We chose to speak with Vakoms CEO Andriy Shevchyk about cross-platforms because of his level of experience, but also that Vakoms doesn’t necessarily have an initial preference for going Native or Cross-platform framework. The issue for Product Owners is to try to understand how credible each of the options is and where the tradeoffs lie if you decide to go with a cross-platform framework, over say iOS or Android. Their usage depends on a large number of parameters including cost, performance/UX, type of application(s) required, speed-to-market, required functionality etc. Here is a code example to get started:Įlse Dim db_file as FolderItem = ( 'vsqlitetest.And how we’ve used them to save time and money for our clients in the past.Įvery second new Software product development project I am involved with considers the use of a cross-platform framework. There is one more helper class from us, VSQLitePreparedStatement - to allow SQL queries with binding. You can find a working example here: 'V4RB/Examples/RBDB_way/VSlite'. To connect to Valentina Sqlite Server you should use our class VSQLiteDatabase as shown in the following code. We follow this API to allow you to migrate your existing Xojo App with SQLite local DB to our Valentina SQLite Server in no-time. Xojo provides its own universal Database API, which uses a common denominator model to provide support for different database servers and local SQLite files.

And of course it does much more work integrating SQLite DB where it is possible into Valentina Server features, such as SSL, SNMP, Reports, REST, … The first one for VCLIENT and the second one for LOCAL access.Ģ.2 Because of that we can write C++ code, totally the same to access both local and remote SQLite databases.Ģ.3 Valentina Server will use local-implementation to access SQLite engine.ģ) In the VCLIENT.dll we provide implementation of these 3 interfaces, which talk to remote Valentina ServerĤ) In the VKERNEL.dll we provide implementation of these 3 interfaces, as an alternative way to use SQLite engine, using our own C++ API.ĥ) In Valentina Server we add layer, which listens to the special ports for SQLite Server and use VKERNEL.dll → local-sqlite-implementation to work with sqlite engine. C++ Interfaces help us in few ways:Ģ.1 Allow to have few implementations. These interfaces wrap the native C API of SQLite engine. VShared/VSQL/Interfaces/VSQL_I_SqliteStatement.h
