Answer:

data manipulation language

Explanation:

Data manipulation language (DML) is a family of similar syntactic elements used to select, insert, delete and update data in a database. Performing data read-only queries is sometimes considered a component of the DML.

The best known data manipulation language is the SQL (Structured Query Language) that is used to receive and manipulate data in a relational database. Other forms of DML are those used by IMS / DLI, CODASYL databases, such as IDMS and others.

Data manipulation languages comprise only the SQL statements that allow you to modify data, but not modify the schema or objects of the database. The manipulation using SQL statements of persistent database objects such as tables or stored procedures, is considered Data definition language and not Data manipulation language. In SQL these two categories are similar in their syntax, data types, expressions, etc., but they are different in their general function.

during the 1980's, the price of one share of Johnson and Johnson stock rose from $17 1/4 to $56 1/8. how much money would you ha

Andre45 [30]

Given:

Price of one share in 1980 = $ $17\dfrac14$

Price of one share in 1989 = $ $56\dfrac18$ .

To find:

How much money would you have made if you bought 100 shares of Johnson & Johnson stock in 1980 and sold it in 1989?

Explanation:

Using the given information,

Change in the value of each share = $56\dfrac18-17\dfrac14$

= $\dfrac{448+1}{8}-\dfrac\dfrac{68+1}{4}$

= $\dfrac{449}{8}-\dfrac\dfrac{69}{4}$

= $\dfrac{449-138}{8}$

= $\dfrac{311}{8}$

Value of one share increased by $ $\dfrac{311}{8}$ .

Value of 100 shares increased by = $100\times \dfrac{311}{8}$

= $\dfrac{31100}{8}$

= $\dfrac{7775}{2}$

= $3887.5$

Therefore, you would have made $3887.5 if you bought 100 shares of Johnson & Johnson stock in 1980 and sold it in 1989.
