I know this is a duplicate question.
But even i couldn't find any tool to create JPA entity file from database source.
I used eclipse to do this. I only got DTO kind of classes with getters & setters.
Can anyone suggest some tools that create DAO files too.
TIA
You can use Telosys Tools,
an Eclipse plugin working from an existing database with customizable Velocity templates
See: https://sites.google.com/site/telosystools/
Eclipse Marketplace : http://marketplace.eclipse.org/content/telosys-tools
For JPA generation, use the JPA set of templates available on GitHub : https://github.com/telosys-tools
you can use netbeans instead of eclipse. After you create own project, you can select "JPA controller classes from entity classes" in netbeans menu. For example http://ensode.net/roller/dheffelfinger/entry/automated_dao_generation_from_jpa
Minuteproject is a generator tool and can generate JPA2 artifacts from Database.
You can instruct the generator to apply convention for your java code that do not follow your DB convention, but the mapping will be correct. (Example strip DB name prefix; table starting with ADMIN_ such as ADMIN_ENVIRONMENT are Environment (w/out Admin) as java class) For the moment there 20+ conventions that help you reshape your model to be less DB look-and-feel by more Java-OO-friendly.
If you want DAO minuteproject has a track BSLA that generate spring-integrated DAO

I'm working on a ASP.NET Core Razor pages project that includes IdentityServer and IdentityFramework with various customisations to the identity model -- all quite standard stuff.
What's not standard, though, is that someone has deicded to not use EntityFramework migrations but use DbUp instead.
I can see that changes to the C# model correspond to SQL files -- in the same way that they would correspond to EF migrations.
The mystery is how the DbUp SQL files were produced.
The filename are of the format M<timestamp>_<name>.sql -- where has the initial M come from?
None of the projects has the dbup-add-migration package installed (only dbup-core and dbup-sqlserver).
So: if, say, I edit a model class then what do I do to make the corresponding MyyyyMMdd_name.sql file?
At a conference yesterday, I learned about the importance of putting your database in source control. They showed us how to make a new Database project and import the database.
What I was wondering about is how I would change an existing project running on Entity Framework to utilize the database project's power?
Schema updates have always been done by using Entity Framework Migrations. I get that the Database project will be able to deploy database updates for me and save those update scripts to source control, but I would like to keep Entity Framework for querying my data (if that makes any sense at all).
Is it possible (or even: recommended) to use Entity Framework to access the database but manage the database using a Database project in Visual Studio ? How do you go about this?
I've tried searching for similar questions and using Google to find if anyone else is having the same problem, but no dice so far.
I should also state that I am considering using this in databases that also have stored procedures in them. These are not controlled through Entity Framework at all, and therefore are not in source control yet.
Thank you for your time.

Answer: I suggest you to see this course from Plural Sight : https://www.pluralsight.com/courses/code-first-entity-framework-legacy-databases
Is it possible (or even: recommended) to use Entity Framework to access the database but manage the database using a Database project
in Visual Studio ? How do you go about this?
Answer: Yes, it's possible and recommended. Your data project becomes the source of truth about the structure of your database. This is very powerful to keep control of all the changes and state of your database in one place (Visual Studio). The course from the first answer will teach you how.
I should also state that I am considering using this in databases that
also have stored procedures in them. These are not controlled through
Entity Framework at all, and therefore are not in source control yet.
Answer: I don't see any problem using stored procedures. The tool from the Plural Sight course will create the procedure in your source control and the reverse engineering will create a class/method for easy use of the proc.
I just came across the below alternative, which I didn't test though:
Generate Entity Framework Core classes from a SQL Server database project - .dacpac file
I believe this should be something to be considered
I developed an application like that, having 2 projects: application itself and the SSDT project for the database. The database changes were deployed via change scripts, and EF migrations were disabled in the application.
Everything worked fine, although it did bring a bit of an overhead. For example, it was a bit of a hassle to introduce major database updates / refactorings into the EF layer. For some reason, I was unable to reverse engineer database changes directly into the app, so I had to do it half-manually: creating new project, generate EF context for the entire database, and then copying new / changed files into the main application.
(Then again, it was almost 5 years ago. With luck, EF scaffolding has improved since then.)
Spring Boot is a good framework to develop quickly applications. However, when creating an application binded to database, it seems some of the work must be done twice (I'm using Flyway):
create table creation SQL queries scripts
create Spring entites containing corresponding annotations
run application : the flyway script generates the tables
Writing scripts AND entites can be time consuming, and without added value. Is it possible to do it only once?
Thanks
Just set theese properties on your configuration file:
spring.jpa.properties.javax.persistence.schema-generation.create-source=metadata
spring.jpa.properties.javax.persistence.schema-generation.scripts.action=create
spring.jpa.properties.javax.persistence.schema-generation.scripts.create-target=create.sql
The schema file will be generated automatically in the project root. Hope it helps.
You can also use JPA Buddy plugin. It has a "Show DDL" menu where you can visualize the sql script for a selected entity. Really useful when you want to avoid creating everything manually.
I have a large number of CakePHP 2 web applications, many of them use remote data over the custom DataSource. I'm reading the documentation of CakePHP 3, but I can not find instructions for creating custom datesource.
My next project also requires a custom DataSource (ArangoDB), so I planned to build it with the new version of CakePHP.
Please do specify where and how to build a DataSource in CakePHP 3.
Thank You.
Just look at the code of any existing database driver and see how it is built? There is nothing in the book yet about how to create your own datasource.
ArangoDB seems to be yet another NoSQL DB, so take a look at how this Elastic Search datasource is done. By a quick look I think you can use it as a base for your implemention, they seem to be similar.
I was facing the same problem so I decided to write my own models in CakePHP 3.x. If you want you can use it from here. hope you like it.
External database interface - Does Alfresco use point and click integration or is programming required to connect to the DB?
Can we use a 3rd party library like Google's zxing barcode reader to integrate with
Alfresco?

What do you mean by external database interface? If we're talking about using external databases, then it's just a matter of configuration.
It's generally not a problem to integrate 3rd party libraries. You just have to decide how to do that, e.g. using a custom Java backed web script or a custom action.
No point and click integration. It's build on Java, so you can write a custom Java class. The java class can be run scheduled, via a webscript, via workflow.
Of course, it's open source and fully build on Java, so integrate any 3d party solution into it. But you need to write everything yourself.
already exists a component for Alfresco Share which allow feature #1 with "zero code", in easy and flexible way.
Is available in Alfresco Addons http://addons.alfresco.com/addons/alfresco-metadbconnector-component.
Developed and maintained by VenziaIT (http://venzia.es).
We hope this help to the community.
