Database Programming
Databases are collections of tables that maintain and display information, often collaboratively; this information can be used for interaction with an application or gaining general knowledge. Questions about database engines and modifying or using them belong in this category.

Nested macro calls refer to the macro calls within the macros. A macros is available within other macro definitions also. In the scenario when a macro call occurs, which contains another macro call, the macro processor generates the nested macro definition as text and places it on the input stack. The definition of the macro is then scanned and the macro processor complies it.
How do you draw entity relatoin in databases?
If the question is for databases, then the answer is in the link. If you want to store the ERDs in a database, then the question needs to be clarified to which database.

don't search for a dummy project or website copies, they will get rejected or low grade. as it happens to many. go legal way. byeeeeeee
That would be a query.
What is meta data in database management?
meta data can be define as the data about data....
data is the known facts which can be recorded and altered...and the info. about the data is called meta data...
example :-
Suppose in a student table student name,age,sex,class,subject,stream all are the data of the student table and the data about these data(name,age,sex, etc...) like what type of data whether it is a integer or string or char and what is the range like age should be with in o-20 like the all are called Meta Data.......
In DBMS,Schema is the overall Design of the Database.Instance is the information stored in the Database at a particular moment.In programming,you declare a variable which corresponds to "Schema".But its values changes as and when required which corresponds to "Instance".
Google about levels of Database Abstraction.
Physical Schema describes database design at physical level while a logical schema describes the database design at the logical level.A database may also have several schemas at the view level, sometimes called subschemas, that describe different views of the database.
Suggest a suitable medium for keeping back-up copies of master files?
you should probably keep them in a binder suitcase or makes 5 copies and put 2 of them in a file cabinet
Yes it is. Tables can always have more data entered into them.
Management information system- multiple choice questions with answers?

Before the official announcement of .NET, the term NGWS was used for Microsoft's plans for producing an "Internet-based platform of Next Generation Windows Services". The Microsoft. NET strategy was presented by Microsoft officials to the rest of the world in June 2000: * .NET is Microsoft's new Internet and Web strategy * .NET is NOT a new operating system * .NET is a new Internet and Web based infrastructure * .NET delivers software as Web Services * .NET is a framework for universal services * .NET is a server centric computing model * .NET will run in any browser on any platform * .NET is based on the newest Web standa

How to put out the Trojans from the computer?

Is it necessarily that a foreign key is primary key in other table?
It is not mandatory that is must be a primary key but it must be a unique key in the other table.
Econometrics research is basically research that employs statistical techniques and economic theory to quantify, analyze and test relationships between two or more variables.
Much of the time regression analysis is used to perform the research.
Say you have a data set consisting of 100 observations with two variables... Income and "Weekly Family Food Expenditure"...
Economic theory would tell you that as income increases the weekly food expenditure should increases as well, but often times that's not enough... you want to confirm that and then tell by how much and perhaps you want to know if the increase is constant at all levels. You may even want to predict what someone's food expenditure will be given their weekly income.
Through statistical and econometric techniques you'll be able to construct a model and determine how accurate it is with a certain level of confidence. You can use that model to predict food expenditures at different levels of income, measure if the increase in food expenditure that you suppose to occur with increased income is constant at all levels, determine how much of the food expenditure is described by income or if there are other variables that if added to the model might help to explain it better and much more.

The answer should be a colon : Good Luck!
Explain Clustering with respect to storage structures in databases?
In the above process, if the page containing the requested record is already in the memory, retrieval from the disk is not necessary. In such a situation, time taken for the whole operation will be less. Thus, if the records which are frequently used together, more records will be in the same page. Hence the number of pages to be retrieved will be less and this reduces the number of disk accesses which in turn gives a better performance. This method of storing logically related records, physically together is called clustering. For example, consider CUSTOMER table as shown below. Cust ID Cust Name Cust City…. 10001 Raj Delhi …. 10002 …. …. …. 10003 …. …. …. 10004 …. …. …. …. …. …. …. …. …. …. …. If queries retrieving Customers with consecutive Cust_IDs frequently occur in the application, clustering based on Cust_ID will help improving the performance of these queries. This can be explained as follows. Assume that he customer record size is 128 bytes and the typical size of a page retrieved by the File Manager is 1 kb (1024 bytes). If there is no clustering, it can be assumed that the customer records are stored at random physical locations. In the worst-case scenario, each record may be placed in a different page. Hence a query to retrieve 100 records with consecutive Cust_IDs (say 10001 to 10100), will require 100 pages to be accessed which in turn translates to 100 disc accesses. But, if the records are clustered, a page can contain 8 records. Hence the number of pages to be accessed for retrieving the 100 consecutive records will be ceil (100/8) =13. i.e., only 13 disk accesses will be require to obtain the query results. Thus, in the given example, clustering improves the speed by a factor of 7.7. * Intra-file Clustering - Clustered records belong to the same file (table) as in the above example. * Inter-file Clustering - Clustered records belong to different files (tables). This type of clustering may be required to enhance the speed of queries retrieving related records from more than one table. Here interleaving of records is used.
What is the difference between for instance and for example?
Normally Instance should be use for describe the situtaion in speaking ( formal)
Whereas example should be use for wrinting purpose.
