully that will give a wider audience. I won't re-edit them if the OP chooses to change them back.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
