By John Pereless- Custom Software Development and Basics of Customization

Custom Software Development is a professional terminology for information technology industries or personal specializing in implementing on demand software for accomplishment of specific set of tasks for customers and applications. The final deliverable product is not usually a all purpose i.e. of general use in the conventional sense of being marketed and sold to a general group of people or say targeted audience. Rather, it is developed and delivered on an order basis to a specific buyer or organization etc and often cannot be sold or else provided to other users as it is a copyright for the user who requested originally also it needs to be further customization to fulfill the next buyers needs etc with a fresh set of requirement.

Custom software pr tailored application is supposed to offer specialized and/or special user interfaces/intermedia connections, workflow, and system that provide the end user with further advantages and outcome value than off-the-shelf (built in for all) applications offer.

Custom software development providers offer assistant  on current scenario for fast changing enterprise/business solution providers on their business requirements to keep harmony with the rapidly changing market business niche environment with the help of advanced upgraded system approach and error free functional management. Most custom software providers can implement technical documentation for software, help with implementation of software to development, etc.

Why we need Custom Made Applications or Software:

We are living in the computer age where we need everything done on a fraction of second and for that we do effort to keep people happy with our business. As a customer & end user, we look forward for better & fast services. And it is possible through high technology outcomes. In order to deliver that, we need some applications which can manage and handle our extra labor. Here comes custom software or application development services in focus.

Types of Custom Software Applications:

(1) Word Processing Application Software

If you have a publishing place or a workshop where you need to manage so many files or documents, WP application is dedicated to you.

(2) Database Management Software

Executing DB operations effectively & efficiently is vital for any business tier and the most essential task to keep track on record. Database Software helps in maintaining the log for the financial as well as informational data. DB software is integrated and linked with the current front as well as back-end of the system or custom applications.  

(3) Multimedia Software

No doubt, you need multimedia on your system for playing games, audio or video playback etc thus they are known to be multi-media software.

(4) Presentation Software

As the name itself indicates that being in a business, it requires a lot of information and details to be communicated with outer world and at the same time it’s presented to clients, stakeholders and partners etc.This sort of task is done by presentation software and there are so many built in tools available to get this done professionally. Prototypes, Wireframes, Virtual model, layouts etc are being discussed in a company’s presentation.

(5) Spreadsheet Software

When records are greater in numbers then you need spreadsheet software to perform calculations and maintain the same in a tabular form. Excel and Lotus 1 2 3 are the best known spreadsheet applications that would help in achieving desired goal for you.

(6) Simulation Software

As the name itself pointing that these are the customized software developed to achieve some sort of research & development purpose and for observing the outcomes.

(7) Educational Software

Educational Software is focused on teaching and self-learning. A few existing Edu niche like Matlab, Encarta, Google Earth and NASA World Wind are some of the top names in this category. Some educational institutions uses it for executing some departmental exercises too.

(8) Enterprise Resource Management Software

This is the most wide and important form of custom application development because there are so many companies are working for the in-house as well as for global clients in delivering these applications. If you want to manage an organizational Data Flow, an Enterprise Software is a must for you. It doesn’t matter you come from a large business or a small business, its a basic need for all of them, dependency on the entities and the level of control you want to command over such operations. ERP (Enterprise Resource Planning) CRM (Customer Relationship Management) and FMS (Financial Management System) are important Enterprise Software these days.

Mobile Application Development And Things To Be Taken Care By John Pereless

By John Pereless:

Let us first find the reason why it is required to build mobile apps and what are these? Basically this world is changing rapidly and we’ve seen a high end demand on portability of the devices. When we talk about application development, the first thought appears with its usability or purpose behind the development and hence this comes with a solution for addressing some problems. We are well familiar with software era and various sort of software development fundamentals. We are now living in the age of mobile or can say smart phones where a person wants everything accessible with his presence.

The modern age of mobile apps is delivering what a person looks after for. Mobile apps are application software, built to deliver some solutions on handheld devices, like personal digital assistants [PDAs], enterprise [commercial] digital assistants or mobile phones..

This world is going mobile & is roaming around the real space i.e. virtual air space, it would be hard to discuss otherwise with more than three hundred millions smartphones, tablets etc already been sold worldwide. This mobile revolution & evolution introduces noticeable changes to the form factor of software solutions that tailored carefully vetting before to initiating the development of a mobile solution.

In a nutshell and as a whole, mobile users normally pay more focus to the user experience, satisfaction and innovation, Also when they have a choice they like a native i.e. local look and feel be it & fit for their email, social networking, checking weather, sport events etc even Google is working and building native apps thoroughly. Moreover, developers can produce a native experience in the browser & thanks to the progress made by various built in SDKs.

If these technological modifications can already make an impact, a mobile solution delivery process, the most versed architectural change introduced by mobility and portability is the evolution from concerned & connected apps to focused applications where VoIP, texting, chatting, location services, data enhancement and services and media may all deliver to offer an experience simply unavailable to a desktop or a Web based application. In early of 2000s, in the rise of SOA, SOAP, many companies had developed the concept of distributed & composite applications [grouped by features] or Connected Systems. Mobile apps advanced and have added this concept additionally to reach it at the next level and enable an ordinary app to consume a mixed of n number of voice, messaging i.e. texting,data add on, geography i.e. location and video services maintained by various 3rd parties which each may have a direct connection with the end user, & totally independent of the application. Focused Apps created solid privacy restrictions (as the app is accessed in granting access to do some actions on contacts, location recognition, movies and clipping, TV programs, commercials etc ). OAuth 2.0 standards have indulged to support these segments. It requires the developer to maintain individual Application programming interfaces keys and (user) access tokens for each type of services. John Pereless: Also developers can no longer depend on a single login option & thats why access modes such as OpenID or LiveID are delivered to this world as they share the identity of the subscriber or commenter with the application and do not provide any authorization capability which is high time demand.

Software Development, Approach & Methodologies By John Pereless

As we all know the basics of software i.e. a well written code or set of instructions that performs specific task as intended in chunks of programs coded in certain language so called programming language. We are lifted above from the beginning era of programming world. We’ve seen such zig-zag and on track scenario on system development life cycle. We achieved a lot from the the modern software age.  

Software development is associated with the computer programming, documenting the piece of code, and testing involved in creating and maintaining applications and frameworks i.e. platforms involved in a software release life cycle and resulting in a software product. The term refers to a process of writing and maintaining the source code, but in a broader sense of the term it includes all that is involved between the conception of the desired software through to the final manifestation of the software, ideally in a planned and structured process. Therefore, software development may include some R & D to get new results as an outcome, new development, prototyping, modification, reuse, re-engineering, maintenance, or any other activities that result in software products.

There are so many reasons why we need to develop software and the most common is to simplifying things and to save human labor hence in a result increase in productivity. We can understand its importance via major organizations working for the welfare of the society & research and development.   

Software can be developed for a variety of goals, the three most common being to meet specific needs of a specific client or business, to meet a perceived need of some set of potential buyers or users, or for fulfilling the personal need. Embedded software development, that is, the development of embedded software such as used for controlling consumer products, such as inbuilt firmware added on your devices such as washing machines, printers internal controlling system, your digital watch etc requires the development process to be integrated or assembled with the development of the controlled physical product.

The need for better quality control of the software development process i.e. software development life cycle has given rise to the discipline of software engineering & reverse engineering at the same time, which aims to apply the methodological systematic approach exemplified in the engineering paradigm to the process of software development. Software testing plays a major role in releasing the software versions. We can have this done in multiple phases for various outcomes. But the ultimate goal of software testing is to deliver a better version and fully user friendly product that meets common goal of achieving the results as well as zero bug identification in terms of operating as well as security of the end user & to the front as well as back-end of the system.

Steps and phases on software development process:

There are multiple approaches to software development: some take a more structured, organized engineering-based approach to developing business solutions & customization is involved a lot in that, whereas others may take a more incremental approach, where software evolves as it is developed piece-by-piece & step by step. Most SDLC methodologies share some combination of the following stages of software development:

(A) Analyzing the problem

This phase is associated with identifying the problem and understanding the actual business or product goal. Analysis of involved users, structure or prototype of product for the business.

(B) Market research

This phase involves market study for the product to be developed. Product scope, competitive market etc are analyzed and created a market research report for further budget and marketing mix analysis.

(C) Gathering requirements for the proposed business solution

In this phase, software developer team ask for more information on business i.e. what will be the business plan? How the business will function? What will be the business logic [Revenue model etc] How the users will interact to the system? etc Once all information is received, development team starts for the next phase which is based on gathered information.

(D) Devising a plan or design for the software-based solution

In this phase, the design prototype is sent to the business owner or main business team for approval. If things are modified, design team accept the changes and work for further etc.

(E) Implementation (coding) of the software

This is very important phase as it involves the software development programming methodology. System is divided into various modules and programming is done for the individual module by the programming team. Integration starts when module wise coding is done.

(F) Testing the software

As we discussed above, in testing all bugs are removed and the developed system is tested on various parameters like speed, security, functioning, operating etc

(G) Deployment

When the system is fully tested, approved by the development as well as the business client end, it is deployed for making it available for the end users.

(H) Maintenance and bug fixing

This is the last phase on all SDLC and software development model. Maintenance and bug fixing is on going processes. The main goal of this phase is to offer support services for technological and structured changes.
