   • Design Documentation in Software Engineering

     The design phase of software development deals with transforming the customer requirements as described in the SRS documents into a form implementable using a programming language. The software design process can be divided into the following three levels of phases design:

     • Interface Design
     • Architectural Design
     • Detailed Design

     Software Design Document:

     Software Design Document is a written document that provides a description of a software product in terms of architecture of software with various components with specified functionality.

     The design specification addresses different aspects of the design model and is completed as the designer refines his representation of the software. These design documents are written by software engineers/designers or project managers and further passed to the software development team to give them an overview of what needs to be built and how.

   • Design for Testability (DFT) in Software Testing

     Design for testability (DFT) is a procedure that is used to set the development process for maximum effectiveness under either a resource-limited or reliability-driven scheme. A resource-limited process uses a testing approach to get the results that a pre-release reliability goal has been met. This process views testing as a way to delete as many rough edges from a system as time or money permits. The testability is significant either to reduce cost in a reliability-driven process. and also to increase reliability in a resource-limited process.

     Importance of Design for Testability (DFT) in Software Testing:

     • Simplifies Diagnosis and Debugging: Debugging testable code is generally less difficult. The focus of DFT principles is on modularity and clarity, which helps developers identify and fix problems more quickly during testing and speeds up debugging cycles.

     I don't think that putting this in one class is a good idea. If you afraid that some function will repeat in 3 different class you can put it in some base class like below.

     Create abstract base class with common functions

     public abstract class ConnectionUtils<A,B,C> extends AsyncTask<A,B,C> { // put common functions here}

     Then create 3 separate class for each request

     public class RequestArticleList extends ConnectionUtils<Location, Void, String> { @Override protected String doInBackground(Location... userLocation) { return requestArticleList(userLocation); }}

     If you really want all this functionality in one class you can create callback interface

     public interface Callback<ResultType> { void onResult(ResultType result);}

     and then in each function create new Thread

     public void requestArticleList(final Callback<MyResult> callback) { new Thread(new Runnable() { @Override public void run() { // your code callback.onResult(result); } }).start();}

     Drawback is that its require switching to main thread before ui update.

   • Design Issues in Network Layer

     Network layer is majorly focused on getting packets from the source to the destination, routing error handling and congestion control.

     Before learning about design issues in the network layer, let’s learn about it’s various functions.

     Network layer design issues: The network layer comes with some design issues they are described as follows:

     1. Store and Forward packet switching: The host sends the packet to the nearest router. This packet is stored there until it has fully arrived once the link is fully processed by verifying the checksum then it is forwarded to the next router till it reaches the destination. This mechanism is called “Store and Forward packet switching.”

     2. Services provided to Transport Layer: Through the network/transport layer interface, the network layer transfers it’s services to the transport layer. These services are described below. But before providing these services to the transfer layer following goals must be kept in mind :-

     Based on the connections there are 2 types of services provided :

     3. Implementation of Connectionless Service: Packet are termed as “datagrams” and corresponding subnet as “datagram subnets”. When the message size that has to...

   • Network attached storage in DBMS

     With the phenomenal growth in digital data, particularly generated from multi-media and other enterprise application the need for high-performance storage solution at low cost has become extremely important. Network Attached Storage (NAS) devices are basically among the latest of storage devices being used for this purpose. These devices are in fact servers that basically do not provide any of the common server’s services, but simply allow the addition of storage of file sharing. NAS devices basically allow a vast amount of hard disk storage space to be added to a network and can make that space available to multiple servers without actually shutting down for maintenance and upgrades. These devices can reside anywhere on a LOCAL AREA NETWORK and may be combined in the different configuration. A single hardware device often called NAS box which basically act as an interface between the NAS system and network clients. These NAS systems do not require the monitor, keyboard or mouse. One or more disk or tape drives can be attached to many NAS system basically to increase the capacity. Clients basically connect to the NAS head rather than to...

   Why does a raid system need a storage area network (SAN)?

   • Many users of RAID system cannot use the capacity effectively because it has to be attached to a concept called Storage Area Network (SAN). In a SAN, online storage peripherals are configured as nodes on a high-speed network and can be attached and de-attached from servers in a very flexible manner.
