    REST Dataware Componentes

    REST Dataware Componentes

    Componentes estilo DB para uso em Servidores REST

    New version stable. The proposal was fulfilled. REST DW was created to facilitate the creation of CRUDs in the same model that we created applications for Client / Server Database. Today to be able to write data in a Bank via WebService is very complex for simple operations, making scheduling of simple screens time-consuming. With REST DW, you no longer have to worry about creating SQL Insertion, Deletion, Read and Execution methods via Webservice; Simply add a RESTDataBase connection component and add a RESTClientSQL component that will already have your SQL solution fully functional as it did back in the day and with all the power of modern REST / JSON technology with data compression and everything the language can offer, Use it, have fun, and need support.
