NULL Value Concepts
When making tables, if one row is not able to provide a data value for a column, the value is referred to as
null. Columns of any type of data could contain null values, unless the column was specified as non
Null at the time that the table was set up.
The Principles of NULL Values
1. The setting of a null value is suitable when the exact value is not known or when a value is not known.
This would not be relevant.
2. A null value isn’t equivalent to a zero value.
3. Null values will be evaluated as null for any given expression. e.g. Null multiplied 10 times is null.
4. If a column’s name can be declared to be not null, that column is deemed to be mandatory.
column. This implies that users will be compelled to input information into that column. This implies that the user must enter data into that.
Principal Concepts Argentina  Email List
Primary keys are one or more columns within the table that are used to identify every row of the table.
Primary key values cannot be null or invalid and have to be distinctive across columns.
A multicolumn primary key can be known as a composite primary key. The sole function that is a primary key performs is to
The function of key is to identify a row, and in the event that a particular column is used, it will be as effective as when
Multiple columns are employed. The use of multiple columns i.e. (composite key) are only used when needed.

The unique key functions identical the primary keys but the primary reason behind an distinctive key is guarantee that

At the time of cell’s creation, the default value can get assigned. If users are loading the cell, a
“record” with values, and then leaves the cell empty and the DBA will load the cell using the

Foreign keys represent relationships between tables. Foreign keys are column (or an entire group of
columns) with values that derive by the key of the table or another table.

In this case, we need to specify the assignments of tuple value to free variables are in this definition.
formula makes the formula prove as true.
An evaluation of a query takes place using an individual data source. Let each variable free in a formula F
tied to a tuple value. The given assignment assigns tuples to variables according to the given
Database instance, F is (or simply “is”) true if any of the following applies:
1. It is anatomic equation R Rel which is assigned to R a tuple in context of the relation Rel.
2. F is a comparator R.a O.p S.b, R.a op constant or constant in R.a as well as the Tuples that are assigned
R S and S contain field value R.a and S.b which make the distinction true.
3. It is of form -p, and Q is not true either of pq, and both p and Q are true or of the form p q, or
Form p q which is one that’s true or in the form pq and Q is true if it is true.
4. F is the formula R(p(R)) and there is an assigning of tuples to variable variables that are free in p(R),
which includes the variable R which results in that formula p(R) real. Argentina  Email List
5. F is the formula R(p(R)) and there is an assigning of tuples variables that are not free in p(R)
which creates that formula p(R) to be true regardless of the tuple assigned to R.

The term “domain variable” refers to one that is a variable that has a range of value of a particular characteristic (e.g.,
the variable could get an integer value if it is in an attribute with a domain that is the set of
intergers). Intergers). DRC query is of the form{ ” | P ( ), where each|(), where each|=, where every} xi is
whether a variable in the domain, or an arbitrary constant, p ( ) denotes|”” refers to|”” denotes} the DRC formula that has
Only free variables are variables in the xi, 1 i. The outcome of this search can be described as the set
All the tuples where the formula is deemed to be true.
The DRC formula has been defined in such a way which is quite like the definition of TRC formulas. TRC formula.
The major change lies in that these variables now are domain variables. Let op denote an operator in
The set the set,, and let X as well as Y become domain variables.
An atomic formula used in DRC can be described as:
1. x1, ,=”” .=”” x2 ,=”” xn =””> Rel where Rel is a relationship with an n attribute, where each xi, one or n could be one or the other.

Put P. beneath the name for the relationship. This is similar to that of the SELECT * convention used in SQL.
