Framework Project Portfolio
1. (Framework Project) by Marcelo Salvador
Introduction: The project was created to build parts of a business tier for a retail
company.
Audience:
Business Executives
Information Workers
IT Managers
Project Goals:
The goal of the Framework Project was to create and test two assemblies. The
first assembly is a class library project called Foundation that contains interfaces and
base classes. The second assembly is a class library project called AppTypes where it
contains an entity, collection and exception classes used in various business processes.

/// <param name="value"></param>
void CopyTo(Object[] value);
/// <summary>
/// Sorts the collection using the IComparable interface of
each member of the collection.
/// </summary>
void Sort();
/// <summary>
/// Sorts the Collection based on the supplied IComparer.

}
Specification: Project containing Interfaces consolidating required properties
for abstractions. For example, IcompanyContact, Iaddress, IcountryPhone, IcontactInfo
and IcustomCollection. The ICustomCollection interface was provided as a contract to
guarantee that certain basic collection functionality would be available in the collection
classes written.

Two custom attributes DeveloperInfoAttribute and CustomDescription
Attribute were developed and used to further document the classes written. The
SupplierTypes enum is provided to insure that the type of each Supplier is limited to one
of the known types.
(Test Program allows viewing either the summary
results or the detail test output. Also, It will enable to
filter the output presenting results for a single section.)
