    <p>Imagine that I have one method like below that is using some strategies to create new products and persists them as a result in the Db. </p> <p>And everything happens as a part of a Unit of Work.</p> <p><strong>(My concern and)Question :</strong> My concern is it OK or preventable to pass the UnitOfWork instance as a parameter to strategies and Commit the changes in the root method? How can I avoid passing the UnitOfWork instance as a parameter to strategies but still make them work as a part of unit of work?</p> <p>(I don't like the fact that someone can call .Commit inside strategy implementations by mistake -which I do not want)</p> <pre><code>public void DoTheJob(CustomerRequest req) { var materialsPikcerStrategyFactory = new PickerStrategyFactory(); var productionStrategyFactory = new ProductionStrategyFactory(); var materialsPickerStrategy = materialsPikcerStrategyFactory.GetStrategy(req); var productionStrategy = productionStrategyFactory.GetStrategy(req); using (var uow = new UnitOfWorkFactory() ) { var materials = materialsPickerStrategy.PickMaterials(req, uow); var products = productionStrategy.CreateProductsWith(materials, uow); uow.Commit(); } } puplic abstract class MaterialsPickerStrategy { // Picks some material entities from Db and modifies some of its properties before usage public abstract ICollection&lt;Material&gt; PickMaterials(CustomerRequest req, IUnitOfWorkFactory uow); } public abstract class ProductionStrategy { // Gets the materials and creates some new instances by ADD'ing them to the repository public abstract void CreateProductsWith (ICollection&lt;Material&gt; materials, IUnitOfWorkFactory uow); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
