Technical Area Overview
Software Development
Software development is the process programmers use to build computer programs. The process, also known as the Software Development Life Cycle (SDLC), includes several phases that provide a method for building products that meet technical specifications and user requirements.
Software Integration
In this case, the integrating process is, basically, creating interconnections between all subsystems (each subsystem is connected to every other one). The diagram of a complete system with connections looks like a star or a plate of spaghetti (it depends on the number of connections).
Information Security
Information security (InfoSec) enables organizations to protect digital and analog information. InfoSec provides coverage for cryptography, mobile computing, social media, as well as infrastructure and networks containing private, financial, and corporate information.
Software Maintenance
Software maintenance – It stands for all the modifications and updations done after the delivery of software product. There are number of reasons, why modifications are required.
Software Development project management
The process of developing a software product using software engineering principles and methods is referred to as software evolution. This includes the initial development of software and its maintenance and updates, till desired software product is developed, which satisfies the expected requirements.
Structured Design
In function-oriented design, the system is comprised of many smaller sub-systems known as functions. These functions are capable of performing significant task in the system. The system is considered as top view of all functions. Function oriented design inherits some properties of structured design where divide and conquer methodology is used. This design mechanism divides the whole system into smaller functions, which provides means of abstraction by concealing the information and their operation.. These functional modules can share information among themselves by means of information passing and using information available globally.
Another characteristic of functions is that when a program calls a function, the function changes the state of the program, which sometimes is not acceptable by other modules. Function oriented design works well where the system state does not matter and program/functions work on input rather than on a state.
Software Design Approaches
Top Down Design
Top-down design takes the whole software system as one entity and then decomposes it to achieve more than one sub-system or component based on some characteristics. Each sub-system or component is then treated as a system and decomposed further. This process keeps on running until the lowest level of system in the top-down hierarchy is achieved. Top-down design is more suitable when the software solution needs to be designed from scratch and specific details are unknown.
Bottom-up Design
The bottom up design model starts with most specific and basic components. It proceeds with composing higher level of components by using basic or lower level components. It keeps creating higher level components until the desired system is not evolved as one single component. With each higher level, the amount of abstraction is increased. Bottom-up strategy is more suitable when a system needs to be created from some existing system, where the basic primitives can be used in the newer system.
Both, top-down and bottom-up approaches are not practical individually. Instead, a good combination of both is used.
Information systems security management
Information security (InfoSec) enables organizations to protect digital and analog information. InfoSec provides coverage for cryptography, mobile computing, social media, as well as infrastructure and networks containing private, financial, and corporate information. Cybersecurity, on the other hand, protects both raw and meaningful data, but only from internet-based threats. Organizations implement information security for a wide range of reasons. The main objectives of InfoSec are typically related to ensuring confidentiality, integrity, and availability of company information. Since InfoSec covers many areas, it often involves theimplementation of various types of security, including application security, infrastructure security, cryptography, incident response, vulnerability management, and disaster recovery.

Information Security Goals in an Organization. There are three main objectives protected by information security, collectively known as CIA:
Confidentiality—prevents unauthorized users from accessing information to protect the privacy of information content. Confidentiality is maintained through access restrictions. Breaches of confidentiality can occur due to human error, intentional sharing, or malicious entry.
Integrity—ensures the authenticity and accuracy of information. Integrity is maintained by restricting permissions for editing or the ability to modify information. Loss of integrity can occur when analog information is not protected from environmental conditions, digital information is not transferred properly, or when users make unapproved changes.
Availability—ensures that authorized users can reliably access information. Availability is maintained through continuity of access procedures, backup or duplication of information, and maintenance of hardware and network connections. Loss of availability can occur when networks are attacked due to natural disasters, or when client devices fail.
Integration of software applications
Integration in software engineering means combining software parts (so-called subsystems) into one system. Integrated systems.demonstrate better performance comparing to the sum of all independent ones. What is more important, a holistic application delivers greater functional significance. It’s more convenient to distribute and use. Integrating is trending as never before these days. More and more mergeable systems appear on the Internet. Therefore, connecting with them is vital.
Software Implementation Challenges
There are some challenges faced by the development team while implementing the software. Some of them are mentioned below:
Code-reuse – Programming interfaces of present-day languages are very sophisticated and are equipped huge library functions. Still, to bring the cost down of end product, the organization management prefers to re-use the code, which was created earlier for some other software. There are huge issues faced by programmers for compatibility checks and deciding how much code to re-use.
Version Management – Every time a new software is issued to the customer, developers have to maintain version and configuration related documentation. This documentation needs to be highly accurate and available on time.
Target-Host – The software program, which is being developed in the organization, needs to be designed for host machines at the customers end. But at times, it is impossible to design a software that works on the target machines.
Software integration few methods
Horizontal integration (also known as Enterprise Service Bus). This method is based on creating a subsystem for communication purposes. Why is it effective Implementing Enterprise Service Bus View reduces the number of connections per each subsystem to one. Every part of the system communicates with other parts through the ESB which translates one interface into another. This is an extremely flexible approach. It’s possible to add, replace or modify any part of the system without affecting the others. You just need to implement the appropriate interface between a new subsystem and the ESB. Horizontal integration isn’t a cost-effective method for small systems. Nevertheless, take into account that the number of subsystems tends to grow as time passes. It gets cheaper and cheaper to expand the system compared to other integration approaches. So, it is safe to say that it is highly efficient in the long run. The idea is to create a common format insignificantly different from the application-specific one. The EAI system converts between these two across an enterprise with the help of the data transformation service.
Software integration process
Just like with any complicated process, a proper software integration has six stages;
Gathering Definitions, Specifications, and Requirements;
Analysis;
Architecture Design and Management Plan;
System Integration Design; Implementation;
Evaluation and Maintenance;
Gather the detailed requirements.
The first step of integration is to discover and list out all core and subtle specifications of systems you are going to integrate. There is no one-fits-all solution for every case. Every single company is different in its approaches.
Software Maintenance
Software maintenance It stands for all the modifications and updations done after the delivery of software product. There are number of reasons, why modifications are required, some of them are briefly mentioned below:
Market Conditions – Policies, which changes over the time, such as taxation and newly introduced constraints like, how to maintain bookkeeping, may trigger need for modification.
Client Requirements – Over the time, customer may ask for new features or functions in the software.
Host Modifications – If any of the hardware and/or platform (such as operating system) of the target host changes, software changes are needed to keep adaptability.
Organization Changes – If there is any business level change at client end, such as reduction of organization strength, acquiring another company, organization venturing into new business, need to modify in the original software may arise.
Types of software maintenance
In a software lifetime, type of maintenance may vary based on its nature. It may be just a routine maintenance tasks as some bug discovered by some user or it may be a large event in itself based on maintenance size or nature. Following are some types of maintenance based on their characteristics:
Corrective Maintenance — This includes modifications and updations done in order to correct or fix problems, which are either discovered by user or concluded by user error reports.
Adaptive Maintenance — This includes modifications and updations applied to keep the software product up-to date and tuned to the ever changing world of technology and business environment.
Perfective Maintenance — This includes modifications and updates done in order to keep the software usable over long period of time. It includes new features, new user requirements for refining the software and improve its reliability and performance.
Cost of Maintenance
Reports suggest that the cost of maintenance is high. A study on estimating software maintenance found that the cost of maintenance is as high as 67% of the cost of entire software process cycle. On an average, the cost of software maintenance is more than 50% of all SDLC phases. There are various factors, which trigger maintenance cost go high, such as:
Real-world factors affecting Maintenance Cost:
The standard age of any software is considered up to 10 to 15 years.
Older softwares, which were meant to work on slow machines with less memory and storage capacity cannot keep themselves challenging against newly coming enhanced softwares on modern hardware. As technology advances, it becomes costly to maintain old software.
Most maintenance engineers are newbie and use trial and error method to rectify problem.
Often, changes made can easily hurt the original structure of the software, making it hard for any subsequent changes.
Changes are often left undocumented which may cause more conflicts in future.
Software-end factors affecting Maintenance Cost:
Structure of Software Program
Programming Language
Dependence on external environment
Staff reliability and availability
Activities go hand-in-hand
Identification & Tracing — It involves activities pertaining to identification of requirement of modification or maintenance. It is generated by user or system may itself report via logs or error messages.Here, the maintenance type is classified also.
Analysis — The modification is analyzed for its impact on the system including safety and security implications. If probable impact is severe, alternative solution is looked for. A set of required modifications is then materialized into requirement specifications. The cost of modification/maintenance is analyzed and estimation is concluded.
Design — New modules, which need to be replaced or modified, are designed against requirement specifications set in the previous stage. Test cases are created for validation and verification.
Implementation — The new modules are coded with the help of structured design created in the design step.Every programmer is expected to do unit testing in parallel.
System Testing — Integration testing is done among newly created modules. Integration testing is also carried out between new modules and the system. Finally the system is tested as a whole, following regressive testing procedures.
Acceptance Testing — After testing the system internally, it is tested for acceptance with the help of users. If at this state, user complaints some issues they are addressed or noted to address in next iteration.
Delivery — After acceptance test, the system is deployed all over the organization either by small update package or fresh installation of the system. The final testing takes place at client end after the software is delivered. Training facility is provided if required, in addition to the hard copy of user manual.
Maintenance management — Configuration management is an essential part of system maintenance. It is aided with version control tools to control versions, semi-version or patch management.
