3. Create the program specifications. DEFINE DATA REQUIREMENTS I have created preliminary contents lists for important groupings of data identify as develop the model DFD. These are proved to be very useful during the database design while I used these lists. CREATE A SYSTEM STRUCTURE CHART The system structure is used to show all the processes of system.
2.1 PEOPLE RESOURCES The Computer-Based Information System (CBIS) is important to the people because the people are needed every elements in CBIS to make it be useful. The element in CBIS component that can influence the success or failure of the information system. The people resources like end user and Information System Specialist, System Analyst, Programmers, Data Administrators and so on. End user is also called as users or clients are the people use the information system or the information procedure. They can be the engineers, accountants, manager, customers, and so on.
The standard acronym for database management system is DBMS, so you will often see this instead of the full name. The ultimate purpose of a database management system is to store and transform data into information to support making decisions. A DBMS consists of the following three elements: 1. The physical database: the collection of files that contain the data 2. The database engine: the software that makes it possible to access and modify the contents of the database 3.
As in-house servers are not scalable thus company is responsible for costs associated with renewing software license and hardware upgrades.There is great risk of hardware failure so there is possibility of loss of data Another demerit for these companies is security issue. As people can steal the hardware so they have to protect the hardware physically. So in accordance with these cons of In-house servers it is better for these companies to implement the cloud computing technonolgy.These companies can use any of the categories of cloud computing PAAS, IAAS or SAAS. By using this technology they can store data and records of their clients and staff virtually and can access them from anywhere. Cloud computing has a beneficial effect on organisations as interior designing Companies will be able to measure and pay for only the IT resources they consume,for storage of data and increase or decrease their usage to match requirements and budget.
Every company or organization needs places to store their institutional knowledge and data such as personally identifiable data, employee human resource data, financial data and etc. Nowadays all this institutional knowledge and data are being stored on the companies database. So, the security and confidentiality of this data is a critical importance. Database security can be defined as the protection of data and information that is stored in a database. According to  database security primarily ensures the confidentiality, availability and integrity of the information contained in a database.
Teradata is a fully scalable relational database management system produced by Teradata Corp. It is extensively used to manage large data warehousing operations. The Teradata database system is based on off-the-shelf symmetric multiprocessing technology combined with communication networking, connecting symmetric multiprocessing systems to form large parallel processing systems. Teradata is an open system, running on a UNIX MP-RAS or Windows server platform. It is capable of supporting many concurrent users from various client platforms.
SOFTWARE TESTING Testing is the most important part of a software development. In the life cycle of software development, there are a number of test phases which the software or the application is undergone. Software testing provides an independent view and an objective of the software. It is done for the business to understand and appreciate the software implementation risks. Testing is carried out by a set of professional testers who are appointed for the purpose.
One limitation of COMINT is that communication has to exist in order to be intercepted. Without communications, the COMINT operation is worthless. Information can also be encoded, which will pose a problem in analysis. One limitation of using COMINT is that there is too much information. Communication intelligence yields a lot of information for intelligence analysts.
Can a Data Mining system generate only interesting patterns? It is an optimization problem in Data Mining. it is highly desirable for data mining systems to generate only interesting patterns. This would be much more efficient for user and data mining systems, because neither would have to search through the patterns generated in order to identify the truly interesting ones. Major Issues in Data Mining: Mining different kinds of knowledge in database: Because different users can be interested in different kinds of knowledge.
