D.S.A

Disturbi Specifici Apprendimento

Moodle può servire nell'insegnamento online a soggetti con disturbi specifici di apprendimento, grazie alle risorse a disposizione e alla facilitazione data dall'uso del computer.


D2L

D2L stands for Desire2Learn. It is an LMS, or learning management system, similar to Moodle. It is used in K-12 and higher education settings.


DACUM

Developing a curriculum.  a developing training based on a job profile


DATABASE

database is an organized collection of data. The data are typically organized to model relevant aspects of reality in a way that supports processes requiring this information. For example, modeling the availability of rooms in hotels in a way that supports finding a hotel with vacancies.


DBMS

Database management systems (DBMSs) are specially designed applications that interact with the user, other applications, and the database itself to capture and analyze data. A general-purpose database management system (DBMS) is a software system designed to allow the definition, creation, querying, update, and administration of databases. Well-known DBMSs include MySQL, PostgreSQL, SQLite, Microsoft SQL Server, Microsoft Access, Oracle, SAP, dBASE, FoxPro, IBM DB2, LibreOffice Base and FileMaker Pro.


DIG


DISCOVERY LEARNING

The student supposedly generates and tests his own ideas, conclusions, concepts, etc., creating his own understanding of reality and giving new meanings to traditional words. In reality, he or she is prompted toward a pre-planned understanding through stories, suggestions, questions, and group dialogue


DML. Data manipulation language

data manipulation language (DML) is a family of syntax elements similar to a computer programming language used for inserting, deleting and updating data in a database. Performing read-only queries of data is sometimes also considered a component of DML.

A popular data manipulation language is that of Structured Query Language (SQL), which is used to retrieve and manipulate data in a relational database.[1] Other forms of DML are those used by IMS/DLI, CODASYL databases, such as IDMS and others.

Data manipulation language comprises the SQL data change statements,[2] which modify stored data but not the schema or database objects. Manipulation of persistent database objects, e.g., tables or stored procedures, via the SQL schema statements,[2] rather than the data stored within them, is considered to be part of a separate data definition language. In SQL these two categories are similar in their detailed syntax, data types, expressions etc., but distinct in their overall function.[2]

Data manipulation languages have their functional capability organized by the initial word in a statement, which is almost always a verb. In the case of SQL, these verbs are:

The purely read-only SELECT query statement is classed with the 'SQL-data' statements[2] and so is considered by the standard to be outside of DML. The SELECT ... INTO form is considered to be DML because it manipulates (i.e. modifies) data. In common practice though, this distinction is not made and SELECT is widely considered to be part of DML.[3]

Most SQL database implementations extend their SQL capabilities by providing imperative, i.e. procedural languages. Examples of these are Oracle's PL/SQL and DB2's SQL PL.

Data manipulation languages tend to have many different flavors and capabilities between database vendors. There have been a number of standards established for SQL by ANSI,[1]but vendors still provide their own extensions to the standard while not implementing the entire standard.

Data manipulation languages are divided into two types, procedural programming and declarative programming.

Data manipulation languages were initially only used within computer programs, but with the advent of SQL have come to be used interactively by database administrators.

DRAG AND DROP

move (a picture or highlighted text) to another part of the screen by holding down a mouse button and simultaneously moving the mouse to the desired point. Once you release the button, the object that had been dragged from a point of origin will be now in the new location.
