C Algorithms – Graph Theory

Exforsys
The graph theory refers to the study of graphs. A graph is a mathematical object that captures the notion of connection. For example, you want to connect two or more dots that could be considered a graph. Leonhard Euler is the inventor of graph theory, as he tried to solve the known problem of the Seven Bridges of Konigsberg.The townspeople supposedly posed the question “Is it possible to take a walk through town, crossing each of the seven bridges just once, and ending up wherever you started?”A representation of the… Read More

C Algorithms – Gnome Sort

Exforsys
Gnome sort is an extremely simple sorting algorithm, very similar to insertion sort. Also, it is another comparison and exchange sort. You could say that it looks like bubble sort, and you would be right. How it works: In gnome sort, two adjacent elements are compared, and if they are in the wrong order, they are swapped. The comparison continues with the next element, and the same condition is checked, but the order is wrong, a swap takes place, and after the swap, the lower element is now compared to… Read More

C Algorithms – Comb Sort

Exforsys
Comb sort is a simple sorting algorithm which improves on bubble sort. The main idea for this type of algorithm is to eliminate the small values near the end of the list, as these slow down the sorting process. How it works: In comb sort, the main usage is of gaps. For example, in bubble sort the gap between two elements was 1 whilst here the gap starts out as a large value and shrinks until it reaches the value 1, when it practically becomes bubble sort. The shrink factor… Read More

C Algorithms – Bucket Sort

Exforsys
Bucket sort is a sorting algorithm that works by inserting the elements of the sorting array intro buckets, then, each bucket is sorted individually. The idea behind bucket sort is that if we know the range of our elements to be sorted, we can set up buckets for each possible element, and just toss elements into their corresponding buckets. We then empty the buckets in order, and the result is a sorted list. It is similar to radix sort. How it works: Initially we have to set up an array… Read More

C Algorithms – Quick Sort

Exforsys
Quick sort is a comparison sort developed by Tony Hoare. Also, like merge sort, it is a divide and conquer algorithm, and just like merge sort, it uses recursion to sort the lists. It uses a pivot chosen by the programmer, and passes through the sorting list and on a certain condition, it sorts the data set. How it works: A pivot is chosen from the elements of the data set. The list must be reordered in such a way that the elements with the value less than the pivot… Read More

What is Exploratory Testing

Exforsys
Is exploratory testing similar to an ad-hoc test or monkey testing?  Among software testers, there is admittedly, still some confusion with regard to the term "exploratory testing".  The confusions lie in its technicalities; An exploratory test is almost similar to monkey testing or an ad-hoc testing and these 3 testing methods are unscripted in their nature. The term ‘exploratory testing’ was first publicly used by Cem Kaner in the book “Testing Computer Software”. Another known pioneer of exploratory testing is James Bach.  The definition provided by Bach states that, “Any… Read More

C Algorithms – Merge Sort

Exforsys
Merge sort is another comparison based sorting algorithm. Also, it is a divide and conquer algorithm, which means the problem is split into multiple simplest problems and the final solution is represented by putting together all the solutions. How it works: The algorithm divides the unsorted list into two sub-lists of about half the size. Then sort each sub-list recursively by re-applying the merge sort and then merge the two sub-lists into one sorted list. Step by step example : Having the following list, let’s try to use merge sort… Read More

C Algorithms – Counting Sort

Exforsys
Counting sort is a sorting algorithm that is not based on comparison like most other methods. This method of sorting is used when all elements to be sorted fall in a known, finite and reasonably small range. How it works: The algorithm refers to finding for each element a[i] the number of elements from the array that are lower than it. Step by step example : Having the following list, let;s try to use counting sort to arrange the numbers from lowest to greatest: Unsorted list, the array A contains… Read More

C Algorithms – Heap Sort

Exforsys
Heapsort is a comparison based algorithm. It bases on building a heap tree from the data set, and then it removes the greatest element from the tree and adds it to the end of the sorted list. There are two ways to do this, either to add the highest value to the root of the tree, or as one of the left/right child with the greatest depth. How it works: The heap tree is built according to the data set. Then the greatest value is move to the root of… Read More

C Algorithms – Selection Sort

Exforsys
Selection sort, also called naive (selection) sort, is an in-place comparison sort. It may look pretty similar to insertion sort, but it performs worse. It is a quite simple sorting algorithm, and may perform better than more complicated algorithms in particular cases, for example in the ones where the auxiliary memory is limited. How it works: First it finds the smallest number in the array and exchanges it with the element from the first position, then it finds the second smallest number and exchanges it with the element from the… Read More

C Algorithms – Radix Sort

Exforsys
Radix sort is a sorting algorithm that sorts the data, integers for example, by splitting the numbers into individual digits and comparing the individual digits sharing the same significant position. Also, a positional notation is required, because instead of integers there could be strings of characters or floating point numbers. The radix sort can be classified into 2 types: LSD (least significant digit) or MSD (most significant digit). The LSD sorting type begins from the least significant digit to the most significant digit and the MSD works the other way… Read More

C Algorithms – Shell Sort

Exforsys
Shell sort is a generalization of the Insertion Sort, it sorts subsequences that become increasingly higher, until it is reached the value n – the total number of elements. Each subsequence i is determined by a number h_i called increment. Also, the increments must satisfy the following condition: h_t > h_t-1 > h_t-2 > … > h_2 > h_1 Step by step example : Having the following list, let’s try to use shell sort to arrange the numbers from lowest to greatest: Unsorted list: 16, 4, 3, 13, 5, 6,… Read More

C Algorithms – Insertion Sort

Exforsys
Insertion sort is a simple comparison sorting algorithm, that considers at a step k, the elements of the array A[0,k-1] are already sorted out, and the element on the k position will be inserted that way that after the insertion, the elements A[0,k] are sorted out. Inserting the k element in the A[0,k-1] sequence requires a few steps: the element must be retained in a temporal variable; moving all the elements from the A[0,k-1] array that are greater than A[k] with a position to the right (this presumes a run… Read More

C Algorithms – Bubble Sort

Exforsys
Bubble sort is a simple sorting algorithm, which compares repeatedly each pair of adjacent items and swaps them if they are in the incorrect order. At the first run, the highest element of the list ends on the last place of the sorted list, and then, at the following run, the next highest element ends on one position lower than the previous element and so on. The initial list is finally sorted, when at a run, no swaps occur. Even though it’s one of the simplest sorting algorithms, it’s almost… Read More

For example, some of the software which project managers and their teams may use include budget management software, scheduling software, and resource allocation software. These are just a few of the different software types which are used, and they are most often useful when it comes to handling large projects which are very complex. While project management software packages carry out a variety of different tasks,… Read More

Work Breakdown Structure (WBS)

Exforsys
No matter how well the PM plans out their project, in most situations, things will not go exactly as planned. The entire project team must take the time to develop the plan, and this task should not simply be left up to the project manager. What this ensures is that the experience of the entire team should always be considered, and each person must be committed and feel as though they have an ownership in the project. Having said that, one thing that good project teams should always consider developing… Read More

Risk Control Within Project Management

Exforsys
Studies have shown that when project managers take the time to incorporate risk management into their projects, the projects tend to become much more successful. As the name suggests, risk management involves the control of the various risk factors which are related to a project. It requires you to not only monitor the project, but take the time to review potential risks, as well as making crucial decisions which involve dealing with potential dangers to the project. The combination of risk management in conjunction with project management is quite new,… Read More

Once it has been approved, it will be placed within the project master… Read More

Project Plan Structuring Process

Exforsys
It is very important for the project manager to take the time to plan the project, and this includes the initiation as well as the specification phases. It will also be necessary for project managers to work with the stakeholders, not only for the initiation phases for the project, but also for the planning and specifications as well. It will first be necessary to offer a name for the project, a name that will act as a clear overview of it as well as its scope. It may also be… Read More

Project Management Structure and Variables

Exforsys
The Project Management Triangle The most basic structure for project management is called the PM triangle. As with any project that requires a group of humans to reach towards a goal, a project must be completed successfully under specific circumstances. While there are many circumstances or constraints that a project may face, three of the best known as cost, scope, and time. It is these three factors that form the structure of the PM triangle. When the constraints are refined to a much higher degree, performance can also be thought… Read More

Project Management Approach

Exforsys
A project is best described as an endeavor which is finite, one which is carried out so that either a product or service can be created. The reason why a project is described as being finite is because it differs from a process or permanent system, in which the goal is to repeatedly create a product for extended periods of time. The management for both is quite different. What is Project Management? Project management is the field that involves the planning and handling of resources that allows a team to… Read More

Creating Project Cost Estimates

Exforsys
For most projects, the highest costs will be connected to the team members. When you consider this, the wisest manner in which cost estimates should be made will be through the creation of a project schedule (via a program such as Microsoft Project), which has resource management functions that give you the ability to measure the different types and amounts of labor. When cost estimates are made for projects, they are usually accomplished through the sum of estimates for the separate elements which make up the project. The pieces could… Read More

C Programming – Data Types : Part 2

Exforsys
Structure A struct is an aggregate type, meaning that it is made up of other objects. The objects that make up a struct are called its members. The members of a struct may be accessed by the ‘.’ or ‘->’ operators. A struct may be named or unnamed. Let’s look at some examples: #include      struct person    {            char first[100];            char last[100];            int  age;            struct {                    char addrline[500];                   char city[100];                   char state[30];                   char zip[15];           } address;   };  … Read More

Comparison Between SDLC Models

The SDLC Models There are a number of different SDLC models available, and they are designed by experts who specialize in software development. Fresh SDLC models are being introduced all the time, and… Read More

Project Control Systems

Exforsys
To develop a deeper understanding of project management, it is first important to become familiar with project control systems. Project control could be thought of as an element within a project which is responsible for making sure it is on track, as well as on time and within the defined budget. Project control should start early on within the project, and it should only end once the project has gone through the implementation review. The Five Project Management Elements Traditionally, there are five methods which are associated with project management,… Read More

Project Manager

OOAD Classes

Exforsys
Understanding the Ways in which Classes are Connected Inheritance is a very important concept within the object oriented programming paradigm. Inheritance is essentially comprised of the merger of two simple concepts, which are reuse and abstractions. To begin with, you may recognize that two constructs, such as X and Y, have something which relates them together. If you do not wish to deal with this shared aspect more than once, then you have the option of creating a construct called Z that will be responsible for holding the commonality, taking… Read More

OOAD Objects Interactions

Exforsys
How Objects Interact Within the world of OOAD, the interaction of objects will occur within patterns, and these patterns may be broken down into two categories, which are different because of the roles which are associated with the participants. The first of these patterns is the event producer object and one or more objects which are connected to the event consumer. The consumer interaction which is associated with the producer may make use of communication which is one-way. Some examples of this include the items on a menu, a buyer… Read More

OOAD Object Dynamics

Exforsys
Understanding Behavior It is important to consider the importance of behavior when it comes to objects which are dynamic. Describing a behavior can become notoriously difficult with respect to OOAD. Physics will borrow numerous concepts from mathematics, such as differential equations in order to describe entities which change, as well as gases, fluids, or things of this nature. The ways in which the entities behave within the domains are important, but they will often be incapable of offering satisfaction for differential equations. Even something relatively basic such as the piston… Read More

OOAD Objects Relationships

Exforsys
What are Relationships? It is important to take into consideration the static similarities that often exist among the objects. This means that you must also take into consideration the connections which are made with ER modeling. For instance, the Ownership relation is responsible for making a connection with the Client class and the Account class. The relationship may be found within a group of tuples which are typed. They will be typed within the sense that the nth element within the tuple is the instance for the set domain or… Read More

OOAD Object Statics

Exforsys
Instances Objects encompass both tangible as well as non-tangible concepts. Some examples which are considered to be non-tangible include electronic transactions, newspaper articles, or phone calls. There will be times when it is necessary to speak of a specific instance within your system model. For instance, the bank may be comprised of a number of important system accounts. You may wish to describe employees, as well as executive officers. At the same time, the collection of classes will generally be described. The term "class" is used to describe a group… Read More

OOAD Analysis

Exforsys
Analysis in Software Development is Crucial The process of creating an artifact which is complex is prone to some errors. One reason for this is because of the intangibility that comes from the results which are intermediate when developing a software product. Studies have shown that the costs involved with fixing errors have increased costs, and these errors may occur at various stages of the software development life cycle. What this means is that software development teams must place a heavy emphasis on saving money and reducing errors as much… Read More

OOAD Development Phases and Prototypes

Exforsys
Software Development Models Very few software developers can resist the allure of the waterfall model. Software Experts agree that the information gathered downstream can be responsible for altering decisions which were made upstream, and because of this, they violate the basic sequence development algorithms. The conceptualization of a process for development where an individual can backtrack from any point to a previous one has brought about the introduction of the fountain idea, where you assume that the requirements are located near the bottom of the target system. The development process… Read More

OOAD Development Paradigms

Object Oriented Design Building Blocks

Exforsys
Architectural specifications are very useful because they offer software a structure which is very coherent. Coherence can be best achieved through the usage of manifestations which are formal, and the reason for this is because it allows for a representation for the architecture which is verifiable. A number of ADLs, or Architecture Description Languages, have been designed for this purpose, and every one of them are derived from the theory which has already been created. At the same time, there are some techniques which are idiosyncratic when it comes to… Read More

Object Oriented Design
