Caution No blank lines is allowed in the MongoDB Script Sampler. If there is a blank line after MongoDB statement, the statement will still be executed but the word “ok” will be displayed in the response. Add new document into the collection Step 1 Change the “Script” area of the MongoDB Script sampler with insert query. In this case, the query of adding document into the collection is shown as follows: db.getCollection('zips').insert({"city" : "BABYLON", "loc" : [ 32.211100, 44.251500 ],…

Waterfall Methodology Waterfall model was developed as a solution to Ad-hoc development methodologies. • A staged development model • Stages will be completed one after the other. • Subsequent stage can be started once the previous one is completed only. • Waterfall model follow software development process in a linear sequential. • This model phases are do not overlap. Principle of Waterfall Methodology The waterfall model describes 6 phases. I. Requirement gathering. All the…

Data integrity ensures that data is ultimately accurate. This is important when trying to analyze data that is stored in the database or data warehouse. Inaccurate data will lead to false results in reporting and analytics that will affect any business decisions that need to be made. When dealing with data integrity, having the full or complete set of data is a necessity. If only half or some of the data is entered than it cannot be considered accurate. There are several ways to ensure that data…

CRUD – Defining Information Ownership When developing and implementing a relational database, defining the information and users of the system enable definition of the business rules defining the components of the database management system. An example can be evaluated through the use of a CRUD – create, retrieve, update and delete – matrix as it relates to student information and the individuals or departments related to the school that may require access. The resulting model will be used to…

Task 10 (D1) Discuss how potential errors in the design and construction of a database can be avoided. One of the potential errors that can occur when creating a database is that field names and names can be spelt incorrectly due to human error this can be difficult to spot if the database is big the way of making sure that there are no naming errors is to make sure that every is checked regularly and more than twice to make sure that the chances of finding a spelling mistake is reduced. Using…

A. Two Areas of Futuring Anticipating the future is an important component for many disciplines. It is also vital for individuals, businesses, and governments to ensure sustainability going into the future. Essentially, futuring does not concentrate on predicting the future but focuses on developing ways to improve it when it comes. Employing futuring techniques looks at ways to prepare for the future by making the appropriate adjustments based on the future expectations or trends (Sikkema,…

Learning Journal Unit 6 – Introduction to Biology University of the People Author: Murray Ball - Thursday, December, 22nd, 2016 Featured Characteristics of the Common Snapping Turtles Phylum In your assigned readings, you were introduced to the major animal phyla. Choose an animal which represents a particular phylum. Briefly describe its features characteristic of its phylum including morphology, embryology, and physiology. Identify adaptations of your animal compared with other animals. If…

Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object” (3D Print). The process starts by creating a virtual design of the object. The virtual design is made using a 3D modeling program in a CAD (Computer Aided Design) file. Another way the process can start is by using a 3D scanner which makes a 3D digital copy of an object. 3D printing is being used to make individual objects, tailoring to a need rather than replacing…

The rule for first normal form (1NF) is a table in which the intersection of every column and record contains only one value. In other words a table that contains more than one atomic value in the intersection of one or more column for one or more records is not in 1NF. The non 1NF table can be converted to 1NF by restructuring original table by removing the column with the multi-values along with a copy of the primary key to create a new table. See Figure 8.4 for an example of this approach.…

Hierarchal Database “In the network model, the data are represented by collections of records and relationships between data are represented by links. This structure holds for the hierarchical model as well. The only difference is that, in the hierarchical model, records are organized as collections of trees, rather than as arbitrary graphs.”(http://codex.cs.yale.edu/avi/db-book/db6/appendices-dir/e.pdf, 17-10-2014) This database model use rules as each child has one parent and each parent can…
