What is parallism in computer science?
Parallelism is running processes simultaneously to maximize resources for faster processing.
Actually, that's incorrect. Parallelism in computer science is a property of an algorithm used to solve a problem. The Parallelism of an algorithm is its ability to be broken into discrete, independent parts which can be operated on separately, then recombined to obtain the answer the algorithm was supposed to provide. The greater the number of discrete parts that the algorithm can be broken into, the higher the Parallelism.
"Parallelism" can, however, be used to characterize the ability of a processor to work on different tasks at once, in a manner analogous to that of describing the ability of an algorithm to work on different portions of a problem simultaneously.
What does the system request button do on computer?
It currently has no use. It was first introduced by IBM and was a new key so it could have no conflicts with current keys.

Importance of computerized database?
A computer database is a set of tables that contain important information that is connected together by certain important fields of data. A database could contain things such as customer records, sales information etc. You can pull information out of this database in the form of reports or queries to help you with business analysis and customer communication.
Direct Data Capture is data capture that came from a direct source
It depends on what it's for!
Megabits are a measurement of data size. Eight bits make one byte, so if you have an 8 megabit (mb or mbit) it's the same as having 1 megabyte (MB or MByte)
Beyond that, it depends ENTIRELY on what it is you are asking about. Some things you want more, others you want less, and some don't matter at all.
What is the purpose of an information sheet?
The purpose of an information sheet is to succinctly provide information on a particular topic.
What is the difference between hql and sql?
one of the difference is HQL does not support distinct but SQL supports the distinct in the query
Where can you find the best data mining company?
There is a really great data mining company that I have heard of called TunedIT.
I'm sending you general information about them!:)
TunedIT - Contest in place of exam
Traditional system of evaluation of credited tasks for students will soon become outdated. TunedIT created the contest system and platform, which enables students getting credits just from home. The new system will be beneficial both for students and for professors.
It seems that getting credits for laboratory classes does not need to be boring again. Students of computer science have to solve several assignments in their laboratory classes, which are then taken into account by their tutors when giving final grades. Usually, a student, in order to get credit has to write a program or elaborate an algorithm. It applies in particular to such lessons as "artificial intelligence", "data mining" or "self-learning systems". Generally, in the framework of these subjects, a lecturer requires from his or her students to work out an algorithm for a given problem (data set).
Most frequently, in Polish universities, as far as computer science students are concerned, they have approximately one month to prepare such algorithm. When they finish, they send it to professor in charge of laboratory classes for evaluation.
Competitions organized on TunedIT platform constitute an alternative for students' vis-à-vis traditional way of crediting. These competitions encompass identical assignments but the participants send their solutions over Internet to special Web page established for the needs of contest. Their works are immediately tested and automatically evaluated. What even more important, every student can see his or her result, instantly compare a quality of the solution with others and still have a chance for improvement. Such model of crediting may become an option for student, thus eliminating the traditional one. From didactic point of view, contests organized by TunedIT may have substantial influence upon development of students' skills because they will force the participants to actively search for the best possible solution and to learn from one's own mistakes.
Still, the TunedIT platform specializing, among others, in organization of competitions for computer science students, has in fact more functionalities. In fact, one can arrange any type of competition with a use of this particular solution. - We are able to organize practically any type of data mining assignments - says Marcin Wojnarski, the founder of TunedIT- Contest platform TunedIT is very comprehensive and gives this opportunity to organize competitions in many different fields. In fact, we can trigger on it all kinds of assignments in 'data mining', but also in other fields, like data compression.
The very first competition for students to get credits for a given assignment was arranged in May 2009. This contest was organized for the Faculty of Mathematics, Informatics and Mechanics in the University of Warsaw. Use of this platform for organization of contests for students has a lot of advantages, and university circles in Poland and abroad have become more and more interested in this very solution.
TunedIT is an international service. Our contest platform may be used in any place of the world: USA, Germany, Great Britain, not excluding even more exotic places where many young IT specialists are educated, like in India and China. - explains Wojnarski - Our users come from a dozen of countries, among others from the USA, England, India, China, Canada, Australia, Germany, New Zealand, Iran and Japan. In the scientific rivalry organized recently in TunedIT, which terminated in the end of February, triumphed the teams from China, Australia, Croatia and Japan.
One of the trumps of TunedIT platform is a complete automation of assignment evaluation system that saves time for both students and teachers. TunedIT platform offers large-scale integration between its users what contributes to competition in pursuance of the best results. Founders of this service assure that only the users have access to contest results. Data is protected by access code known solely to the participants. Hence, the inventors of TunedIT platform established the system, which saves time and provides for completely objective evaluation of tasks, thus producing fair results. These advantages may surely stimulate greater interest in this platform not only in Poland but also in the world.

List four significant differences between a file processing system and a DBMS?
1) In a traditional file processing system the work of IT was very hectic while this is not so in DBMS.2) In DBMS redundancy of data is tried to reduced while this was not so in FPS.
3) DBMS maintains data integrity but FPS do not.
What is a form view in a database?
It displays you data, usually one record at a time. It is laid out on your screen, usually with good design, proper names , making it easy for people to know what the data is referring to. You will see forms in many situations on databases and in other situations, like on a website form.
What is heap file organization?
1. Just list the records in as many blocks as necessary to hold the records.
2. Blocks are linked by pointer or table of block address.
This is called Heap file Organization.

What are data mining and predictive modeling?
Data mining refers to the study of data (usually by software without human intervention) that is generated by user behavious on the internet. For example, a visit to amazon.com and a look at books on anthropology will probably trigger amazon's software to flag one as someone interested in anthropolgy. This data is then used across the user's net experience on sites like Facebook, Game sites, etc., to show the user ads related to resources on anthropology. This is done through the use of "cookies" that are placed on the user's computer that can then be read by sites that partner with the cookie-placing site to show relevant ads.
While data mining is the first step in collecting user data, showing ads related to what the user was browsing can be redundant. Going by the previous example, if a user has already bought a book on basic anthropology, it makes little sense to show ads for the very same book. Predictive modeling goes a step or two further. Given that the user has already bought a book on basic anthropology, predictive modeling seeks to predict what the user will most likely need next and then to show ads for those products or services.
Predictive modeling uses much more of the data mined, such as the user's age, gender, known experience in the field, other related interests, etc., to build a model to predict future needs and to thus show ads tailored to those needs.
When importing an access database table Excel does what?
It will put the fields in Access into columns in Excel, and records in Access will be in rows in Excel. Data will be converted to appropriate data types.
Difference between relational model and hierarchical model?
The relational model isolates data by object and identified references (foreign keys) to those objects. This is usually captured in a table with multiple attributes (columns). The foreign key is a data value that refers to another data object (another table) which has its primary key as the other object's foreign key. The virtue in this is summarized in Dr. Dodds data normalization theorems.
Hierarchical modeling takes the normal model and summarizes it in a tree. In effect we take a cartesian join. This is usually done in datawarehousing. This is important because we begin to look at layers of the object model rather than views of the data store. Aspect analyiss of the data in hierarchical models depends on the tree structure and is focused on each data object. The tree model contains objects that are replicated.
Each have completely different benefits when coming to the mechanics of persistence and indexing. The true model is to identify what I've called the DATA TRIANGULATION MODEL where data consumption (often GUI or reports or reference calls), persistence, and prominence are characterized. Choice of mechanics between which is most useful comes from these three elements. We realize this model is incomplete as there is the OOD and list theorems that can corrupt the DATA TRIANGULATION MODEL.
We return to mechanics at this point because that is what limits us. IOPS, persistence, availability, durability, and supercalifragilisticexpialidociousability. -cja stopher2@gmail.com
