What is generalization in dbms?
Generalization defines a is-a-kind of relationship in which one class shares its structure and/or behavior with one or more other classes. The concept of generalization in UML is similar to inheritance in Java. It maps directly to the extends keyword. It is shown by a straight line originating from the subclass with a hollow arrowhead pointing at the nearest superclass.

This is the reason why people going to the tertiary sector because they want a job that suit them and they going to feel comfortable on the job and pay good social hours, life/work balance they choose in tertiary sector. decreasing
This is the concept of metamodeling in computer science and related disciplines. For the language patterns known as the Meta-model in Neuro-linguistic programming see Meta model (NLP).
Most general, metamodeling or meta-modeling is the analysis, construction and development of the frames, rules, constraints, models and theories applicable and useful for the modeling in a predefined class of problems. This concept definition is composed with the notions of the terms meta- and modeling.

The term digital signal is used to refer to more than one concept. It can refer to discrete-time signals that are digitized, or to the waveform signals in a digital system.
Digital signals are digital representations of discrete-time signals, which are often derived from analog signals.
As a simple example digital signals are like number of people. we can count them as 1, 2, 3, 4,.....etc . We cannot count as 3.5 or 6.75 or ...etc. But analog signals are like their body temperature. It can be 32 or 34.7 or 36.876 etc. They changes in a infinite range. Not digitized as digital signals.

What is difference between manifest and meta data?
menifest also reffered to as assembly metadata(data about data),contains all information related to assembly like identity section,version number,strong name (optional),culture.so menifest contains information related to the identification assembly or it is a part of assembly where assembly is self describing.
metadata is the information that enables components to be self describing.it is used to describe which class is used,function,methods,fields ....So it is the data about data.
How do you represent Structured Query Language data types as fields?
When you create a table, you define the field names and the type of data they will contain. As an example (for Microsoft SQL Server)... CREATE TABLE SampleTable ( SampleTableID AS INT, SampleTableFirstName AS VARCHAR(50), SampleTableLastName AS VARCHAR(50), SampleTableAge AS DOUBLE ) In the above example, the field names all are prefixed with SampleTable (just for illustration) and the datatypes all follow the AS keyword.

What is meant by a thread in java programming language?
A thread and a process are same but a minor difference is there.
Process executes a program completely without splitting whereas a thread splits a program into smaller tasks and then execute them separately.And then combine the final result.
that is why a process is often called as Heavy weight and a thread is called as light weight.
Hi,
The abbrevation of basis is Business Application Software Integrated solution.
Basis is a function/module (like Finance, Materials, Quality, Production etc)in SAP. Basis is the Administoring programs which administer the SAP Application. Basis Administrator administers the SAP application using the tools or transactions available under Basis component. Normal functions like creating user, assigning access rights, backup, restore, check the performance are some of the transaction available under Basis component in SAP. Earlier upto SAP version 4.6 there is only basis version available and all other functional component where add ons. From sap version 4.7 Basis is integrated with all other functional module. Hope this helps

Is SQL an open source software or open access software?
SQL is not software in the sense that you can run it as a stand-alone program. SQL stands for Structured Query Language and is that a language for querying relational databases. It was originally developed at IBM and became the de facto standard relational database query language in the 1980s.
In order to execute (run) SQL queries against a database, you need an implementation that can interpret the SQL statement and return the data as specified from your data store. Also, Open Access as a concept does not apply to software. See related links for details.
√ this is the symbol for square root. So if you take a number, say n, then √n means the square root of n. This of course means that is √n=m, where m is some number no necessarily different from n, then n2 =m
For example √36=6
but √1=1
What are example files of data encoding?
Not to be flippant, but every file is an example of data encoding. Before data can be stored in computer memory or in a disk file, it first has to be digitally encoded in binary. The binary encodings can then be further encoded using encryption or compression.
What is data loader in salesforce?
A data loader is software that allows for the automated import, export, and storage of Salesforce data in large volumes.
A data loader is used to import, export, and delete an unlimited amount of data for your business in a quick and secure manner.
A Salesforce data loader is a universal tool used for bulk importing and exporting of data. It provides a user-friendly UI or command line access.
A data loader can input, update, and completely delete large amounts of Salesforce records.
What is centralized database design?
Centralized design is one of the two major methods of designing a networked database, the other being distributed design. In a centralized design, all the database table schema and the data reside in one place where all of the users access it (i.e., central to the users.) Conversely, a distributed design replicates the schema in multiple places and segments the data amongst the multiple sets of tables. Each group of users accesses a particular distributed set of tables with the data relevant to their group. This improves data security and retrieval time for the users at the cost of increased complexity of database maintenance and backup.
In programming, a parent node is any node that holds some reference to a child node. The child node may itself be a parent node.
A classic example of parent/child node usage is the binary tree, where every node in the tree may hold a reference to up to 2 children. Nodes that have no children are known as leaf nodes.
How does the government use demographic data?
It depends on the government's priorities, but demographic data can be used to allocate government spending. A couple of examples:
more schools for area with high proportion of young couples,
more healthcare facilities for areas with older people.
What data type automatically increases each time a new record is entered?
There is no data type that automatically increases each time a new record is entered. You are probably thinking of a linked list, but that is not a data type, it is a container and it must be manually programmed to ensure correct behaviour. However, C does not provide object-oriented encapsulation so correct behaviour cannot be guaranteed. In C++, all containers are implemented as encapsulated objects, thus correct behaviour can be assured and the container can shrink and grow automatically.
