Database Programming
Databases are collections of tables that maintain and display information, often collaboratively; this information can be used for interaction with an application or gaining general knowledge. Questions about database engines and modifying or using them belong in this category.

What is Standards and certification in software engineering?
Standards in computer science engineering include ISO and Six Sigma. Certifications in these fields include C++. Microsoft Certified Systems Engineer, J+ and COBOL.
Advantages of procedure oriented programming?
The ability to reuse the same code at different places in the program with out coping it.
Database is vulnerable because it collects, maintains, and disseminates information. These data essentially include exploitability and potential impact. Example of this is the Open Source Vulnerability Database.
What is the foreign key constraint?
foreign key constraint defines a column or combinations of columns whose values match the primary key of another table.
Functions of database management systems?
Applications of interfaces to the DBMS are created, allowing users to manage and gain access to data within the database. Connolly & Begg (2001, pp 4) state 'a database application is simply a program that interacts with the database at some point in its execution'.
Interfaces of a DBMS provides functionality with the ability to add, delete, update and retrieve data, process data to complete tasks, produce reports and manage data.

Embedded SQL is a method of combining the computing power of a programming language and the database manipulation capabilities of SQL. Embedded SQL statements are SQL statements written inline with the program source code of the host language. The embedded SQL statements are parsed by an embedded SQL preprocessor and replaced by host-language calls to a code library. The output from the preprocessor is then compiled by the host compiler. This allows programmers to embed SQL statements in programs written in any number of languages such as: C/C++, COBOL and Fortran.
The ANSI SQL standards committee defined the embedded SQL standard in two steps: a formalism called Module Languagewas defined, then the embedded SQL standard was derived from Module Language.[1] The SQL standard defines embedding of SQL as embedded SQL and the language in which SQL queries are embedded is referred to as the host language. A popular host language is C. The mixed C and embedded SQL is called Pro*C in Oracle and Sybase database management systems. In the PostgreSQL database management system this precompiler is called ECPG. Other embedded SQL precompilers are Pro*Ada, Pro*COBOL, Pro*FORTRAN, Pro*Pascal, and Pro*PL/I.
well it's a measure of space in a technological database (i.e. a harddrive) some relations are 1024MB = 1GB 1MB = 1024KB 1MB = 1024000 bytes How much space a virus that slows down your computer takes = all your MB

What is the difference between sql and Microsoft Excel?
SQL means Structured Query Language. It is a programming language which is mainly used for maintaining databases. Excel is one of the application developed by Microsoft to do calculations, graphs using spreadsheets.
Discuss the function of Database Management System?
- allows users to manage and gain access to data within the database.
- aids with features of functionality with the ability to add, delete, update and retrieve data at any time,
- process data to complete tasks,
- produce reports and manage data.
