In modern software development, one of the key tasks is to choose the appropriate architecture for the system in the early stages of its design. This article examines two popular software architecture approaches: service-oriented architecture (SOA) and microservice architecture (MSA). Based on the analysis of architectural features, advantages and disadvantages of these approaches, the criteria that influence the choice of an architectural model depending on the specifics of the system are investigated. Microservice architecture, due to its independence and the possibility of rapid scaling, is better suited for dynamic systems with high requirements for flexibility. Service-oriented architecture, on the contrary, is focused on centralized management of services through ESB (Enterprise Service Bus) and provides better opportunities for integration and reuse of components in large corporate systems that do not require frequent changes in functionality. The main focus of the article is the development of an evaluation method that will allow software developers and system engineers to determine at the early design stages which of the architectures, SOA or MSA, is more appropriate to use for a specific system. Taking into account various technical and requirements, the method identifies key criteria that should be paid attention to when choosing an application software architecture.

It is well known that, at the present, a huge amount of information, often referred as Big Data, is processed by each domain of modern society. Big data are well defined by the seven dimensions: Volume, Velocity, Variety, Variability, Veracity, Visualization and Value. The traditional database management systems cannot handle the requirements of high availability, scalability and reliability emerged with Big Data. The good news is that we are now in the age of NoSQL databases. NoSQL do not have a fixed structure, they have a flexible structure and are suited for storing unstructured data produced in a large scale in various field. This work outlines the four main types of NoSQL databases and presents some of their representative solutions.

Applications of science and technology have made a human life much easier. Vision plays a very important role in one’s life. Disease, accidents or due some other reasons people may loose their vision. Navigation becomes a major problem for the people with complete blindness or partial blindness. This paper aims to provide navigation guidance for visually impaired. Here we have designed a model which provides the instruction for the visionless people to navigate freely. NoIR camera is used to capture the picture around the person and identifies the objects. Using earphones voice output is provided defining the objects. This model includes Raspberry Pi 3 processor which collects the objects in surroundings and converts them into voice message, NoIR camera is used detect the object, power bank provides the power and earphones are used here the output message. TensorFlow API an open source software library used for object detection and classification. Using TensorFlow API multiple objects are obtained in a single frame. eSpeak a Text to Speech synthesizer (TTS) software is used to convert text (detected objects) to speech format. Hence using NoIR camera video which is captured is converted into voice output which provides the guidance for detecting objects. Using COCO model 90 commonly used objects are identified like person, table, book etc.
