Recensioni su Visual LANSA
Noi usiamo dal 2004 Visual Lansa e IBMi (in passato) e vorremmo continuare ad usarlo in futuro
Commenti: Lansa in 16 anni di utilizzo è sempre cresciuto e si è adeguato al mercato anche se non in tempi brevissimi, speriamo che ora oltre a continuare a migliorare il prodotto e darci aggiornamenti in tempi brevi.
Aspetti positivi:
Visual Lansa si è sempre adeguato in autonomia alle nuove necessità del mercato e permettendoci di dedicarci solo alla parte di sviluppo applicativo e non all'adeguamento della tecnologia. Semplicità di apprendimento per ogni tipo di persona con poca o tanta cultura informatica, serve un ulteriore svecchiamento e uno sforzo maggiore verso le nuove tecnologia.
Aspetti negativi:
Manca l'integrazione con altri applicativi e dispositivi incluso IOT ed altro in modalità nativa e non come ora attraverso applicazioni .net sviluppate a questo scopo. Velocizzare la connessione hai dati anche senza server function la diversità di tempo di accesso è notevole. Continuare da parte Vostra a sviluppare il prodotto dal punto di vista tecnologico per sempificare a noi lo sviluppo sempre più veloce degli applicativi. Ritornare ad una gestione di licenze multiple su singola licenza come erano su IBMi fino all'avvento dell'RMLX questo ci permetterebbe di essere più competitivi e vicino ad altri prodotti sul mercato

Emiliano, Thank you for the review and providing your valuable feedback. In the past, we haven't done the best job at promoting new features available in our EPC releases. I think you will find our version 15, set to release soon, will provide you with greater integration and much faster app creation. We are working hard to improve communications with our customers so they know about new features as soon as they are available.
Lansa changed my whole development cycle
Commenti: We use Lansa for all new development ranging from iSeries green screens to Windows native to cross-browser web development to Mobile. It has turned staffs of mixed talent to single cohesive teams.
Aspetti positivi:
Time to deployment and reduced investment in having to always learn new skills to keep up. Historically, as interesting as it is for developers to learn new tech and find ways to engage the user and make things easier, this learning curve is time consuming and costly. It also does not insure consistency from developer to developer or adherence to standards. Lansa literally removes all of that. The developer is extracted from that layer and only has to focus on a single development environment that continues to improve and present simple ways to accomplish the latest technologies. It even insures adherence to standards through its common repository and wizards to create many of the most common processes. To take this whole picture to the next level, all of the code is portable, not only from system to system, but between OSs! If your company is using an iSeries and decides that it is time to move to another platform; you can move with it. No new learning curves. No re-development. Pick it up and move it over. I can't emphasize enough how valuable these traits are in environments that do not have the luxury of time and money to continually retrain.
Aspetti negativi:
Hang on tight with the training. Its important and well worth it in the end. But it is easy to get bored with. I find documentation to be sufficient if you have the basis of the training. Once you are through that and understand the concepts and the language, its gold.
Reduces technical baggage and allows you to focus on solving business problems
Commenti: By reducing the amount of technical baggage typically associated with web development, the time from conception to production is radically reduced. This also means that I can focus significantly more of my effort on solving business problems then solving technology problems.
Aspetti positivi:
I thing I like the most is being able to leave the technical baggage behind and really focus on solving problems for the company. For example, a full stack developer has a host of technologies they have to master to be effective and efficient at their job. If you are developing modern, responsive web applications chances are you are using something along the lines of Angular, React, Ember etc. Besides being yet another thing to know, it brings compilation, packing and deployment issues to the front-end development process. I don't worry about this any more. I develop a component and Visual LANSA handles the compilation, packing and deploying it to the browser for me. On the back-end side you have other frameworks to know. You've got to handle requests with WebAPI, MVC or Spring etc. You have to handle data access with Entity Framework, JPA, Hibernate etc. Then you may have an IoC container bringing everything together. With Visual LANSA Server Modules handle the request and you have just a handful of commands to interact with the database. All of the underlying plumbing that you normally have to deal with is removed as Visual LANSA takes care of it. One last thing that is really nice is the Visual LANSA Framework. If you are doing back office web development, i.e. not consumer facing, then the "Framework" becomes a huge time saver. Its essentially a "Shell" that you plug your components into and it handles all the complexities of the UI for you.
Aspetti negativi:
The thing I like the least is the debugger. The debuggers in Visual Studio, IntelliJ, Chrome's Dev Tools etc, set pretty high expectations and this where I think Visual LANSA could use the most help. Performance when debugging web components is pretty poor. Debugging non-JavaScript based objects like Server Modules, Functions, Windows Forms etc. is good. It's just JavaScript based components that seem to bog down and make stepping through code a very time consuming process. One example is not being able to inspect the contents of a list. You can see how many entries are in it, but you cannot see those entries without iterating the list. This typically leads to a lot of trace messages and essentially debugging through tracing.
Order Entry Platform for 18 Years
Commenti: Ultimately satisfied our business and user needs.
Aspetti positivi:
Satisfied our order entry GUI needs for our entire enterprise for over 18 years, and still going.
Aspetti negativi:
Ultimately we needed stronger integration and easier deployment options, and are slowly phasing out our LANSA GUI.

Robert, How great to hear Visual LANSA has been solid for you for 18 years! Are you on our latest version? 14 SP2 is geared toward easy integration and deployment. Even be on the lookout for some updated features to your concerns really soon.
LANSA has provided the easiest development effort for any platform of any tool I have used
Commenti: Visual LANSA allows us to substantially increase our development productivity and its ability to generate applications in multiple environments without new developer training allows us to "redeploy" developer resources from legacy technologies to modern functionality.
Aspetti positivi:
Business Rules can be defined by Business users, eliminating the need for developers to implement libraries or classes to handle the rules, and can be changed "on the fly" for a more agile application. The same skill set can be used for developing windows apps, web pages, and server side services. The developer does not need to learn how to use AWS,REST, HTML, CSS, JavaScript, SOAP, etc. They only need to understand how to use the Visual LANSA development environment and language to build full featured applications and services. When HTML5 was introduced, we were able to take advantage of the new functionality without a learning curve. Visual LANSA provides an integrated WYSIWYG for CSS definition. There is no need for creating the text files necessary, or writing the underlying definition code for these products as LANSA does this for you. In addition, LANSA provides a built-in end-user Application environment, the Visual LANSA Framework, This set of programs allow the developer to design the overall application, along with connectivity functionality, cross-program communications, and a uniform end-user experience. The Framework may be deployed in either windows or web/cloud (or both) without redefining the application! Time to market has been significantly reduced and user satisfaction has increased.
Aspetti negativi:
There is a "black-box" aspect to the product that can be a little frustrating when the execution environment does not act as expected. Also, the integration with external components and libraries can be somewhat obtuse. The biggest con is the limited number of developers currently using the product, which limits the amount of community interaction and "Tip" sharing. More developers would mean even more advances in the capabilities of the tool set.
