35. Cheque management System

36. Contents Cheque Received Module Cheque Monthly Revenue Monitoring Module Cheque Depositing Module Delayed Revenue Monitoring Module Management Reports Module Distributed Centralized

37. Cheque Received Module Cheques are received from the station Then the cheques are recorded in a system by using a scanner After a cheque is received system will provide storage number Manually verify whether cheque detail are correct, specially the total amount 123456789

38. CSNCheque NoBank Bank No Amount on Cheque Type of cheque Depositing bank details Customer Details Cheque Data Format CrossCash Deposit Name

39. Cheque Depositing Module Based on the bank a deposit form is filled, outputted automatically Cheques are deposited to the bank Cheque deposits are monitored Depositing Form Cheque Data(cheque no, bank no, branch no, amount, cheque date, deposit date) Total For Office use Confirmation on depositing EmployeeDate Hard copy

40. Monthly Revenue Monitoring Module At the end of a depositing cycle of a bank, bank statements are received at a central point(headquarters) Statements are scanned into the system All deposited cheques are verified and the monthly revenue is calculated Cheque NoDateAmount

41. Unrealized cheques brought forward for next month Cheque NoDateAmount

42. Delayed revenue Monitoring Module If the deposited cheques are not returned they are not added to the revenue and will be monitored at the next billing cycle

43. Management reports module Monthly revenue reports Unrealized cheques report Delayed revenue reports Daily number of cheques report

44. Data Location of each station Cheque depositing account details How to store the cheque in each station Depositing bank addresses at each location Policies – How long a dated cheque can be accepted? – The process of handling return cheques – Cheque revenue monitoring on monthly basis. If a cheque is deposited at the end of the month the maximum duration the revenue can be realized is one month – Special monitoring of large value cheques to see if deposited before the end of the month

45. Character Recognition System Instead of manual data entry a character recognition system could be used to directly scan cheques into the system, to increase efficiency of the system Also letters with regards to return cheques from banks can also be scanned into the system for recording and automatic un- realization.

55. Logic

56. Database A database is an organized collection of data for one or more purposes, usually in digital form. The data are typically organized to model relevant aspects of reality (for example, the availability of rooms in hotels), in a way that supports processes requiring this information (for example, finding a hotel with vacancies). This definition is very general, and is independent of the technology used. A database management system (DBMS) is a software package with computer programs that control the creation, maintenance, and use of a database. It allows organizations to conveniently develop databases for various applications by database administrators (DBAs) and other specialists. A database is an integrated collection of data records, files, and other objects. A DBMS allows different user application programs to concurrently access the same database.

57. Design a database Determine the purpose of your database - This helps prepare you for the remaining steps. Find and organize the information required - Gather all of the types of information you might want to record in the database, such as product name and order number. Divide the information into tables - Divide your information items into major entities or subjects, such as Products or Orders. Each subject then becomes a table. Turn information items into columns - Decide what information you want to store in each table. Each item becomes a field, and is displayed as a column in the table. For example, an Employees table might include fields such as Last Name and Hire Date. Specify primary keys - Choose each table’s primary key. The primary key is a column that is used to uniquely identify each row. An example might be Product ID or Order ID. Set up the table relationships - Look at each table and decide how the data in one table is related to the data in other tables. Add fields to tables or create new tables to clarify the relationships, as necessary. Refine your design - Analyze your design for errors. Create the tables and add a few records of sample data. See if you can get the results you want from your tables. Make adjustments to the design, as needed. Apply the normalization rules - Apply the data normalization rules to see if your tables are structured correctly. Make adjustments to the tables

58. Database Data example Database PIN Number(int(8), PRIMARY_KEY, NOT_NULL) Bank Account(int(10),NOT_NULL) Cheque No(int(6), NOT_NULL) Bank No(int(4), NOT_NULL) Amount(float(7), NOT_NULL) Cheque Date(datetime, NOT_NULL) Cheque Deposit Date(datetime, NOT_NULL) Storage No(int(4), NOT_NULL) Customer Name(varchar(50)) Description(varchar(500))

59. Implementation Process Create Database Design Interface Apply Logic

60. Creating Database MSSQL 2005 is used for this implementation.

61. Creating database conts…

63. Creating a table in database

65. Generating Storage No To generate Storage number we used another table,This table is managed to provide proper ID number for Cheque Master table that is created above.

66. Genstorageno table

67. Generate storage number Storage number is generated using stored procedure. Template Storage No: Letter(I Digit)+Year(2digits)+Sequence No(4digits) Eg:C110001

68. How to create a stored procedure Select Database  programmerbility  Stored procedure

69. Stored procedure for generate storage No CREATE PROCEDURE genStorageNumber @genStorage varchar (10) OUTPUT AS Begin Declare @ld_max dec(18,0),@ls_lchar int,@ld_max2 dec(18,0), @yr int set nocount on SELECT @ld_max=dbo.GenStorageNo.ref +1,@yr = dbo.GenStorageNo.gYear FROM dbo.GenStorageNo WHERE dbo.GenStorageNo.gYear = DATEPART(year, GETDATE()) ;

70. conts select @ls_lchar = 4 - len(@ld_max) select @genStorage = 'C' + SUBSTRING(ltrim(str(@yr)),3,2) + REPLICATE('0', @ls_lchar) + ltrim(str(@ld_max)) UPDATE dbo.GenStorageNo SET ref = ref +1 WHERE dbo.GenStorageNo.gYear = DATEPART(year, GETDATE()) ; End

71. Sql Procedure to Insert Cheque details ALTER PROCEDURE [dbo].[SaveChequeDetails] @CheckStorageNo varchar (15), @CheckNo varchar(15), @BankAccountNo varchar(15), @cAmount decimal, @ChequeDate datetime, @ChequeDipositDate datetime, @CustomerName varchar(100), @CustomerNICNo varchar(15), @Description varchar(500), @ID int output AS

72. conts Begin INSERT INTO tblChequeMaster (CheckStorageNo,CheckNo,BankAccountNo,cAmount,ChequeDate, ChequeDipositDate,CustomerName,CustomerNICNo,Description) VALUES (@CheckStorageNo,@CheckNo,@BankAccountNo,@cAmount,@ChequeDate, @ChequeDipositDate,@CustomerName,@CustomerNICNo,@Description); SELECT @ID=@@identity End

73. Sqlprocedure to display saved data ALTER PROCEDURE [dbo].[ShowChequeDetails] AS Begin SELECT CheckStorageNo,CheckNo,BankAccountNo,cAmount,ChequeDate, ChequeDipositDate,CustomerName,CustomerNICNo,Description FROM tblChequeMaster End

74. Interface for save cheque details

75. Code behind part(logic) Here the programming language selected is ASP.NET 2005 When you ready to save data(once you click on save button). The system is generated storage number. Next saved cheque details to database

76. Generate Storage number To generate store No you need to call stored procedure that you build above. First we need to build a connectionstring to communicate interface and database.

77. connectionstring to communicate interface and database private SqlConnection GetConnection(string connectionString) { SqlConnection connection = new SqlConnection(connectionString); connection.Open(); return connection; }

78. Call generate store no sp private string GenStorageNo() { SqlConnection connection = null; try { try { connection = GetConnection(ConfigurationManager.ConnectionStrings["Sample_ConnectionString"].ConnectionString); } catch { ClientScript.RegisterStartupScript(GetType(), "Message", " alert('The connection with the database can´t be established'); "); // return; }

79. conts SqlParameter[] arParms = new SqlParameter[1]; arParms[0] = new SqlParameter("@genStorage", SqlDbType.VarChar, 15); arParms[0].Direction = ParameterDirection.Output; SqlHelper.ExecuteNonQuery(connection, CommandType.StoredProcedure, "genStorageNumber", arParms); return arParms[0].Value.ToString(); } catch (Exception ex) { return ""; } finally { if (connection != null) connection.Dispose(); }

80. Save cheque details to database You need to call stored procedure that you build above.

81. Calling save sp private void SaveChequeData(string CheckStorageNo, string CheckNo, string BankAccountNo, decimal cAmount, DateTime ChequeDate, DateTime ChequeDipositDate, string CustomerName, string CustomerNICNo, string Description) { // SqlConnection that will be used to execute the sql commands SqlConnection connection = null; try { try { connection = GetConnection(ConfigurationManager.ConnectionStrings["Sample_ConnectionString"].ConnectionString); } catch { ClientScript.RegisterStartupScript(GetType(), "Message", " alert('The connection with the database can´t be established'); "); return; }

82. SqlParameter[] arParms = new SqlParameter[11]; //// @ProductID Input Parameter //// assign value = 1 arParms[0] = new SqlParameter("@ID", SqlDbType.Int); arParms[0].Direction = ParameterDirection.Output; // @ProductName Output Parameter arParms[1] = new SqlParameter("@CheckStorageNo", SqlDbType.VarChar, 20); arParms[1].Value = CheckStorageNo; // @UnitPrice Output Parameter arParms[2] = new SqlParameter("@BankAccountNo", SqlDbType.VarChar, 20); arParms[2].Value = BankAccountNo; // @QtyPerUnit Output Parameter arParms[3] = new SqlParameter("@cAmount", SqlDbType.Decimal); arParms[3].Value = cAmount;

83. conts arParms[4] = new SqlParameter("@ChequeDate", SqlDbType.DateTime); arParms[4].Value = ChequeDate; arParms[5] = new SqlParameter("@ChequeDipositDate", SqlDbType.DateTime); arParms[5].Value = ChequeDipositDate; arParms[6] = new SqlParameter("@CustomerName", SqlDbType.VarChar, 15); arParms[6].Value = CustomerName; arParms[7] = new SqlParameter("@CustomerNICNo", SqlDbType.VarChar, 15); arParms[7].Value = CustomerNICNo; arParms[8] = new SqlParameter("@Description", SqlDbType.VarChar, 500); arParms[8].Value = Description; arParms[9] = new SqlParameter("@CheckNo", SqlDbType.VarChar, 15); arParms[9].Value = CheckNo;

84. conts SqlHelper.ExecuteNonQuery(connection, CommandType.StoredProcedure, "SaveChequeDetails", arParms); if (arParms[0].Value.ToString() != null) { lblhelp.Text = "Great Success!, Record Saved."; string errMessage = " Record Saved Succsfully "; ClientScript.RegisterStartupScript(GetType(), "Message", " alert('" + errMessage + "'); "); } else { lblhelp.Text = "Please check, there is a mistake"; string errMessage = ""; errMessage = " Record Save Faile "; ClientScript.RegisterStartupScript(GetType(), "Message", " alert('" + errMessage + "'); "); }

85. conts catch (Exception ex) { lblhelp.Text = ex.Message + " " + "Please See Your IT Helper."; string errMessage = ""; for (Exception tempException = ex; tempException != null; tempException = tempException.InnerException) { errMessage = "Some Fields Empty. Unable to Save Data!"; ClientScript.RegisterStartupScript(GetType(), "Message", " alert('" + errMessage + "'); "); } } finally { if (connection != null) connection.Dispose(); }
