I am working on a school management system
I want to store time table based on day, class, section, subjects, teacher and time.
I am confused about how to design table and how to store data.

It seems you are new in this community. Your question does not provide proper information. Guessing you are trying to create a table named 'time' with attributes day, class, section, subjects, teacher and time.
In phpmyadmin you can do this easily by create table option. In case of laravel you need to create migrations and use 'php artisan migrate' command. you can follow below link for further clarification- https://laravel.com/docs/7.x/migrations

I haven't found in documentation anything except "syncdb" command which create database tables from scratch. Is there any command to create and run migrations based on ORM model? Like in django? Add field, change type, etc.
No, orm.RunSyncdb(name, force, verbose) and it's command line equivalent only do a small subset of what tools like django's south can do.
Beego's orm can:
Create new tables from scratch
Drop all tables (force = true)
Add new columns as you extend your model
You need to handle dropping columns and any changes to the column parameters used to initially create the table.
Sadly beego doesn't include this feature, but no framework in go (as of today) does.
Instead they all relay that to other libraries to handle.
What you can do however is use goose for migrations:
https://bitbucket.org/liamstask/goose
or any other migration library as discussed in the following thread:
http://www.reddit.com/r/golang/comments/2dlbz5/database_migration_handling_in_go/
Remember that due to the modularity of beego you can also use any another orm (like gorm).
Feel free to look for : avelino/awesome-go in google if you want a list of tools/libs around the go ecosystem.
Yes, you can create migrations in beego now. Example, If you need to create a new table, you can start by creating a new migration file using the bee tool:
bee generate migration create_user_table
This command will create a file inside database/migrations folder. The file name contains the date, time and name of the migration.
For further details you can check this article https://ncona.com/2017/10/database-migrations-in-beego
I need to create an entity with the EXACT same columns and metadata as one I already have. I just need to give the new identity a different name as the data comes from a different customer and wanted to keep the entities separate; trying to be efficient in case I have to do this again.
Is this something I can do in MS Dynamics CRM 2011?
Also, will the ExtensionBase in Sql-Server be renamed to the new name if able to copy the entity is possible?
You can create and export an unmanaged solution containing only the entity you want to duplicate. After you need to manually edit the solution xml and change the relevant entries (now I don't know exactly which one, but I think only the entity name plus something else).
After you import back this unmanaged solution and you will get the new entity.
Hi i am a newbie to programming. I have 100 or so CT scans stored on a PACS (dcm4che). I am trying to link all patients to a teaching file database (simple django application) which will have teaching points on each case. Can someone direct me to a tutorial or a brief direction to what sort of programming will integrate the two? i do realise the generic nature of the question. I have 20 days to work on this so am willing to start from scratch
Thanks
I would recommend against anything specific as diving into dcm4che. Instead if you would like to use standard API, you should use the QIDO-RS/WADO API provided by dcm4chee.
One of the main author did also document how to install such instance here
I would suggest to bind yiur django app or project to the appropriate dcm4chee databese. Since you have all priviliges just create a new table within dcm4chee database which has a simple foreign key column named SOPinstanceUid. In this column you just store the SOPinstanceUId of your preferred images. Then of course you can additionally provide all columns you need for your teaching problem.
You can of course also create a seperate database and bind your django app to both databases and use the SOPInstance uid also as main key to establish the relationship between dcm4chee db and teaching db.
Within your django app you can then of course manage your teaching table or db and query the filenames of the images which you have selected for teaching.The key of this relationship is the SOPInstanceUID of the dicom image.
This approach just needs some expertise in SQL, some knowledge of the preconfigured database and of course django and DICOM.
I'm working with Django and I added a new model variable meaning that I need another column in my sqlite3 data base.
I have heard that I'm supposed to use sqlite> , but I am really confused when I start to use it. So, if that is part of the solution, can you be very specific on what to do?
thanks
MORE INFO:
my app is called "livestream" & and my class is "Stream"
I added the model "channel"
returns ---->
DatabaseError: table livestream_stream has no column named channel
You can ALTER TABLE to add a new column in Sqlite3 but not rename it nor drop it. Sqlite3 is a very useful database for bootstrapping your app. But sooner or later, you will need to change to a more robust/flexible database engine, say MySql or Postgresql.
Every time you add a new column to your models using Sqlite, you will need to recreate the schema (as far as I know, when you do migrations with Sqlite to add new columns, south complaints. see below). An approach I like more is use MySql with Django-South from the beginning, where I'm not sure about every aspect of my database.
Django South is an app for doing database migrations. It's very useful and the docs are a good starting point for beginners.
Every time you should make modifications to your database, you should consider them as migrations and use South.
Hope this helps!
I'm new to Drupal 7. Right now I'm trying to use D7 to build an interface that allows me to directly manipulate the tables in the database.
I have installed a couple modules such as Data, Migrate, Feeds, and etc. I managed to create a view to display the table that I created using Data Module, but I need to add and update the rows from the interface.
Furthermore, is it possible to set up relational tables so that I can update or delete related rows at the same time using Drupal?
Thanks in advance
Using the data module that is quite easy because it comes with the "Data Entity" submodule that creates an entity form for you. This allows you to update data table rows. It should add an edit button at the end of your data view for the table.
Using some basic custom code you can always create a form to add/update data to the table as well. For form creation please have a look at:
