Starter? Quick-Win required? h2 embedded database in java

Optimal job for newcomers as freelancer, but with good experience on h2database! we require a simple application to start a embedded h2database with: - main method - additional methods each: ... - pure insert, select example ... - xml insert, select example ... - json insert, select example ... - spatial data insert and select examples ... - directed graph (nodes) insert and select - encrypted database files in a configurable (java constant) folder, which is as default [login to view URL] - backup creation of database files on starting by ensuring transaction log is written, with rolling file naming - ensure clean close/disconnect of h2database with a java exit hook - strict mode - ensure only one instance is running, or ensure database files are able to handle concurrent connects - data has to be defined in a class and afterwards inserted to table with some examples most features are well documented here: [login to view URL] [login to view URL] We require this prototype to test. Start a simple UI to display app is running. Preferably JavaFX but Swing is also okay. - no special logic required - no special table structure required, only generated ID, and the task specific table structure with some sample data (e.g. on spacial, to have a spacial table + some example values inserted for a corresponding java spatial class) - No framework required (spring or something, if you think you require, let us know) - no UI or chart required for the directed graph, only provide coded sample data and persist it you deliver the code, which basically has - a main(), - main() is using your implemented classes, no custom code in main() - opens a splash screen or a UI on starting to show something is going on Delivery Milestones: MS1: run embedded h2database with maven run and display in a dialog/UI/splashscreen the started database status: - encrypted database files in a configurable (java constant) folder, which is as default [login to view URL] - backup creation of database files on starting by ensuring transaction log is written, with rolling file naming - ensure clean close/disconnect of h2database with a java exit hook - strict mode - ensure only one instance is running, or ensure database files are able to handle concurrent connects MS2: all other features delivery? - in our git (will be shared after award) - as java source delivery - clean module and lib dependencies - maven (dependencies are all managed there) - required libs need PRIOR confirm to be accepted! - JDK17 compatible your bid? you provide estimate per milestone, we may discuss about requirements we confirm, you implement Budget? we do not disclose, place your best bid to get considered Hint: be ensured, your bid will be checked by java developers. This is a test task for integrating you into an ongoing project. So dear overseller and sales manager. We know the complexity of the task, and thus we also know if your bid is realistic. Be aware we will only hire the freelancers/companies wo play open and honest on the bid Outlook: we will award you all changes for the next steps of the prototype and the requirements we implement We will require for this a NDA!
