4. Nivelul de accesare date (Data Access Tier)

Rolul acestui nivel este de a incapsula toate cererile la baza de date. Un prim avantaj este incapsulareaacestor cereri intr-un singur loc si deci o mai mare usurinta in mentenanta.

Un alt avantaj apare in momentul schimbarii bazei de date folosite, de exemplu trecerea pe Oracle nu va

necesita decat rescrierea metodelor din DAL restul codului ramanand perfect functional.

Cod sursa reprezentativ

Path = DAL/Products.cs – Metode prin care se pot selecta, edita, adauga produse.namespace DAL

{

public static class Products

{

public static ProductsDataSet.vwProductsDataTable GetProducts(string categoryID, string product)

{

string spName = "spProducts_GetProducts";

Database db = DatabaseFactory.CreateDatabase();

DbCommand dbCommand = db.GetStoredProcCommand(spName);

db.AddInParameter(dbCommand, "CategoryID", DbType.Int32,

Empty2NullConvert.ToInt32(categoryID));

db.AddInParameter(dbCommand, "Product", DbType.String,

Empty2NullConvert.ToString(product));

ProductsDataSet dataSet = new ProductsDataSet();

db.LoadDataSet(dbCommand, dataSet, dataSet.vwProducts.TableName);

return dataSet.vwProducts;

}





public static ProductsDataSet.vwProductsDataTable GetProduct(int productID)

{

string sqlCommand = "SELECT * FROM vwProducts Where ProductID = @ProductID";


DbCommand dbCommand = db.GetSqlStringCommand(sqlCommand);

db.AddInParameter(dbCommand, "ProductID", DbType.Int32, productID);

ProductsDataSet dataSet = new ProductsDataSet();

db.LoadDataSet(dbCommand, dataSet, dataSet.vwProducts.TableName);

return dataSet.vwProducts;

}

public static void SetImage(string productID, byte[] imageContent)

{

string sqlCommand = "UPDATE [dbo].[Products] SET [Image] = @Image WHERE ProductID =

@ProductID";

Database db = DatabaseFactory.CreateDatabase();DbCommand dbCommand = db.GetSqlStringCommand(sqlCommand);

db.AddInParameter(dbCommand, "Image", DbType.Binary, imageContent);


db.ExecuteNonQuery(dbCommand);

}

public static byte[] GetImage(string productID)

{

string sqlCommand = "SELECT [Image] FROM [dbo].[Products] WHERE [ProductID] =

@ProductID";


DbCommand dbCommand = db.GetSqlStringCommand(sqlCommand);


object imageContent = db.ExecuteScalar(dbCommand);

return imageContent != DBNull.Value ? (byte[])imageContent : null;

}

public static int AddSetProduct(string productID, string product, string code, string producerID, string

description, string categoryID, string quantity, string price, string priceCurrencyID)

{

string spName = "spProducts_SetProduct";


DbCommand dbCommand = db.GetStoredProcCommand(spName);

db.AddInParameter(dbCommand, "ProductID", DbType.Int32,

Empty2NullConvert.ToInt32(productID));

db.AddInParameter(dbCommand, "Product", DbType.String,

Empty2NullConvert.ToString(product));

db.AddInParameter(dbCommand, "Code", DbType.String, Empty2NullConvert.ToString(code));

db.AddInParameter(dbCommand, "ProducerID", DbType.Int16,

Empty2NullConvert.ToInt32(producerID));

db.AddInParameter(dbCommand, "Description", DbType.String,

Empty2NullConvert.ToString(description));

db.AddInParameter(dbCommand, "CategoryID", DbType.Int16,

return (int)db.ExecuteScalar(dbCommand);

}

}}

5. Nivelul de logica (Business Tier)Un alt pas foarte important in arhitectura pe n-nivele este de a separa logica aplicatiei de logica interfetei.

Ideea este de a porta aceesi logica cat mai usor in diferite, de exemplu de a porta aceleshi clase de BLL de

la o aplicatie web la una client cu efort cat mai mic.

5.1 Proiectul BLL

BLL – Business Logic Layer In general toate entitatile din db sunt mapate prin clase din BLL. Deasemnea tot in BLL intalnim si clasa

ShoppingCart ce acopera functionalitatea cosului de cumparaturi.

In CurrentUser se stocheaza toate informatiile referitoare la utilizatorul logat.

Cod sursa reprezentativ Path = BLL/ShoppingCart.cs

namespace BLL

{

public class ShoppingCart

{

public static Hashtable CartTable

{

get

{

if (HttpContext.Current.Session["CartTable"] == null)

HttpContext.Current.Session["CartTable"] = new Hashtable();

return (Hashtable)HttpContext.Current.Session["CartTable"];}

set

{

HttpContext.Current.Session["CartTable"] = value;





}

}

public static DataTable ComputedTable

{

get

{

DataTable myDataTable = new DataTable();DataColumn myColumn;

DataRow myRow;

myColumn = new DataColumn();

myColumn.DataType = System.Type.GetType("System.Int32");

myColumn.ColumnName = "ProductID";

myDataTable.Columns.Add(myColumn);


myColumn.DataType = Type.GetType("System.String");

myColumn.ColumnName = "Product";


myColumn = new DataColumn ( );

myColumn.DataType = System.Type.GetType ( "System.Int32" );

myColumn.ColumnName = "Quantity";

myDataTable.Columns.Add ( myColumn );


myColumn.DataType = System.Type.GetType("System.Double");

myColumn.ColumnName = "Price";



myColumn.DataType = Type.GetType("System.String");

myColumn.ColumnName = "PriceCurrency";myDataTable.Columns.Add(myColumn);

CartItem item;

foreach (int key in ShoppingCart.CartTable.Keys)

{

item = (CartItem)ShoppingCart.CartTable[key];

myRow = myDataTable.NewRow();

myRow["ProductID"] = key;

myRow["Product"] = item.Product;

myRow["Quantity"] = item.Quantity;

myRow["Price"] = item.Quantity * item.Price;

myRow["PriceCurrency"] = item.PriceCurrency;myDataTable.Rows.Add(myRow);

}

return myDataTable;

}

}

public static double Total

{

get

{

double total = 0;

foreach (CartItem item in ShoppingCart.CartTable.Values)

total += item.Quantity * item.Price;

return total;





}

}

public static void AddProduct(int productID, string product, double price, string priceCurrency)

{

if (CartTable.ContainsKey(productID))

{

((CartItem)CartTable[productID]).Quantity += 1;}

else

CartTable[productID] = new CartItem(product, 1, price, priceCurrency);

}

public static void RemoveProduct(int productID)

{

if (CartTable.ContainsKey(productID))

CartTable.Remove(productID);

}

public static string GetOrderItemsXml()

{XmlDocument xmlDoc = new XmlDocument();

XmlElement rootElement = xmlDoc.CreateElement("order");

xmlDoc.AppendChild(rootElement);

XmlElement itemElement;

XmlElement productIDElement;

XmlElement quantityElement;

string xml = string.Empty;

foreach (int productID in CartTable.Keys)

{

itemElement = xmlDoc.CreateElement("item");

productIDElement = xmlDoc.CreateElement("productID");quantityElement = xmlDoc.CreateElement("quantity");

productIDElement.InnerText = productID.ToString();

quantityElement.InnerText = ((CartItem)CartTable[productID]).Quantity.ToString();

itemElement.AppendChild(productIDElement);

itemElement.AppendChild(quantityElement);

rootElement.AppendChild(itemElement);

}

return xmlDoc.OuterXml;

}

}

}

Path = BLL/CurrentUser.csnamespace BLL

{

public class CurrentUser

{

private CurrentUser() { }

public static bool IsAuthenticated

{

get { return (HttpContext.Current.Session["SiteUserID"] != null); }

}

public static int ID

{

get





{

if (HttpContext.Current.Session["SiteUserID"] != null)

return Convert.ToInt32(HttpContext.Current.Session["SiteUserID"]);

else

return 0;

}

set

{HttpContext.Current.Session["SiteUserID"] = value;

}

}

public static string Name

{

get

{

if (HttpContext.Current.Session["SiteUserName"] != null)

return HttpContext.Current.Session["SiteUserName"].ToString();

else

return string.Empty;

}set

{

HttpContext.Current.Session["SiteUserName"] = value;

}

}

public static string Role

{

get

{

if (HttpContext.Current.Session["SiteUserRole"] != null)

return HttpContext.Current.Session["SiteUserRole"].ToString();

elsereturn string.Empty;

}

set

{

HttpContext.Current.Session["SiteUserRole"] = value;

}

}

public static bool IsAdmin

{

get

{

return ((CurrentUser.IsAuthenticated) && (CurrentUser.Role.Equals("Administrators")));}

}

}

}

5.2 Proiectul Info

Proiectul Info contine clase ce au numai proprietati fara metode. Fisierele .xsd sunt dataseturi care

mapeaza coloanele tabelelor sau vederilor din baza de date.





Path = BLL/ProductFilter.cs[Serializable()]

public class ProductFilter

{

public string CategoryID;public string Product;

}

Path = BLL/CartItem.cspublic class CartItem

{

public string Product;

public int Quantity;

public double Price;

public string PriceCurrency;

public CartItem(string product, int quantity, double price, string priceCurrency){

this.Product = product;

this.Quantity = quantity;

this.Price = price;





this.PriceCurrency = priceCurrency;

}

}

5.3 Proiect Library

Proiectul Library contine acele clase ce pot fi reutilizate in diferite alte proiecte, clase ce nu sunt strans

legate de logica aplicatie curente : delegate-uri, interfete. Clasa Empty2NullConvert are rolul de a converti

string-uri in alte tipuri de date cu conditia ca empty devine null, este foarte utila in trimitea datelor catre

db.

Path = Library/CommonTypes/EventHandlers.csnamespace Library.CommonTypes

{

public class IdEventArgs : EventArgs

{public int ID;

public IdEventArgs(int id)

{

this.ID = id;

}

}

public delegate void IdEventHandler(object sender, IdEventArgs e);

}

Path = Library/ CommonTypes/Interfaces.csnamespace Library.CommonTypes

{

public interface IDataBind

{

void DataBind();

}

public interface IDetailsView : IDataBind

{

string DataSourceID { get; set; }

}

public interface IInitEvents

{





void InitEvents();

}

public interface IItemCommand

{

event IdEventHandler ItemCommand;

}

public interface IListControl : IDataBind

{

int PageIndex { get; set; }

int PageSize { get; set; }

}

}

Path = Library/Convertion/Empty2NullConvert.csnamespace Library.Convertion

{

public class Empty2NullConvert

{

private Empty2NullConvert() {}

public static object ToDateTime(object objectValue)

{

if (objectValue == null)

return null;

else

{

if (IsEmptyString(objectValue)) return null;

try

{

return Convert.ToDateTime(objectValue);

}catch(Exception)

{

return null;

}

}

}

public static object ToInt32(object objectValue)

{

if (objectValue == null)

return null;

else

{if (IsEmptyString(objectValue)) return null;

try

{

return Convert.ToInt32(objectValue);

}

catch(Exception)

{

return null;

}

}

}

6 Nivelul de Prezentare (Presentation GUI & Presentation Logic)





Utilizatorii sistemului sunt de 3 tipuri cumparatori, operatori si administratori.

Operatorii lucreaza pe backoffice sunt cei care aproba cumparaturile si trimiterea lor catre destinatie.

Administratori sunt cei care pot edita/stege/ produse produse,categorii etc.

6.1 Cazuri de utilizare Cumparator

6.1.1 Login

DescriereSistemul poate fi folosit si de utilizatori neautentificati. Dar pentru o mai mare usurinta la cumparaturi, in

sensul ca datele de trimitere cosului vor fi completate automat, cumparatori se pot autentifica la sistem.

Autentificare duce si la o mai buna evidenta a cumparaturilor aceleashi persoane.

Imagine din aplicatie

Cod sursa reprezentativ Path = /Front/Login.aspx

<asp:Login ID="lgnLogin" runat="server" DestinationPageUrl="~/Default.aspx" FailureText="Invalid

credentials" >

</asp:Login>

void lgnLogin_Authenticate(object sender, AuthenticateEventArgs e)

{

UsersDataSet.vwUsersRow userRow = Users.GetUser(lgnLogin.UserName, lgnLogin.Password);

if (userRow != null)

{

e.Authenticated = true;

CurrentUser.ID = userRow.UserID;

CurrentUser.Name = userRow.Username;

CurrentUser.Role = userRow.Group;

}

elsee.Authenticated = false;

}

6.1.2 Inregistrare

DescriereInregistrarea se face completand un formular cu datele personale.






Cod sursa reprezentativ Path = /Front/UC/Register.ascx

void btnRegister_Click(object sender, EventArgs e){

int userID = Users.AddCustomerUser(txtUsername.Text,txtPassword.Text,txtLastName.Text,txtFirstName.Text,txtCounty.Text,txtTown.Text,txtAddress.Text,txtPhone.Text,txtEmail.Text);

if (userID != 0)

{CurrentUser.ID = userID;CurrentUser.Name = txtPassword.Text;CurrentUser.Role = "Customers";Response.Redirect("~/default.aspx");

}}





6.1.3 Cautare produse

DescriereCautarea produselor se poate face in doua moduri : dupa categoriile din care acestea fac parte sau dupa

nume produs sau un termen folosit in descrierea acestuia.

6.1.4 Adaugare produs in cos

DescriereOdata gasite produsele dorite acestea se pot adauga in cos in vederea cumparari lor.

Un produs poate fi vizualizat in detaliu dand click pe imaginea acestuia.

Produsul se poate aduga in cos apasand pe inconita Comand.

In dreapta pagii se poate vedea cosul de cumparaturii cu toate produsele adaugate.

Cosul de cumparaturi si poate edita astfel se poate renunta la anumite produse selectate.

statusul comenzi. Comenzile ale caror date nu sunt reale vor fi respinse. Odata vizualizata comanda,

comparatorul este sunat pentru confirmarea comenzii si pentru a fi informat de data sosirii comenzi.Comenzile ce trebuiesc analizate apar cu starea Created. Comenzile trimise catre client apar cu starea

Shipped. Comenzile trimise si platite apar la starea Payed. Comenzile primite si respinse de client apar la

starea Returned.
