Agile Software Development, 6 Advantages
Agile development is a strategy of software development in which the process occurs though short increments. The phases of the development process occur continuously in iterative cycles, involving a requirements phase, design and implementation, testing, and reporting. Stakeholders and designers meet after each increment to discuss what has occurred, re-evaluate requirements and determine priorities. This allows for greater transparency between clients and programmers and clients have greater influence in what is being designed to ensure the product is what they want. The traditional waterfall method general involves the stakeholders at the beginning requirements phase, and then the development company…
What is a relational database?
It is a database that stores the information about both data, for example for a person detail that is link with their car details that they have bought it from the company. The data and relationships are showed in an entity which is in a flat, two dimensional tables. We would use a relational database in a company such as a car company so when they want to store their customers information and what car did they buy, they use a relational database which stores the…
In this modern day, databases are based heavily on relational models in which tables are the fundamental building blocks. We may ask the question as to where ER comes in database design, its importance and the need for ER modelling in modern databases. In an attempt to answer these questions, we get to understand that ER is a high-level description of the proposed database, useful for understanding the requirements gathered from a client, in our case The Reproduction Antiques Company. It…
According to (Connolly, 2003) the database is “A shared collection of logically related data, and a description of this data, designed to meet the information needs of an organization”. The Database Management System (DBMS) is software that enables users to define, create, maintain and control access to the database. The database has identified three levels of abstraction. All these three levels will have different aspects and they are as follows:
• Physical or external level- The database…

their customers better. This business strategy is important as it provides the data they need to make predictions for the future and it gives them the ability to modify when results are affected. In order to take this strategy into consideration, firms must provide their insights about customers, adapt to business practices and engage with customers. If firms don’t use predictive information to change the future, then they are just wasting their time (Gualtieri & Curran, 2015, p. 2). There are…

Enrollment Projections, Predictive Modeling, and Territories
Creating a method to track enrollment can provide enrollment managers a snapshot of projections for upcoming enrollment, and allow for more precise budgeting using the predictive model. Enrollment predictors can be created and tracked using simple software such as…
The theory of Continuous Auditing was established by Vasarhelyi and Halper (1991). Continuous auditing entails the real-time monitoring and analysis of the entire population of records. The premise of this methodology is based on the concept of “audit by exception” where deviations (e.g. control variances) are flagged as alerts and forwarded to the responsible parties (e.g. management, internal auditors, business owners) for investigation. Continuous auditing has evolved from an academic theory…
Definition of Data: The term data is known as representation of objects, events which are stored and recorded in the computer and the data exists in a variety of forms such as values, variables and numbers and so on etc.
EX: The database in a hospital contains data such as name of the patient, address, disease and contact number.
Definition of Database:
The term database is determined as data collection in an organized manner and every data present is related to each other in some other way.…
Spiral methodology situations where most appropriate and situations
1. When the project is large.
2. Where the software need to risk evolution.
3. Software need to require to significant changes.
4. If client have enough time is frame and to get end user feedback.
5. Research and exploration are expected.
6. Users are unsure of their needs.
Spiral methodology situations where least appropriate and situations
1. If you have big projects.
2. If your project is very complex.
