Where and Having DIFFER?When working with more ADVANCED SQL it can be unclear when it makes sense to use a WHERE versus a HAVING clause.Though it appears that both clauses do the same thing, they do it in different ways. In fact, their functions complement each other.A WHERE clause is used is filter records from a result. The filter occurs before any groupings are made.A HAVING clause is used to filter values from a group.Before we go any further let’s review the format of an SQL Statement. It isSELECTFROMWHEREGROUP BYHAVINGTo help keep things straight I like to think of the order of execution of SQL statements as from top to bottom. That means the WHERE clause is first applied to the result and then, the remaining rows summarized according to the GROUP BY.WHERE clauseThe WHERE clause is used to filer rows from a results. For instanceSELECT COUNT(SalesOrderID)FROM Sales.SalesOrderDetailReturns 121,317 as the count, whereas, the querySELECT COUNT(SalesOrderID)FROM Sales.SalesOrderDetailWHERE UnitPrice > 200Returns 48,159 as the count. This is because the WHERE clause filters out the 73,158 SalesOrderDetails whose UnitPrice is less than or equal to 200 from the results.HAVING ClauseThe HAVING clause is used to filter values in a GROUP BY. You can use them to filter out groups such asSELECT SalesOrderID, SUM(UnitPrice * OrderQty) AS TotalPriceFROM Sales.SalesOrderDetailGROUP BY SalesOrderIDHAVING SalesOrderID > 50000But their true power lies in their ability to compare and filter based on aggregate function results. For instance, you can select all orders totaling more than $10,000SELECT SalesOrderID, SUM(UnitPrice * OrderQty) AS TotalPriceFROM Sales.SalesOrderDetailGROUP BY SalesOrderIDHAVING SUM(UnitPrice * OrderQty) > 10000Since the WHERE clause’s visibility is one row at a time, there isn’t a way for it to evaluate the SUM across all SalesOrderID’s. The HAVING clause is evaluated after the grouping is created.Combining the two: WHERE and HAVINGWhen SQL statements have both a WHERE clause and HAVING clause, keep in mind the WHERE clause is applied first, then the results grouped, and finally the groups filtered according to the HAVING clause.In many CASES you can place the WHERE condition in the HAVING clause, such asSELECT SalesOrderID, SUM(UnitPrice * OrderQty) AS TotalPriceFROM Sales.SalesOrderDetailGROUP BY SalesOrderIDHAVING SUM(UnitPrice * OrderQty) > 10000 AND SalesOrderID > 50000VersusSELECT SalesOrderID, SUM(UnitPrice * OrderQty) AS TotalPriceFROM Sales.SalesOrderDetailWHERE SalesOrderID > 50000GROUP BY SalesOrderIDHAVING SUM(UnitPrice * OrderQty) > 10000If you can put condition from the where clause in the having clause then why even worry about the WHERE? Can I just use this query?SELECT SalesOrderID, SUM(UnitPrice * OrderQty) AS TotalPriceFROM Sales.SalesOrderDetailGROUP BY SalesOrderIDHAVING SUM(UnitPrice * OrderQty) > 10000 AND LineTotal > 10Actually that query generates an error. The column LineTotal is not part of the group by field list nor the result of an aggregate total.To be valid the having clause can only compare results of aggregated functions or column part of the group by.To be valid the query has to be rewritten asSELECT SalesOrderID, SUM(UnitPrice * OrderQty) AS TotalPriceFROM Sales.SalesOrderDetailWHERE LineTotal > 100GROUP BY SalesOrderIDHAVING SUM(UnitPrice * OrderQty) > 10000To summarize the difference between WHERE and HAVING:WHERE is used to filter records before any groupings take place.HAVING is used to filter values after they have been groups. Only columns or expression in the group can be included in the HAVING clause’s conditions..

below are some features that are found in C++, not found in C, but still have nothing to do with Object Oriented Programming.CastsIn C, if you want to cast an int to a long int, for example, you'd use int i=0; long l = (long) i; In C++, you can use a function-like call to make the cast. long l = long(i); It's easier to read. Since it's possible to create functions to perform casts involving user-defined types, this makes all the casts look consistent. For example, you may have a user-defined type -- complex numbers. You have a function that accepts an integer and casts it to a complex number: 1 --> 1 + 0i (real part is 1 and imaginary part is 0) Suppose your function call is named 'complex', then it may look like: Complex x; int i=1; x = complex(i); Flexible DeclarationsIn C, all var declarations within a SCOPE occur at the beginning of that scope. Thus, all global declartions MUST appear before any functions, and any local declarations must be made before any executable statements.C++, on the other hand, allows you to mix data declarations with functions and executable statements. E.g. In C,void makeit(void) { float i; char *cp; /* imagine 2000 lines of code here */ /* allocate 100 bytes for cp */ cp = malloc(100); /* 1st use of cp */ for (i=0; i<100; ++i) /* 1st use of i */ { /* do something */ } /* more code */ } In C++, void makeit(void) { // 2000 lines of code char *cp = new char[100]; for (int i=1; i<10; i++) { } } 'struct' and 'union' TagsIn C, we would have this segment: struct foo {int a; float b;} struct foo f; This declares a struct with the tag name 'foo' and then creates an instance of foo named f. Notice when you DECLARE var of that struct, you have to say 'struct foo'. In C++, struct and union tags are considered to be type name, just as if they had been declared by the 'typedef' statement. struct foo {int a; float b;} foo f; which is EQUIVALENT to the following in C: typedef struct { int a; float b; } foo; foo f;

vel Programming LanguagesHigh-level programming languages, while simple compared to HUMAN languages, are more complex than the languages the computer actually understands, called machine languages. Each different type of CPU has its own unique machine language.Lying between machine languages and high-level languages are languages called assembly languages. Assembly languages are similar to machine languages, but they are much easier to program in because they allow a programmer to substitute NAMES for numbers. Machine languages consist of numbers only.Lying above high-level languages are languages called fourth-generation languages (usually ABBREVIATED 4GL). 4GLs are far removed from machine languages and represent the class of computer languages closest to human languages.

sive testing ALSO known as incremental testing is used to test MODULES one after the other. When an application with a hierarchy such as parent-child module is being tested, the related modules would need to be tested first.This progressive approach testing method has three approaches:Top-down ApproachBottom-up ApproachHybrid ApproachRegression testing: Testing your software application when it undergoes a code change to ENSURE that the new code has not affected other parts of the software.

distributed systems RESEARCH area replication is mainly used to provide fault tolerance. The entity being replicated is a process. Two replication strategies have been used in distributed systems: Active and Passive replicationIn active replication each client request is processed by all the servers. Active Replication was first introduced by Leslie Lamport under the name state machine replication. This requires that the process hosted by the servers is deterministic. Deterministic means that, given the same initial state and a request sequence, all processes will produce the same response sequence and end up in the same final state. In ORDER to make all the servers receive the same sequence of operations, an atomic broadcast protocol must be used. An atomic broadcast protocol guarantees that either all the servers receive a message or none, plus that they all receive messages in the same order. The big disadvantage for active replication is that in practice most of the real world servers are non‐deterministic. Still active replication is the preferable choice when dealing with real TIME systems that require QUICK response even under the presence of faults or with systems that must handle byzantine faults.In passive replication there is only one SERVER (called primary) that processes client requests. After processing a request, the primary server updates the state on the other (backup) servers and sends back the response to the client. If the primary server fails, one of the backup servers takes its place. Passive replication may be used even for non‐deterministic processes. The disadvantage of passive replication compared to active is that in case of failure the response is delayed

gesCentralization of control: access, resources and integrity of the data are controlled by the dedicated server so that a program or unauthorized client cannot damage the system. This centralization also facilitates task of updating data or other resources (better than the networks P2P).Scalability: You can increase the capacity of clients and servers separately. Any element can be increased (or enhanced) at any time, or you can add new nodes to the network (clients or servers).Easy maintenance: distribute the roles and responsibilities to several standalone computers, you can replace, REPAIR, upgrade, or even move a server, while  customers will not be affected by that change (or minimally affect). This independence of the changes is also known as encapsulation.DisadvantagesTraffic congestion has always been a problem in the paradigm of C / S. When a large number of simultaneous clients send requests to the same server might cause many problems for this (to more customers, more problems for the server). On the contrary, P2P networks each node in the network server also makes more nodes, the better bandwidth you have.The paradigm of C / S Classic does not have the robustness of a network P2P. When a server is down, customer requests cannot be MET. In most part, P2P networks resources are usually distributed ACROSS multiple nodes of the network. Although some out or abandon download, others may still end up getting data download on rest of the nodes in the network.The software and hardware of a server are usually very decisive. A regular computer hardware staff may not be able to serve a certain number of customers. Usually you need specific software and hardware, especially on the server side, to meet the work . Of course, this will increase the cost.The client does not have the resources that may exist on the server. For example, if the application is a Web, we cannot WRITE the hard disk of the client or print directly on printers without taking before the print preview WINDOW of the browser.hope this will help you.

t Remaining Time SchedulingShortest remaining time (SRT) schedulingShortest remaining time scheduling is the preemptive counter part of SJF and is useful in time sharing system. In SRT, process with the smallest estimated run time to completion is run next, in SJF once a job begin executing, it runs to completion. In SRT a running process may be preempted by a user process with a shorter estimated run time.Consider an example, where three processes arrived in the order P1, P2, P3 at the time mentioned below, and then the average waiting time USING SJF scheduling algorithm will be calculated as:process CPU Burst Time Time of Arrivalp1 10 0p2 5 1p3 2 2shortest remaining time schedulingshortest remaining time schedulingIn this, the CPU will be taken away from the currently executing process whenever a process will less CPU burst time.As shown in figure, the time when P2 arrives P1 needs 9 millisecond more to finish. As B’s cpu burst in 5 millisecond < 9 millisecond, therefore, P1’s execution will be preempted and P2 will be EXECUTED but against as P3 arrives P2’s execution needs 3 more millisecond where as P3 needs only 2 millisecond to EXECUTE, thus P3 TAKES over P2 and so on.Waiting time for P1 = 0+ (8-1) = 7 millisecondWaiting time for P2 = 1+ (4-2) = 3 millisecondWaiting time for P3 = 2 millisecondAverage waiting time = (7+3+2) / 3 = 4 millisecond

uter fields, computer architecture is a set of rules and ways that explain the functionality, organization and implementation of computer systems. Some definitions of computer architecture and organization describes the capabilities and programming model of a computer but not a particular implementation.The term computer is used to describe a device made up of a combination of electronic and electro-mechanical (electronic and mechanical) components.By itself, a computer has no intelligence and is referred to as hardware, which means simply the physical equipment. A computer can`t be used until it is CONNECTED to other parts of a computer system and software is installed.Source: www.123rf.comThe design, arrangement , construction or organization of the different parts of a computer system is known as Computer Architecture. It is the conceptual design and fundamental operational STRUCTURE of a computer system.It is a framework and functional description of REQUIREMENTS and design implementations for the various parts of a computer, focusing largely on the way by which the Central Processing Unit (CPU) performs internally and accesses addresses in memory.It may also be defined as the science and art of selecting, interconnecting hardware components to create computers to meet functional performance and cost.HISTORYThe first document of Computer Architecture was a correspondence between Charles Babbage and Ada Lovelace, that describes the analytical engine. Here is the example of other early important machines: John Von Neumann and Alan Turing.Computer architecture is the art of determining the needs of the user of a structure and then designing to meet those needs as effectively as possible with economic status and as well as the technological constraints. In ANCIENT period, computer architectures were designed and prepared on the paper and then, directly built into the final hardware form. Later, in today`s computer architecture, prototypes were physically built in the form of transistor logic (TTL) computer such as the prototypes of the 6800 and the PA-RISC tested, and tweaked before committing to the final hardware form. (Wikipedia and Quora)LAYEROF COMPUTER ARCHITECTUREUnder the Computer architecture, it consists of 6 layers. They are as follows:Electrical and electronic component levelDigital logic levelMicro programmed levelMachine levelSystem software levelApplication program levelElectrical and Electronic component levelAlmost all the modern computer devices are built from a simple electric component such as transistors, capacitors, a resistor which works on suitable power supplies.Digital logical levelAll the basic operations of the machine are provided at this level. The basic element at this level can store, manipulate and transmit data in the simple binary form. These digital logic elements are called gates which are normally constructed or made from a small number of transistors and other electronic components.The standard digital logic devices are combined together to form computer processor or computer memories.Micro program levelIn this level, a sequence of microinstruction constitutes the microprogramming, which we called firmware, which is permanently stored in ROM. At the time, when the computer was made without microprogram level processor, it was built from a combination of a digital logic component.The use of micro programmed level enables a manufacturer to produce a family of processors all of which process the same set of machine instruction at the machine level which differs in terms of construction and speed.Machine levelSeveral hardware levels are presented in machine level. These are the basic elements of the computer. They are processor, input/output device, main memory, auxiliary storage, etc.System software levelThe program that directs the internal operation of a computer system is called system software.Application software levelThe program directs the computer to solve user-oriented problems are called application software.According to the Computer architecture, it has three SUBCATEGORIES:Instruction set ArchitectureMicro-architectureSystem Design

ration test, also KNOWN as a pen test, is a simulated cyberattack against your computer system to check for EXPLOITABLE vulnerabilities. In the context of web application security, penetration testing is commonly used to augment a web application firewall (WAF). Pen testing can involve the attempted BREACHING of any number of application SYSTEMS, (e.g., application protocol interfaces (APIs), frontend/backend servers) to uncover vulnerabilities, such as unsanitized inputs that are susceptible to code injection attacks.
