Motor planning basically consists in recovering, from sensorimotor memory, the temporal and spatial specifications place and manner of articulation invariant of the phones and their sequential organization.

Therefore, during motor planning, there is access to the specific articulator motor plans, not muscle-specific, resulting in an adaptation of the spatial specifications to the phonetic context and the phone production rate, and an adaptation of the temporal specifications to the duration of sound, to the potential coarticulation and to the interarticulatory synchronization, always within the limits of equivalence.

As a logical entity, a file enables you to divide your data into meaningful groups, for example, you can use one file to hold all of a company's product information and another to hold all of its personnel information. As a physical entity, a file should be considered in terms of its organization.

The term "file organization" refers to the way in which data is stored in a file and, consequently, the method s by which it can be accessed.

Patterns of Organization

A sequential file is one in which the individual records can only be accessed sequentially, that is, in the same order as they were originally written to the file. New records are always added to the end of the file.

Record sequential files are nearly always referred to simply as sequential files because when you create a file and specify the organization as sequential, a record sequential file is created by default.

The primary use of line sequential files which are also known as "text files" or "ASCII files" is for display-only data. Most PC editors, for example Notepad, produce line sequential files.

Index sequential file organization - File organization - Advanced data structures

In a line sequential file, each record in the file is separated from the next by a record delimiter. The record delimiter, which comprises the carriage return x"0D" and the line feed x"0A" characters, is inserted after the last non-space character in each record.

A READ statement removes the record delimiter and, if necessary, pads the data record with trailing spaces to the record size defined by the program reading the data. Printer sequential files are files which are destined for a printer, either directly, or by spooling to a disk file.

They consist of a sequence of print records with zero or more vertical positioning characters such as line-feed between records. A print record consists of zero or more printable characters and is terminated by a carriage return x"0D". With a printer sequential file, the OPEN statement causes a x"0D" to be written to the file to ensure that the printer is located at the first character position before printing the first print record.

The WRITE statement causes trailing spaces to be removed from the print record before it is written to the printer with a terminating carriage return x"0D". A relative file is a file in which each record is identified by its ordinal position within the file record 1, record 2 and so on.

This means that records can be accessed randomly as well as sequentially. Because records can be accessed randomly, access to relative files is fast, but if you need to save disk space, you should avoid them because, although you can declare variable length records for a relative file, the system assumes the maximum record length for all WRITE statements to the file, and pads the unused character positions. This is done so that the COBOL file handling routines can quickly calculate the physical location of any record given its record number within the file.

As relative files always contain fixed length records, no space is saved by specifying data compression. In fact, if data compression is specified for a relative file, it is ignored by the Micro Focus File Handler. Each record in a relative file is followed by a two-byte record marker which indicates the current status of the record.

The status of a record can be:. When you delete a record from a relative file, the record's record marker is updated to show that it has been deleted but the contents of a deleted record physically remain in the file until a new record is written. If, for security reasons, you want to ensure that the actual data does not exist in the file, you must overwrite the record for example with space characters using REWRITE before you delete it.

The example code above defines a relative file. The access mode is random and so a relative key is defined, relfil-key. For random access, you must always supply a record number in the relative key, before attempting to read a record from the file. An indexed file is a file in which each record includes a primary key.It is one of the simple methods of file organization.

This can be achieved in two ways:. In the diagram above, R1, R2, R3 etc are the records. They contain all the attribute of a row. Similarly R1, R2, R3 etc can be considered as one full set of attributes.

Reading Time - 4 mins. Sequential File Organization It is one of the simple methods of file organization. This can be achieved in two ways: Records are stored one after the other as they are inserted into the tables.

This method is called pile file method. When a new record is inserted, it is placed at the end of the file. In the case of any modification or deletion of record, the record will be searched in the memory blocks.

Once it is found, it will be marked for deleting and new block of record is entered. Inserting a new record: In the diagram above, R1, R2, R3 etc are the records. In the second method, records are sorted either ascending or descending each time they are inserted into the system. This method is called sorted file method. Sorting of records may be based on the primary key or on any other columns. Whenever a new record is inserted, it will be inserted at the end of the file and then it will sort — ascending or descending based on key value and placed at the correct position.

In the case of update, it will update the record and then sort the file to place the updated record in the right place. Same is the case with delete. Array Interview Questions.

The models are: 1. Pile Access File Organisation 2. Sequential Access File Organisation 3. Indexed inverted Access File Organisation 4. Indexed Sequential Access File Organisation 5. Direct Access File Organisation 6. Multi-Ring Access File Organisation.

This method of storing records is adopted when it is not possible to arrange the records in any logical order, when the fields of the record are not well defined and the exact usage of the file cannot be anticipated. Files are generally created in this mode by punching the documents in the order they arrive.

The pile so created may be then organised into another made. Location of a record in a pile file can be done by sequentially searching the records till the desired value of the key attribute is reached.

Addition of new records in a pile file is very simple. New records are added at the end of the file. Changes and deletions of records in pile file stored on random access media can be done by locating the record and changing its contents or flagging the record to indicate that the record has been invalidated. The file may be reorganized periodically to remove the holes created by the deletion of records.

However, updating of the pile file on sequential access media can be done only by creating a new file. In sequential organisation, record occurrences are referenced in the order that they are stored physically. Data stored on cards and tapes are necessarily stored sequentially.

Direct access devices such as disks may be, but are not necessarily referenced sequentially. Sometimes the processing is best done through sequential access, even when direct access devices are used. Such is the case when many records of a file must be accessed to satisfy a request for data.

In a sequential file, records are maintained in the logical sequence of their primary key values.This method is the easiest method for file organization. In this method, files are stored sequentially. This method can be implemented in two ways:. Suppose we have four records R1, R3 and so on upto R9 and R8 in a sequence. Hence, records are nothing but a row in the table. Suppose we want to insert a new record R2 in the sequence, then it will be placed at the end of the file.

Here, records are nothing but a row in any table. Suppose there is a preexisting sorted sequence of four records R1, R3 and so on upto R6 and R7. Suppose a new record R2 has to be inserted in the sequence, then it will be inserted at the end of the file, and then it will sort the sequence.

Pile File Method: It is a quite simple method. In this method, we store the record in a sequence, i. Here, the record will be inserted in the order in which they are inserted into tables.

In case of updating or deleting of any record, the record will be searched in the memory blocks. When it is found, then it will be marked for deleting, and the new record is inserted. Insertion of the new record: Suppose we have four records R1, R3 and so on upto R9 and R8 in a sequence. Sorted File Method: In this method, the new record is always inserted at the file's end, and then it will sort the sequence in ascending or descending order.

Sorting of records is based on any primary key or any other key. In the case of modification of any record, it will update the record and then sort the file, and lastly, the updated record is placed in the right place.

Insertion of the new record: Suppose there is a preexisting sorted sequence of four records R1, R3 and so on upto R6 and R7.The Sequential file organization is a popular file organization in the database management system DBMS. It is a simple technique for file organization structure. This technique stores the data element in the sequence manner that is organized one after another in binary format.

The File organization in DBMS supports various data operations such as insert, update, delete, and retrieve the data.

Sequential File Organization

The file store the unique data attributes for identification and that helps to place the data element in the sequence. It is logical sequencing in computer memory that stores the data element for the database management systems. The sequential file organization is one of the categories among various file organizations types. There are two commonly used methods available for organizing the data element in the file storage.

sequential organizations

The methods are useful to manage and process the data store for sequential file organization. It is a standard method for sequential file organization in which the data elements are inserted one after another in the order those are inserted. And in case of a new record being inserted, it is placed at the end position of the file that is after the last inserted data element or record.

In the scenario of data modification or data deletion operation, the particular data element is searched through the sequence in the memory blocks, and after it is found, the update or deletion operation applied to that data element. Also, for the delete operation, the identified data element is marked for deletion and the new block of the record is inserted. We will discuss the insert operation to demonstrate the pile file method in the sequential file organization using an example scenario.

The pile file method is represented with the insert of a new record scenario in figure 1. We have represented each data element as one memory block such as R1 for the 1st data element, R4 is the second data element, and the R2 is the last data element of the file. Once a new data element named R6 is inserted into the file structure, It will be placed and stored after the R2 and it is the end of the file position.

Figure 1. The Sorted file method is another popular method for sequential file organization in the database management system. This method provisions the data element to be arranged and stored in the shorted order.

The data elements are stored as ascending or descending order based upon the primary key or any other key reference. In the case of the shorted file method scenario, the new data element or the new record is inserted at the end position of the file. After the inserting step, It then gets shorted in the ascending or the descending order based upon the key.

For the update or data modification scenario, the data element is searched, and updated based upon the condition. And, after the update operation completes the shorting process happens to rearrange the data elements, and the updated data element is placed at the right position of the sequential file structure.

Similarly, for deletion operation, the data item is searched through the shorted sequence, and mark as delete once it gets identified. After the delete operation completes the other data elements are get shorted and rearranged again with the original ascending or descending order.

We will discuss the insert operation to demonstrate the shorted file method in the sequential file organization using an example scenario. Let us assume, there is a sequential file contains R1, R3, Rn, R7 data elements and are present in ascending order based on the primary key reference. A new record R2 is inserted after R7 that is the end of the file position and all the records are shorted and R2 is placed one the second position after the record R1.

IN this section, we will discuss some of the advantages and the disadvantages of the sequential file organization from the uses, efficiency, and resource dependency aspects. The sequential file organization is the basic form of data storage techniques that are useful for large volumes of data storage and processing systems.

The sequential file organization that holds the named collection of information on the secondary storage like the magnetic disk, optical disks, and magnetic tables in the sequential order.

Top 6 Models of File Organization (With Diagram)

See what Fury's Fight Picks Premium members have to say about the service. Looking ahead, even one year, can be very tricky. Last year we predicted EVs and PHEVs in China to continue their boom. Pure electric car sales were the bulk of that volume with 208. We also predicted two disappointments for 2016: DS and Volkswagen.

VW has launched 3 new nameplates in 2016: the Sportsvan has outsold its rival BMW 2-Series by almost 3-to-1, the Phideon is more of an image booster than a volume model at 800 monthly sales, but the C-Trek is the most promising with 5.

The American SUV brand could easily have been mentioned among our success stories of 2016, as it has sold well over 100. That puts the brand ahead of Cadillac, which did get a mention as one of the most successful brands in China last year.

But the reason for holding off and predicting even more success for Jeep in 2017 is the launch of the new generation Compass early this year. The previous generation Compass (and Patriot) have been the best selling import models in China, and starting local production will only add to that success.

Absolutely, but not irrealistic. In its home market, Geely wants Volvo to become a full-blown rival to the German luxury brands Audi, BMW and Mercedes-Benz, but it has a long way to go in terms of volume.

This strategy intended to give those local companies the opportunity to learn from their foreign partners and help to the technology to develop their own brands and models.

The best examples of such troubled state-owned automakers are FAW, Chery and SAIC with its Maxus, MG and Roewe brands. Lastly, Shanghai Automotive Industry Corporation has got Joint Ventures with the two largest manufacturers in China: Volkswagen and General Motors, but sales of its own brands Roewe, MG and Maxus were less than 300.

These brands will continue to gain market share at home, at the cost of their competitors who can sit back and rake in the profits by producing cars for their overseas partners. What are your predictions for 2017. Which brand or model do you expect to surprise or disappoint this year.

Let me know in the comments below. His daily driver is an Alfa Romeo GT 3. You can find all his articles Here. In a few year China will be able to end the mandate for foreign automakers to form Joint Ventures with local manufacturers if they want to produce cars in China and avoid the high import duties.

If they do this I easily predict the foreign automakers will absorb their local partners who are completely dependent on sales of foreign models. More perhaps a consolidation in SOE brands is due.
