Name for trading and manufacturing companies.
The heads of trading companies rarely think about the correct name of their own business. Today they sell soap, and tomorrow they sell pumps. Therefore, in the market you can often find an example when a company called "Argo" sells oil products. Trade managers prefer to borrow their firm's name from their supplier or manufacturer of goods to whom they distribute. At the same time, they add the name of their region to the name. Yes, and other prefixes: wholesale, trade, bargaining, supply, sales, investment - there are enough in the names.Manufacturing companies have a different naming style. They inherited the factories from Soviet times, and as a rule, they are run by former engineers. Technicians are very fond of abbreviations, by which it is quite difficult to understand what NMZ is - Nizhny Novgorod Mechanical Plant or Nizhny Tagil Mechanical Plant. Soviet production names still dominate the market for business products. Of course, there is no point in changing names like VAZ, GAZ or KAMAZ. But other electrical or mechanical industries should think about separating themselves from the gray mass of turning and locksmith shops.

Relational calculus with domain variables
The main formal difference between domain calculus and tuple calculus is the presence of an additional set of predicates that allow one to express the so-called membership conditions. If R- it n-ary relation with attributes t1 , t2 , ..., tn, then the membership condition has the form
R (pair, pair,… ),
where each pair pair has the form t:v, wherein v – it is either a literal constant or a domain variable name. Membership condition takes on a value true if and only if, with respect to R there is a tuple containing the values of the specified attributes. If v- constant, then on attribute t a strict condition is set that does not depend on the current values of domain variables; if v- name of a domain variable, then the membership condition can take on different values for different values of this variable. For example, evaluating the expression
PD (PNOM:"P1", DNOM:"D1")
gives value true, if and only if there is a tuple with the value of PNOM equal to P1 and the value of DNOM equal to D1 in relation to the PD. Likewise, the membership condition
PD (PNOM:PNOMA, DNOM:DNOMA)
evaluates to true if and only if there exists a tuple with a value of PNOM equivalent to the current value of the domain variable PNOM (whatever) and a value of DNOM equivalent to the current value of the domain variable DNOM (again, whatever) .
In all other respects, domain calculus formulas and expressions look similar to tuple calculus formulas and expressions. In particular, of course, free and bound occurrences of domain variables are distinguished.
Further, we will assume that there are domain variables with names formed by adding the numbers 1, 2, 3, ... to the corresponding domain names. In addition, in the supplier and parts database, each attribute is assumed to have the same name as its corresponding domain, with the exception of the PFAM and DNEL attributes, for which the corresponding domain is simply named NAME.
For example, the expression
(PNOM1) WHERE SUPPLIER (PNOM:PNOMA,
Voronezh city")
means a subset of all supplier numbers from the city of Voronezh.
Using the traditional syntax of the predicate language, the relational calculus with domain variables is:
{x 1 x 2 … x k | ( x 1 , x 2 , … , x k)},
where is a formula that has the property that only its free domain variables are distinct variables x 1 , x 2 , … , x k .
The domain relational calculus is the basis of most form-based query languages. In particular, the well-known language QBE (Query-by-Example) is based on this calculus, which was the first (and most interesting) language in the family of languages based on tabular forms.
Examples
SELECT DISTINCT S.SNAME
WHERE NOT EXISTS
WHERE SP.S# = S.S#
AND SP.P# = "P2") ;
Or alternative wording:
SELECT DISTINCT S.SNAME FROM S
WHERE S.S# NOT IN
WHERE SP.P# ="P2" ;
8.3.16. Get the names of suppliers supplying all parts
See chapters 6 and 7 for similar examples.
SELECT DISTINCT S.SNAME
WHERE NOT EXISTS
WHERE NOT EXISTS
WHERE SP.S# = S.S#
AND SP.P# = P.P#)) ;
The SQL language does not include any direct support for the universal quantifier forall; therefore, queries like forall are usually expressed through the negation of existential quantifiers, as in this example.
It is worth noting that expressions such as the one just shown, while somewhat intimidating at first glance, are easily constructed by users familiar with the relational calculus, as noted in . Or, on the other hand, if these examples still seem too complicated, then there are several "workarounds" that will help you avoid using negative quantifiers. In our case, for example, we can write:
SELECT DISTINCT S.SNAME
WHERE(SELECT COUNT(SP.P#)
WHERE SP.S# = S.S#) = (SELECT COUNT (P.P#)
("names of suppliers for whom the quantity of supplied parts is equal to the quantity of all parts"). However, pay attention to the following circumstances.
First, the last statement assumes, unlike the not exists statement, that there are no part numbers in relation to SP that are not contained in relation to P. In other words, the two statements are equivalent (and the second is correct) only because of the operation integrity constraints.
Second, the method used in the second formulation (comparing two quantities) was not originally supported by SQL and was added to the SQL/92 standard. It is still not supported in many products.
Note also that in fact it would be better to compare two tables(see the discussion of relational comparisons in Chapter 6) and the query would then be written like this:
SELECT DISTINCT S.SNAME
WHERE (SELECT SP.P#)
WHERE SP.S# = S.S#) = (SELECT P.P#
Since the SQL language does not directly support comparisons between tables, it is necessary to resort to a trick using cardinal number comparison (number of rows) of tables (based on practical experience, we make sure that if the cardinal numbers of tables are the same, then the tables are the same, at least in case under discussion).
Contact your ISP (Bell, Rogers, Wightman) to use their service. While you are setting up your phone account, the account manager must provide you with a username, phone number, and password. This is because this way you can safely access the Internet.
Make sure your computer is connected. Connect the phone cord to the back of the computer to the phone jack on the wall of the room you are in. Turn on your PC.
Go to the control panel. After the computer boot process is complete, you should be taken to the main desktop page. You will also see various icons. Look for an icon called "My computer". Enter it. After logging in, you will notice a small square bar on the left side of the screen labeled "Other places". This panel contains 4 links that you can click on. Click on the one that stands for "Control panel" (Control panel).
Go to network connections. The control panel contains various icons. It allows you to change your computer's settings, such as: adding new software to the PC, changing the mouse icon, adding a new user to the computer, or in this case creating/editing your account on the Internet. From the Control Panel, look for an icon called "Network connections". Double click on it to enter.
Create a new connection. In the screen that opens, you will not see almost anything. Looking at the top left side of the screen, you will see a small square panel called "Network tasks". In this panel there is a link "Create a new connection" (Create a new connection). Click on it.
A small window will appear, you just click the "Next" button once.
Now you can click on one of the 3 options. Select the one that says "Set up my connection manually". Click the "Next" button.
Another list of 3 options will appear. Select the "Connect using a dial up modem" option, then click the "Next" button.
You will now be prompted to enter the name of the ISP. You can name the connection whatever you want. (For example, your first name, last name, nickname) Enter the service provider name of your choice and click the "Next" button.
You will now be asked to enter a phone number (the number you dialed should match the number you received from support when you set up your account in step #1). Enter your phone number and click the Next button.
