...The definition I have determined that defines a data type is different types of data that will include a range of value or a specific type of data in a storage formant. A variable that is stored as data in a computer program has to be a specific data type. There are many different types of data that includes dates, values, numbers, and characters to name a few. Different data types can be used by a large number of database applications. A specific kind of data is usually required in certain fields of a database. For example, if a business has a database for all the employees a different data type would be used for each kind of data. The start date for an employee could be stored in a date format, but a wage/salary amount would be stored as an integer. If database types are kept the same in all the records then the applications are easily search, compare, and sort different records. Data typing is important if you want to keep a business managed. Data entry is important because it is a way of organizing data that keeps a business well managed. Data entry is very important if you want to manage information and records in a computer software program. Data entry assures accuracy of company’s data and all information keeps up to date. Accuracy is very important in data entry validation. Validation of data entry will reduce the problems of inaccuracy if incorrect data is input. When creating a data entry the format for each field can input. The date, time, number, character, etc...

...John Smith C257 Task 1 Data aggregation as it pertains to healthcare is the collection of health data from individual health records that are then grouped into a collective database that can be further analyzed and used for research. This data does not identify individual patients, but instead focuses on groups of patients which are then used for research purposes such as finding linking factors that could be the cause of certain illnesses. Also by having multiple sources for this data allows more statistical validity when determining these factors. Data aggregation is not only beneficial in this aspect, but can also be used to improve consumer transparency by allowing patients access to provider quality evaluations through multiple different sources. Although data aggregation can be beneficial for future and present healthcare issues, it is not without its faults. For instance in order to have a truly unified database, it would take multiple companies and industries working together to make this happen. Also at this point the suspicion about data aggregation and how it will ultimately be used is still an issue. In an article by Regan and Randall-Lewis (2008) there is a question posed “Is data being used to either reform the healthcare system or “out think” your rivals?” which asks whether this data will be used to find health trends that will lead to the betterment of society’s healthcare or the financial gain of a company. Lastly the security risks involved with having...

...to allow retrieval and manipulation of values within our programs 12. A SELECT statement within a PL/SQL block must include an INTO clause to indicate the variable/s that will hold the data being retrieved. The INTO clause follows the SELECT clause and precedes the FROM clause. In addition, a SELECT statement that returns no rows will raise an Oracle error. 13. The %TYPE attribute is used to declare the data type of a variable based on the data type of a database table column. The data type declaration must include the table and column name in the form: tablename.columnname%TYPE. 14. The %ROWTYPE attribute is used to declare the data type of a record variable based on the row structure of a table. The data type declaration must include the table name in the form: tablename%ROWTYPE. 15. Composite data types allow the creation of a variable that can hold multiple values with various data types as a single unit. Examples include a record and a table of records.

...enumerations and type definitions. Naming: The variable name is the way to reference the stored value. It allows the name to be used independently of the exact information it represents. Assignment: It sets or re-sets the value stored in the storage locations marked by a variable name. It copies a value into the variable. Assignments allow a variable to hold different values at different times during its life span and scope. Although, some languages do not allow that kind of “destructive” reassignment because it could imply changes of non-local state. and Initialization: The process of locating and using the defined values for variable data that is used by a computer program. The operating system or application is installed with default or user-specified values that determine certain aspects of how the system or program is to function. These values are stored in initialization files. When the operating system or an application program is first loaded into memory, a part of the program performs initialization, finds definite values to substitute for variable values, and acts accordingly in program designs. Use the correct data type for variables in program designs. Variables are “placeholders” used to store values that have names and data types. The data type of a variable determines how the bits representing those values are stored in the computer’s memory. When you declare a variable, you can also supply a data type for it. All variable have a data type that determines what...

...Week 2 Assignment Grayson Wimmer 1. What is the simplest SQL retrieval? SELECT 2. What is the purpose of the Where clause when using SELECT? The WHERE clause is used to extract only those records that fulfill a specified criterion. 3. What are data types and why are they important? A data type is a classification identifying one of various types of data, they are important because assigning data types gives meaning to collections of information 4. Provide an example of the GROUP by clause, when would you use this clause? SELECT Salesperson, SUM(Revenue) AS ‘Total’, MIN(Revenue) AS ‘Smallest’, MAX(Revenue) AS ‘Largest’, AVG(Revenue) AS ‘Average’, COUNT(Revenue) AS ‘Number’ FROM Orders GROUP BY Salesperson You use this clause when you need to see the information in a certain order 5. What is an aggregate function (provide 4)? How are they used? An aggregate function is a function where the values of multiple rows are grouped together as input on certain criteria to form a single value of more significant meaning or measurement AVG() - Returns the average value (average) COUNT() - Returns the number of rows (count) FIRST() - Returns the first value LAST() - Returns the last value 6.

...Implementation of Quality Information Systems for E-Learning Applications Abstract: Quality information systems (QIS) are providing all the quality-relevant information during the whole life cycle of a product to all the people involved. With regard to e-learning applications this means that a QIS should provide quality-relevant information to the authors of e-learning materials as well as to the instructors and the learners using them. In this work it is described how such a QIS can be implemented in the context of e-learning applications. In this connection a prototypic system design and strategies for the integration of a QIS into the information system infrastructure of e-learning providers are presented. 1 Introduction Many concepts of quality management are not only applicable during the production and usage of material products, but also in the context of immaterial ones - like for example e-learning applications. Nevertheless quality management concepts are hardly used in this regard today. As a basis for quality management so-called quality information systems (QIS) can be used. They are providing all the quality-relevant information during the whole life cycle of a product to all the people involved. In the context of e-learning this means that a quality information system should provide all the quality-relevant information to the authors of e-learning materials, to the instructors and tutors, and also to the learners.

...Difference between C++ and JAVA:- 1. Java has no preprocessor. If you want to use classes in another library, you say Import and the name of the library. There are no preprocessors-like macros. 2. there are no pointers in the sense of C and C++. When you create an object with new, you get back a reference. 3. there are no destructors in Java. There is no “scope” of a variable per seen, to indicate when the object’s lifetime is ended-the lifetime of an object is determined instead by the garbage collection. 4. There is no GOTO statement in JAVA. 5. No INLINE methods. The java compiler might decide it’s own to inline a method, but you don’t have much control over this. You can suggest inlining in java by using FINAL keyword for a method. However , inline functions are only suggestions to the C++ compiler as well. 6. Java has method overloading that works virtually identically to C++ function overloading. 7. Java doesn’t create exe file after the execution of a program. 8. 9. > In Java, the sizes of int, long etc. are rigidly defined in terms of 10. > bits. In C++ they are platform−dependent. 11. > 12. > In Java, the JVM behaves at if it were big endian, even if internally 13. > it is actually little−endian.
