I want to know best practices for creation of features.
Normally Visual studio extension creates feature for each web part.
Or it good practice or we should create 1 feature for multiple web parts in one WSP?
I don't know of any best-practice, but I can see two ways (I can think of) of looking at it:
When you separate your webparts into several features, you have the possibility to activate/deactivate the different webparts at will. If one webpart has an error you can just deactivate it. When one webpart fails compiling, you still have the others running smoothly.
The downside is that you "clutter" the Sharepoint Interface, because you have to manage several Features instead of one. That goes for activating/deactivating as well as deploying/retracting.
If you have one feature it is all of the above, just in reverse. You only have one feature to activate/deactivate, which makes it faster to manager. But if that one feature fails in some way (or any of the webparts within) you can only deactivate the whole thing. The same goes for deployment/retracting. When one webpart within your feature fails you have to retract the whole thing.
Whether development is easier or harder depends on your preference. One might say that it is harder to keep a consistent configuration in one huge feature deploying a multitude of webparts, workflows and master pages (where was the entry for that workflow again? ah yes, in line 1112) - on the other hand you have everything in one place and don't have to search in several features.
I would really make it up to your personal preference. When you are deploying a Solution to a customer, the customer is certainly more happy to click/install/deploy the "MyCompany Super Solution Feature" instead of several smaller ones, in the end you don't install MS Word with several setup.exe's (and then again, you can choose what features of Word to install...)
It basically depends upon your requirements.
By the way, this problem is resolved in VS 2010 extension

Trying to figure out best way to setup Jira for cross-organizational project. We have a Continuous Delivery Program that will split off into separate backlogs to be worked by different teams based on Themes.
Wondering if we should setup one project to manage the overall high level project, and then different projects per theme of work that will be managed by the individual teams.
Are there ways multiple teams can work out of the same project but track their work separately (including if their work is Kan-Ban, Scrum-Ban or Sprint based?)
Regarding the question in the title. It's possible to move issues in JIRA from project to project. This feature is quite handy and you even can do bulk operations. See Moving an issue for more details.
Regarding structuring your projects. Out of the box there is no feature in JIRA to create such a workflow with projects and sub projects you have described.
A possible workaround could be using components as sub projects.
In this case you would create a project which act as your high level project and divide this project into several components. For components you can add a lead, do versioning but you can not set security permissions based on components for example. So this is not a perfect solution and have indeed some limitations since components are not projects. But you have to evaluate this approach by yourself if it is sufficient for you.
Another option would be to use a plugin e.g. Structure. I am pretty sure there are even more out there which promising to solve your problem. From my experience also using a plugin may be not the silver bullet you are expect. You have to evaluate it first if it really suits your workflow.
For the scenario you describe, the issues that you start from are probably more high-level than the actual work that has to picked up in the separate teams.
What I find to work well, is to keep 1 project (ie. Opportunity Backlog) for the high level issue (ie. an Opportunity) and when an opportunity gets detailed out, just create issues in the projects of the teams that will work on them. You can still link those issues to the opportunity so people who look at it can see what is happening in each team.
Another option is to keep everything in 1 project, but to make the relevant issues show up on the board for the team that has to work on them. A board can list issues of multiple projects. You just need to update the JQL query for the board accordingly. For more details, check the documentation. Note that working with sprints can get cumbersome if the same issues are listed on boards of multiple teams though. Best to configure things such that an issue is only displayed on the board of 1 team.
I wouldn't bother with moving issues too much. It's not a very user friendly action.
I watched some videos, read some blogs about it. SO has many questions and answers on that subject but I can not find anywhere exact answer for my question.
Almost every question and answer has a lack of usage context.
I have one middle sized, asp.net-mvc, monolith application which is running in one process on IIS. I want to (refactor and) go all the way with DDD (and CQRS without separated storage for reads and writes for now) but for me it looks like impossible mission without breaking some rules/guides/etc.
Bounded Context
For example I have more than one BCs. Each should not cross their boundaries which means should not share their storage. Right?
It is not possible if you use the whole known (everywhere scattered over the web) solution to work with NHibernate session and UoW.
Aggregate Root
Only one AR should be modified in one transaction. When others ARs are involved should introduce eventual consistency (if I remember those are Eric Evans words).
I try to do it but it is not easy in app like that. Pub/Sub not working as desired because if event is published then all subscribers are take their action within one transaction (NSB/MT does that way).
If event handlers wants to modify others ARs they should be executed in separated transactions, right?
Is it possible to deal with it in monolith application (application where whole code works in one process)?

I think you're setting yourself useless and harmful constraints by trying to stick to some "state of the art".
Migrating an entire application to DDD + CQRS is a massive undertaking. Some areas of it don't have well-documented beaten paths yet and you'll probably have a fair bit of exploration to do. My best advice would be to stay at a reasonable distance from "the way people do things". Both in traditional ASP.Net web apps because mainstream practices often don't match the way DDD+CQRS works, and in CQRS itself because the case studies out there are few and far between and most probably very domain specific, with a tendency to advocate the use of heavy tools which may not make sense in your context.
You may need to think out of the box, adopt things incrementally and refrain from goldplating everything. You'll be better off starting with very simple implementations that suit your needs exactly than throwing a ton of tools and frameworks at your codebase.
For instance, do you really need a service bus or could a simple Observer pattern suffice ?
Regarding NHibernate, most implementations out there use a (single) Session Per Request approach, but just because it's the most popular doesn't mean it's the only one. Have you tried using multiple ISessions (one for each BC) available at a more programmable level, such as per-action, or managed entirely manually ? Conversely, have you considered sharing a database between Bounded Contexts at first and see for yourself if that's bad or not ?
I’m writing an application with Ruby on Rails. This application will be delivered to a minimum of two different customer types. The base is always the same but some of the views differ. That’s mostly it. For now.
Is there any way, for example using branches, to use the same code base and separate only the views, for example? I read the Git manual for branching but am still not sure if this is the best way to achieve what I need.
Another idea would be forking. But, is that clever? If I change something in the code of fork A, is it easy to merge these changes into fork B?
Branching and forking in git is not bad at all, as the merge support is great (possible the best of al VCMs).
Personally, I don't like the idea of branching or forking a project to provide different customization as it can very quickly become really difficult, e.g. what are you going to do if you have 15 different deployments?
I think a better approach is to build the application so it behaves differently depending on some parameters. I'm well aware that sometimes the implementations are very different, so this might not be useful anymore.
Another approach is to build the core of your app in a GEM which acts as a service to the application, and the only thing you customize per client are the views. Of course, the GEM should be generic enough to provide all the services you need.
Please share with us what you decided, as there's no best answer for your question.
It would probably be better to make you product select between the types at either build or runtime, that way you can use a single set of source.
Otherwise it is possible with branches, and merging, but you'll have more difficulty managing things. Forking is basically branching at this level.
I agree with #Augusto. You could run your app in 2 different environments, ie production_A and production_B. From there, you could use SettingsLogic to define configurations based on Rails.env, then reference those settings in your app when selecting which view to use for example.
I am working on one big project. Now we need to add new functionality: scheduler managment.
It's not a main task of application, but it is quite complicated part of it.
Is it good idea to extract it as a separate application?
It will share some data (users and some other personalities) and it will use the same database.
The main reason I want to do it is to simplify main application.
I understand, that it is mayby too wide question. But maybe you can share your expirience of developing this kind of applications and maybe there are any articles I can read and world-wide best practices.
While others have mentioned some of the benefits of separating the applications, I'll touch on a couple of reasons why you might NOT want to separate the code.
You're going to need to maintain a single set of tests, especially if both applications are sharing the same database. If you don't do this, it's hard to predict when changing one application would break the other, especially if the applications start to need different things out of the database.
The two applications are obviously going to have a lot of overlap (users, for example). Separating into two applications could potentially force you to duplicate code, since rails by default has some pretty specific ideas about how a rails application should be structured. If your applications are sharing certain views, for example, what will you do to coordinate change in both applications when one application wants to modify the view?
Neither of these is insurmountable, but rails is easiest to develop when you follow rails conventions. As you begin to deviate, you end up having to do more work. Also, don't take either of these points as invalidating the other answers here, but merely counterpoints that you need to think about.
When you can use the functionality in other projects too, then I would separate it.
Maybe you can create a rails engine to share it easily between projects.
Consider asking yourself "What about re-usability?" Is the new scheduling functionality likely to be re-usable in another context with another application? If the answer is "yes," then perhaps making the scheduling management more modular in design will save you time in the future. If the answer is "no," then I would think you have more leeway in how tightly you integrate scheduling management with your existing app.
The practical difference here would be writing generalized scheduling management functionality that has assignable tables and methods upon which to act versus more 'hard coding' it with the data/code scheme of your 'onebig project.'

Adding management-tools into a web-app often complicate deployment, is my experience. Especially when the use of your application grows, and you need to performance-tune it, dragging along a huge "backend" may be problematic.
For sake of deploy-, scale- and test-ability, I prefer my applications to be small and focused. Sometimes it even pays off to have the entire admin-enviroment over REST-XML-services.
But as other answers point out: this is more a "it depends" solution. These are my €0.02.
I know there is a lot of talk about BPM these days and I am conscious that some may see it to be a craze rather than a fundamentally important piece of software.
As someone from what most would call 'The Business', I have been doing my best to learn about BPM to ensure we continue to make decisions that not only make sense to the business, but IT as well.
I have noticed while reading that mention is made to application workflow when sometimes discussing BPM. I hadn't given this much thought until recently.
Therefore, what is the difference? When would you use one and not the other?
BPM is about the process and improving it, which takes into account users and potentially more than one application,e.g. an ERP system may have more than one application to it, though there may be other uses of the term. Note that the process could be viewed without what applications or technologies are used.
Application workflow is how an application is used to go from a to b. Here it is a specific set of code that is used and what happens over the course of an application getting from a to b. In this case, the application is front and center rather than the process.
Does that provide an answer? Another way to think of it is that multiple application workflows can make up a system which is used in a process that can have BPM applied to it.
Late to the game, but workflow is to database as BPMS is to DBMS. (Convenient how the letters line up, huh?)
IOW, BPM(S) is traditionally meant to refer to a particular framework/application that allows you to manage business processes: defining them, storing them, versioning them, measuring them, etc. This is similar to how a DBMS manages databases.
Now, a workflow is a definition, much like a database is a definition. In the former case, it is a definition of operations/work (Fufill Order), steps thereof (Send Invoice) and rules/constraints on the work (If no stock, send notice). In the latter, similar case, it is a definition of data structure (CREATE TABLE) and constraints (InvoiceTotal must be > $0.00).
I think this is a potentially confusing subject, particular as some development environments use a type of process flow model to generate user facing applications (I'm thinking about Outsystems here, for example).
But, for me, the distinction is crystal clear. Application workflow, as people talk about it, refers to a user's path through an application, i.e. the pages they complete/visit, the data they enter, etc. on their way to completing a transaction of some sort. Application orkflow is a poor term for this though, I think application flow would be more meaningful.
BPM on other hand, is about modelling and executing a workflow process. By workflow, in this context, I mean a series of discrete steps (or tasks) that have to be completed (either programmatically or via human interaction) in a certain order to complete a process. These tasks can be implemented as individual application modules (each with their own "application workflow", see above). The job of the workflow engine is to make sure that these separate steps are assigned to the right people (of groups of people) in the right sequence, and that overall the process completes in an orderly way.
I don't think there's a clear answer to this at all. These are words, as opposed to theoretical concepts. If you add the word "checklist" into the mix - that just turns out to be a linear version of a process (but you can have conditionals in checklists - making them a workflow).
I am not sure how to help in reframing this question, but it's almost as if no answer can ever be possible. My own thoughts are at https://tallyfy.com/improving-efficiency-workflow-vs-business-process-management/
