Data/Document Work Flow is a set of C# libraries to build simple cross-platform IS:

• DataWF.Common - .NETStandard collections, reflections, io and networks helpers
• DataWF.Data - .NETStandard Cross RDBMS ORM
• DataWF.Gui - Xwt based desktop UI
• DataWF.Data.Gui - Database desktop UI
• DataWF.Module.Common - Common models
• DataWF.Module.Flow - Document Workflow models
• DataWF.Module.CommonGui - Users Administator UI
• DataWF.Mudule.FlowGui - Document Workflow UI

Note: most of DataWF UI libraries is in developing stage and not ready for production!

Implement RPC/REST Server with Desktop/Web UI. Port to Avalonia UI

ORM based on ADO.NET drivers. Not use EF.

Features: Code-first, Relational data managment, Formatting DDL and DML, Caching large tables

Cover basic database objects: Schema, Table, View, Column, Constraints(Primary and Foreign Key), Index, Stored Procedure.

Support several RDBMS(simply extendable):

• MSSQL
• MySql
• Oracle
• Postgress
• Sqlite

Limitation/Overhead:

• One column Primary Key
• System columns: Create date, Stamp date, Access binary, Item Type identifier

Note: used beta version of ODP.NET for .netstandard compatibility

Model example:

[Table("employer_table")]
public class Employer : DBItem
{
    public static DBTable<Employer> DBTable { get { return DBService.GetTable<Employer>(); } }

    public Employer() { Build(DBTable); }

    [Column("id", Keys = DBColumnKeys.Primary)]
    public int? Id {  get { return GetProperty<int?>(); }  set { SetProperty(value); } }

    [Column("inn", 20, Keys = DBColumnKeys.Code), Index("employerinn", true)]
    public string INN {  get { return GetProperty<string>(); }  set { SetProperty(value); } }

    [Column("name", 200, Keys = DBColumnKeys.Culture)]
    public override string Name {  get { return GetName(nameof(Name)); }  set { SetName(nameof(Name), value); } }

    [Column("positionid")]
    public int? PositionId { get { return GetProperty<int?>(); } set { SetProperty(value); } }

    [Reference(nameof(PositionId))]
    public Position Position
    {
        get { return GetPropertyReference<Position>(); }
        set { SetPropertyReference(value); }
    }

    [Column("typeid", Keys = DBColumnKeys.Type, Default = "1")]
    public EmployerType? Type {  get { return GetProperty<EmployerType?>(); }  set { SetProperty(value); } }
}

Connection example:

var connection = new DBConnection("test") { System = DBSystem.SQLite, DataBase = "test.sqlite" };
var qresult = connection.ExecuteQResult( $"select * from {SomeTableName}");

Cross Platform Desktop UI, based on Xwt. Provide several widgets to build data navigation application

Main widgets:

• LayoutList - universal widget, can be used like list view, tree view or property view. Support sorting, grouping, filtering and can construct from reflection
• Toolsbar - buttons container
• GroupBox - widget layout container
• DockBox - dock panel manager
• ToolWindow - helper window

Note: Move UI from WinForm/Gtk# to Xwt is not compleate and little bugly.

• Database Administrator
• Database Export utilite
• Query Builder(not compleate)
• Report engeene(planed)

Common Models:

• Group & Permission
• User & User Group
• User Log
• Reference Book
• Scheduler

WorkFlow Models:

• Work & Stage
• Template & Attribute
• Document & Relating Data

• User&Group Administrator

• Workflow Administrator
• Document Editor (Create, Edit, Send document throw the flow);
