What are the major capabilities of database management systems (DBMS) and why is a relational DBMS so powerful? Explanin in 100-150 words. Solution A database management system (DBMS) refers to a system software for creating and organizing databases. Capabilities of database management system (DBMS) is explained as below- Data Structuring All information in a digital store is organized into a clear hierarchical structure with records, tables or objects. Every piece of information by help of database can be organized in a kind of catalogue, so that it could be easier to search and update records later on. Query Languages A typical DBMS makes it possible to utilize query languages for collecting, searching, sorting, and modifying. Multi-user Access DBMS provides many users access to all types of information stored in one and the same data store. The relational database is the key method for organizing and maintaining data in information systems as it is so flexible and easy to get to. It organizes data in two-dimensional tables called. Each row expresses a record, and each column represents an attribute or field. Each table also contains a key field to identify each record for manipulation. Relational database tables can be add easily to send data required by users. Hence, relational database is powerful..

Object-oriented programming (OOP) is a computer programming model that organizes software design around data, or objects, rather than functions and logic. An object can be defined as a data field that has unique attributes and behavior. OOP focuses on the objects that developers want to manipulate rather than the logic required to manipulate them. This approach to programming is well-suited for programs that are large, complex and actively updated or maintained. This includes programs for manufacturing and design, as well as mobile applications; for example, OOP can be used for manufacturing system simulation software.

A database management system (DBMS) is a software application that allows users to store, organize, and manage large amounts of data in a structured and efficient manner. DBMS provides a centralized repository for data that can be accessed and manipulated by multiple users and applications simultaneously. The primary functions of a DBMS include data storage, data retrieval, data security, and data integrity. DBMS allows users to define, create, and manipulate data using a variety of tools and interfaces, such as SQL queries, forms, and reports. DBMS typically include features such as transaction management, concurrency control, backup and recovery, and query optimization to ensure the efficient and reliable operation of the system. DBMS can be categorized into different types based on their architecture, such as relational, object-oriented, and NoSQL. Each type of DBMS has its own strengths and weaknesses, and the choice of DBMS depends on the specific requirements of the application. Overall, a DBMS plays a critical role in managing large and complex data sets, and it is an essential tool for organizations that need to store, access, and analyze large volumes of data efficiently and effectively.

Part C Assessments As you examined each specific connective tissue, you should have noted some general characteristics that they possess as described in the laboratory exercise. List any of these you were able to observe. describe them from the photos in your manual and textbook. How does the Matrix of these tissues differ? Solution Different kinds of connective tissues: Connective tissue represents the binding tissue which helps in holding and keeping the tissues/cells at their right places. The connective tissue can be of atleast three types: 1. Blood/fluid connective tissue 2. Bones/cartilage or the solid connective tissue 3. Organ specific soft connective tissue such as in myocardium, epididymis etc. The basic features of the connective tissues shared by all types are discussed below: 1. MATRIX: A matrix or medium is always present in the connective tissue. This matrix represents the ground matter in which all the cell types/tissue types are actually embedded. The matrix can be solid or liquid in nature depending upon the nature of host tissue. 2. GROUND MATTER: The ground matter is a characteristic of each type of tissue. It is mainly composed or organic and inorganic matter and helps in providing shape and support to the organ/tissue. This matrix is resistant to many infections and also provides immune support to the host tissue/organ. 3. CELLS: Most of the times, the matrix is also accompanied by particular types of immune- responsive cells which help in preventing infections in the host tissue/organ. Depending upon the nature of host tissue/organ, the types and number of these cells can vary. How does the Matrix of these tissues differ? The matrix is a highly flexible part of the connective tissue. Depending upon the nature of host tissue, the matrix can be solid or liquid in nature. For example, the matrix of blood is plasma which is a liquid in nature. However, it also contains all the characteristics of a basic matrix i.e. possession of different types of cells and helps in preventing infections. Similarly, the matrix of bones is solid in nature which comprises of not only ground matter (both organic and inorganic), but also contains different types of cells which help in maintaining structure and function of bones. Thus, different types of tissues/organs carry different types of matrices which help in maintenance of their functionality..

I need help summarizing a research article!! I need to summarize an academic article in 500 words or less and the paper is confusing me. The paper is on Ctneophora and how they are related to other animals. Can anyone help me Interrupt this article? I linked the article. file:///C:/Users/malge/Downloads/PNAS-2015-Whelan-5773-8-1%20(1).pdf Solution Definition of Ctenophora: Soft, transparent, dioplblastic, marine metazoans with out nematocysts, but with adhersive colloblasts and eight meridional ciliated combplates called Ctenophora. Features of Ctenophora: Ctenephores from an animal phylum that is more complex than sponges, about as complex as cnidarians (jellyfish, sea anemones etc.,) and less complex than bilaterians ( which includes almost all other animals). Unlike sponges, both ctenophores and cnidarians have : cells bound by inter- cell connection and carpet- like basement membranes; muscles; nervous systems; and some have sensory organs. Ctenophores are distinguished from all other animals by having colloblasts, which are sticky and adhere to prey, although a few ctenophore species lack them.Like sponges and cnidarians, ctenophores have two main layers of cell that sandwich a middle layer of jelly- like material, which is called the mesoglea in cnidarians are ctenophoress; more complex animals have three main cell layers and no intermediate jelly- like layer. Hence ctenophores have traditionally been labelled diaploblastic, along with sponges. Ctenophores have a type of muscles that , in more complex animals, have three main cell arises from the middle cell layer, and as a result text books classify ctenophores as triploblastic, while other still regard them as diploblastic. Ranging from about 1 millimeter (0.039in) to 1.5 meters (4.9) in size, ctenophores are the largest non- colonial animals that use cilia as their main method of locomotion. Most species have eight strips, called comb rows, that run the length of their bodies and bear comb- like bands of cilia, called ctenes, stacked aiong the comb rows so that when the cilia beat, thosee of each comb touch below. The name ctenophores means comb- bearing from the Greek meaning comb and the suffix meaning carrying. Types of Ctenophores Oceanic ctenophores: In addition to the relative well- known coastal ctenophores, there are many species found only far offshore near the surface, or in the mid- water or in the deep sea. Although the ocean seems rather uniform, each species is representative of only a small portion of the water column, defined by a combination of water temperature, light availability, depth and other factores- many oceanic cternophores species are found under similar conditions world wide. Oceanic ctenophores tend to be much more fragile that coastal species, because they do not need to tolerate wave action or the turbulence and sediment load of coastal water. Some of them have fastastic, unlikely shapes. Recognizable species include the lobe- flapping Ocyropsis, which.

Explain why Drosophila are often used as model organisms in the study of genetics: Solution Drosophila melanogaster or fruit flies have about 75 of the genes that causes disease in humans so scientists are able to know about the human genetics clearly by studying the fruit fly genetics. Fruit flies are less expensive when compared with rat and other organisms, they are small and it is very easy to take care of it and easy to carry out the research. Fruit fly has many characteristics to study about animal behaviour and development,neurobiology, human genetic diseases and their conditions. Drosophila has become an predominant model and it gives information about how the genes direct the development of embryo from a single cell to mature multicellular cells. Drosophila has many set of molecular tools and mutants that dissect the genetic pathway that are important for the normal and abnormal conditions of cardiac functions. It became popular to investigate the genes that causes cardiovascular disease. It is easy to evolve many generations of fruit fly because of its short lifespan due to this many experiments can be easily carried out. By the above conditions,we can consider that the Drosophila melanogaster is often used as a model organism in the study of genetics..

Assess the types of stakeholders involved in the development process for the product/service Evaluate the impact of key inputs from stakeholder groups on new product/service development efforts. Analyze the role these key stakeholder groups can play in contributing to the success of a new product/service Justify at least two persuasive strategies that can be used to engage stakeholders in new product/service development projects. Assess the key competitive advantages that utilizing the current trends in information technology (IT) will deliver to the area of new product/service development. Solution Stakeholders include Shareholders ,Banks,financial institutions and Private Equity in the Development Process for a tire company like Michelin tires Each of Michelin businesses is encouraged to identify and engage with key stakeholders at a national and operational level. Michelin Stakeholder Relations Guidance provides information to help these businesses identify and engage with their stakeholders. A stakeholder is an individual who is affected by or who can affect a project\'s outcome. Stakeholders shape projects in the early stages, ensuring resources are available to contribute to project success, and provide insight regarding the probable reaction to a project\'s outcome, which facilitates project adjustments when necessary to win organizational support. The roles of stakeholders change throughout a project life cycle. However, the willingness of stakeholders to perform the activities assigned to them during the project planning process greatly contributes to the success or failure of the project. Group stakeholder engagement on sustainability is managed by the Performance and Responsibility team at Michelin Group. Site-level stakeholder engagement is the responsibility of site managers. Together, these provide critical input to help guide Michelin strategy and PRM activities..

Why should assembly language be avoided for general application development? Under what circumstances is assembly language preferred or required? Solution Reasons for avoiding Assembly Language for General Application Development: (i) It is difficult to understand the code (as Assembly Language is a low-level language). Debugging and modification of code requires extensive work. (ii) Application Development time will be higher than higher level languages because even the basic operations like additions, subtractions etc needs to be implemented as part of the code. (iii) In case of higher level languages, we can use the existing libraries to complete the development work faster. This is not possible with the Assembly Language. (iv) Assembly Languages are hardware specific and not portable to all machines. This is not the case with the higher level languages. Circumstances under which Assembly Language is preferred: (i) Assembly Language is preferred when we have a limited availability of memory and computational space. To maximum utilize the available memory and computational space, Assembly Language is preferred over Higher Level languages in such cases. Ex: chipsets (ii) Assembly Language is also used when we need to do some hardware manipulation. This is not possible with higher level languages. (iii) When we need to design something specific to a computer architecture where support for higher languages is not available yet..

Who was Jesus of Nazareth? What was his message? How did he convey that message? What role did parables and miracles play in his ministry? What event convinced his followers that he was more than an ordinary man? Solution Jesus Christ, best known as Jesus of Nazareth or simply Jesus, is Christianity\'s central figure, both as Messiah and, on most Christians, as God incarnate. Muslims regard him as a general major prophet several regard him because Messiah. Many Hindus also recognize him as a general manifestation belonging to the divine, and some Buddhists identify him as a Bodhisattva. Jesus was born sometime right before 4 B.C. He was raised in Nazareth, a tiny village in Galilee, within the peasant class. Jesus\'father has been a carpenter and the man became one, too, meaning that they had likely lost their agricultural land at some point. Jesus was raised Jewish and the man remained deeply Jewish nearly every one of his life. His intention wasn\'t to create a new religion. Rather, he saw himself as doing something within Judaism. His followers experienced him after his death. It is see-through that they had visions of Jesus as that you had known him during his historical life. Only after his death did they declare Jesus to be \"Lord\" or \"the Son of God.\" Right away of Jesus\'life through His death and beyond, the Herodian dynasty ruled Palestine and nearby area, the lands belonging to the eastern Mediterranean coast. These rulers were clients of Imperial Rome, who served with all the appointment and permission of Rome. The firstly this family turn out to be appointed as ruler in Israel was Herod the Great. Upon his death, his kingdom was divided between three of his sons: Herod Archelaus, Herod Antipas, and Philip the Tetrarch. The Parables of Jesus can be found in all the canonical gospels, whereas in the a few of the non-canonical gospels, but are found mainly while in the three synoptic gospels.They represent a vital element of the teachings of Jesus, forming approximately 33 % of his recorded teachings. Christians place high focus on these parables; because they are the purported words of Jesus, they can indeed be believed to be what the Father has taught, indicated by John 8:28 and 14:10. Jesus parables are seemingly simple and easy and memorable stories, often with imagery, and all sorts of convey messages. Scholars have commented that although these parables seem simple, the messages they convey are deep, and central in the teachings of Jesus. Christian authors view them not as mere similitudes which serve the purpose of illustration, but as internal analogies in which nature becomes a witness for the spiritual world.
