But it's way too early to rejoice, as our hero decides to stay in Bucharest to sabotage her daughter's career. Winfried adopts the fictional identity of Toni Erdmann, an imaginary business coach allegedly working for a big shot in town, and proceeds to tail her daughter's every move and appointment in an escalation of hilarious set-pieces.

While laughing out loud the audience gets a glimpse into a much-maligned but very abstract world which the director frames in all its unremarkable mediocrity and tedious luxury. Corporate hedonism next to Winfried's exuberance and impropriety appears as nothing more than a disappointing, material consolation.

His actions are aimed at the reactivation of the emotions Ines seems to have anesthetized as part of her job description. However inappropriate it may be, Toni Erdmann's sabotage of her career is clearly an act of love that for a moment, though the film remains fruitfully ambiguous, insinuates in Ines the possibility of self-esteem outside of work. His attempt to re-connect with his daughter through pranks is by no means childish nor ludicrous, it is a genuine and partially successful effort to replace formality with emotional substance, profit with feelings.

Not the easiest of endeavors, admittedly. Their relationship also evinces the backward generational gap that divides the '68 generation from their children who came of age in a world where the only alternative to a corporate life is unemployment. All this takes place under the prodigious direction of Maren Ade, who made a historic film which effortlessly mixes family drama and screwball comedy, graced by the naturalistic accuracy of a bio-political documentary.

Nothing as far as moving images are concerned has managed to give a meaningful shape to the systemic crisis that has invested Europe and its illusions like this film. Acting reaches sublime heights in the spontaneous rigor of an ensemble performance where the most subtle and strenuous emotions are made tangible. The hug Ines gives her father is the stuff heartbreaks are made of, as their conflicted relationship exceeds its private dimension to become the existential allegory of a collapsing system.

Ines' ill-concealed irritation measured against her father's puckish smile is the picture of a family we all belong to. That the director managed to illuminate the continental tragedy of austerity and its measures with laughter, without the need to raise the sociological finger, is nothing short of miraculous. Toni Erdmann in fact is a film from which we can start, however belatedly, to reconsider the endless potential of cinema in the life of a continent that, after succumbing to capitalist fundamentalism, is once again facing the very realistic threat of fascistic totalitarianisms.

A cinema that can be urgent and subversively entertaining at the same time, where form and content are not theoretical excuses but practical contingencies. Let's look at a generic example of this type of relationship. This is by far the most common relationship that exists between a pair of tables in a database, and it is the easiest to identify.

It is crucial from a data-integrity standpoint because it helps to eliminate duplicate data and to keep redundant data to an absolute minimum. A typical example of a one-to-many relationship. Diagramming a one-to-many relationship.

Note that the crow's foot symbol is always located next to the table on the "many" side of the relationship. Many-to-Many Relationships A pair of tables bears a many-to-many relationship when a single record in the first table can be related to one or more records in the second table and a single record in the second table can be related to one or more records in the first table.

This is the second most common relationship that exists between a pair of tables in a database.

It can be a little more difficult to identify than a one-to-many relationship, so you must be sure to examine the tables carefully.

Problems with Many-to-Many Relationships A many-to-many relationship has an inherent peculiarity that you must address before you can effectively use the data from the tables involved in the relationship. The issue is this: How do you easily associate records from the first table with records in the second table in order to establish the relationship? This is an important question because you'll encounter problems such as these if you do not establish the relationship properly: It will be tedious and somewhat difficult to retrieve information from one of the tables.

One of the tables will contain a large amount of redundant data. Duplicate data will exist within both tables.

It will be difficult for you to insert, update, and delete data. There are two common methods that novice and inexperienced developers use in a futile attempt to address this situation. Note As this example unfolds, keep in mind that every many-to-many relationship you encounter will exhibit these same issues. As you can see, there is no actual connection between the two tables, so you have no way of associating records in one table with records in the other table.

The first method you might use to attempt to establish a connection involves taking a field from one table and incorporating it a given number of times within the other table. This approach usually appeals to people who are accustomed to working with spreadsheets. Do these structures look vaguely familiar? All you've done using this method is introduce a "flattened" multivalued field into the table structure.

In doing so, you've also introduced the problems associated with a multivalued field. If necessary, review Chapter 7. Although you know how to resolve a multivalued field, this is not a good or proper way to establish the relationship.

The second method you might attempt to use is simply a variation of the first method. In this case, you take one or more fields from one table and incorporate a single instance of each field within the other table.

This may seem to be a distinct improvement over the first method, but you'll see that there are problems that arise from such modifications when you load the revised STUDENTS table with sample data.

The table contains unnecessary duplicate fields. You learned all about unnecessary duplicate fields and the problems they pose back in Chapter 7, so you know that using them here is not a good idea. There is a large amount of redundant data. It is difficult to insert a new record. This will automatically trigger a violation of the Elements of a Primary Key because the primary key cannot be null; therefore, you cannot insert the record into the table until you can provide a proper primary key value.

It is difficult to delete a record. This is especially true if the only data about a new class has been recorded in the particular student record you want to delete. Note the record for Diana Barlet, for example. If Diana decides not to attend any classes this year and you delete her record, you will lose the data for the "Introduction to Database Design" class. Fortunately, you will not have to worry about any of these problems because you're going to learn the proper way to establish a many-to-many relationship.

Self-Referencing Relationships This particular type of relationship does not exist between a pair of tables, which is why it isn't mentioned at the beginning of this section. It is instead a relationship that exists between the records within a table.
