the function of the database
create the database
its a unique key use to identify data in database
a key is important in a database because using of that key only we can identify a unique attribute.
An alternate key is a set of one or more attributes in a database that can uniquely identify a record, similar to a primary key, but is not designated as the primary key. Its primary function is to provide additional means of accessing data efficiently, ensuring that each record remains unique. Alternate keys enhance data integrity and flexibility in querying the database. They are particularly useful for enforcing business rules and improving search capabilities.

i key field is a field with with a key in the middle :)
There are many keys in database each having particular use. Types of keys in database are : Primary key, candidate key, alternate key, foreign key, surrogate key.
Access is a database. Records are what each set of data is, so they are a key aspect of Access and any database. So that is why the icon is like it is.Access is a database.

Microsoft Excel is not a database, it is a spreadsheet. You could use it for a rudimentary database application, but that is not it's primary function.
dataBase[0].valueline = d3.svg.line() .x(function(d) { return x(d["Date"]); }) .y(function(d) { return y(d[dataBase[0].columnline]); }); dataBase[1].valueline = d3.svg.line() .x(function(d) { return x(d["Date"]); }) .y(function(d) { return y(d[dataBase[1].columnline]); }); dataBase[2].valueline = d3.svg.line() .x(function(d) { return x(d["Date"]); }) .y(function(d) { return y(d[dataBase[2].columnline]); }); dataBase[3].valueline = d3.svg.line() .x(function(d) { return x(d["Date"]); }) .y(function(d) { return y(d[dataBase[3].columnline]); }); dataBase[4].valueline = d3.svg.line() .x(function(d) { return x(d["Date"]); }) .y(function(d) { return y(d[dataBase[4].columnline]); }); dataBase[5].valueline = d3.svg.line() .x(function(d) { return x(d["Date"]); }) .y(function(d) { return y(d[dataBase[5].columnline]); }); dataBase[6].valueline = d3.svg.line() .x(function(d) { return x(d["Date"]); }) .y(function(d) { return y(d[dataBase[6].columnline]); }); dataBase[7].valueline = d3.svg.line() .x(function(d) { return x(d["Date"]); }) .y(function(d) { return y(d[dataBase[7].columnline]); }); I am trying to make a javascript loop that would do the same, but whenever I replace the counter with the numbers, it doesn't work.
There are five types of keys in database management system . The name of the five keys are as follows .:1) surrogate key -which is the system generated primary key .2) Primary key - same function as surrogate key but user defined.3) candidate key -combination of two more keys.4) alternate keys - alternative for candidate keys.5) foreign key - primary key of another table.There are five types of keys in database management system.These five keys are surrogate, primary, candidate, alternate, foreign keys .
