The older languages are still the standards by which modern programming languages are measured. Fortran, COBOL, Lisp, and C/C++ are all used as baselines to evaluate newer languages. Of course, the "new kids" are being used as standards more and more often. Java, Ruby, Perl, Python, and other more modern languages are being used to measure how "good" a new language is.

Eating a healthy, varied diet that is high in fruits and vegetables — including soluble fiber, vitamin D, and probiotics — is the best plan for losing weight from your waistline.

Yes, SQL is a high level language, since it allow us to get result without much going into Assembly level instructions, by using interpreter to change our statements/queries into machine level instructions!.

DML is a subset of SQL (Structured Query Language) that is used to insert, delete and revise records (or 'tuples') in a relational database. The precise definition of DML varies considerably with the database system with which it is associated.

1.take while loop in which u continue up to null in array of string.

2.once u get null pointer then take a new array of same length.

3.when u get null there ll save position no in variable i.

4.take while loop i to 0;

5.and j=0 for new array.

6.in above loop copy old array to new array in each cycle of loop.

7.j++;

8.u ll get reverse of string.

1. Field

   Name of the table field.

2. Type

   Column type such as varchar or timestamp.

3. Null

   Does the field allow null values?

4. Key

   Is this field a primary key or (a part of) and index?

5. Default

   Default field value.

6. Extra

   Additional information such as "on update CURRENT_TIMESTAMP"

If you are referring to normalization of floating point numbers, it is to maintain the most precision of the number possible. Leading zeros in floating point representation is lost precision, thus normalization removes the leading zeros by shifting left and adjusting the exponent. If the calculation was done in a hidden extended precision register (like IEEE 80-bit format) extra precision bits may be shifted in to the LSBs before restoring the result to a standard single or double precision register, reducing loss of precision.

No, SQL and MySQL are not the same. SQL (Structured Query Language) is a standardized programming language used for managing and manipulating relational databases. MySQL, on the other hand, is an open-source relational database management system (RDBMS) that uses SQL as its query language. In essence, SQL is the language, while MySQL is a specific implementation of a database system that utilizes that language.

MySQL is an open source database used by businesses to help manage their websites and other areas of their business involving high volumes of data. MySQL offers users training, certification, consulting and support.

The advantages of indexes in Oracle are that it is faster at accessing rows and is useful. The disadvantages are that the table used is small and an index must be used in order to access data.

That will depend on the relationship between the two tables. Assuming it's a simple link between the two tables, then it can be done pretty easily.

For example, take two tables, "nuts" and "bolts". Perhaps you would want to compare the price per quantity of each of those, and that value is stored in the table. You could do it this way:

...

$query = mysql_query("SELECT nuts.price AS nutprice, bolts.price as boltprice FROM nuts JOIN bolts ON nuts.quantity = bolts.quantity");

while( $data = mysql_fetch_array($query)){

do_comparison($data['nutprice'], $data['boltprice']);

}

Concurrency means use of database by many users at the same time.Concurrency control techniques (Different techniques) are used control multiple transactions interfere each other to produce wrong results.

therefore one of the main techniques used to control concurrent execution of transaction is based on the concept of locking of data item.

A lock is a variable associated with a data item in the database and describes the status of that item with respect to possible operation that can be applied to that item.

Generally there is a one lock for each data item in the database.

Depersonalization can be triggered by feelings of anxiety, stress, or overwhelming emotions, leading individuals to feel detached from themselves or their surroundings. Thoughts of inadequacy, fear of losing control, or an intense focus on self-awareness can also contribute to this sensation. Additionally, traumatic experiences or significant life changes may provoke feelings of unreality, causing a disconnect from one’s identity or environment.

An external constraint is something outside a business that stops the business achieving it's aims and objectives. For example, changing consumer's tastes.

since XLS and XLSX are proprietary formats of Microsoft products, I'm not sure there is a (free) PHP way to do so. you can export your data in CSV, which is easily opened in Microsoft Excel or OpenOffice Calc
