What is the difference between distributed and replicated database?
Distributed and replicated databases have a topology of having roles : 'masters' and 'slaves' even though in a replicated database schema, the distinction becomes a little blurred. Distributed databases are normally those where information is updated on a master. The changes in the master are distributed out to a number of slave databases. The slave databases can be updated themselves but if they are, their information isn't distributed to any other database. Should the master have updated information that would contend with information in a slave, the master would take presidence. Replicated databases are normally those in which there is the capability to post updates to both 'master' through to 'slave' as well as 'slave' through to 'master'.
What is the meaning of information brokerage?

What form of data is usually presented in a table?
Tabular data is usually presented in a table format, with rows representing individual records or observations, and columns representing the attributes or variables of those records. This format allows for easy comparison and organization of the data.
What is the difference between databases and spreadsheets?
Nothing much, really. Other than the fact that a real database might contain ALOT MORE of data than a spreadsheet can. ALSO: The database might contain specific data in any field. Much more spesific that any spreadsheet can. Example: BLOB's. Binear Large Object B's. Those can contain almost anything. There are more details around this, but, anyway, a real database is something much more powerful than any spreadsheet (today anyways).
How are organisms in the domain eukarya similar to those in the domain archeae?
Both organisms in the domain Eukarya and Archaea have complex cells with membrane-bound organelles, a defined nucleus, and genetic material organized into chromosomes. However, they differ in terms of cell wall composition, membrane structure, and metabolic pathways.
What is are secondary databases in bioinformatics?
Secondary databases in bioinformatics are databases that provide curated information derived from primary sources such as research articles and other databases. They often offer organized, processed, and annotated data, making it easier for researchers to access and utilize biological information for further analysis and interpretation. Examples of secondary databases include UniProt, NCBI Gene, and KEGG.
What organize data in rows and columns?
A table. A table can be found in many applications like spreadsheets, databases and word processors. Depending on specifically what needs to be done with the data, you may choose one particular application to best fit those needs.
What is the program used for organizing numbers andor text into columns and rows?
The answer you are looking for would be a Spreadsheet, but those things can also be done with Word Processors and Databases, amongst other applications.

Why did mendeleev live some spaces in his periodic table?
During Mendeleev's time, not all of the elements had been discovered. He organized his table in such a fashion that the rows held similar properties. Also, the table was in order of Atomic Number. He knew that some elements had different properties then those next to them so he moved them down until he found it's matches.
What is the plural of that table?
The plural for that table is "those tables".
Is the periodic table organized into horizontal rows called periods and vertical columns called elements?
the horizontal rows are called periods the vertical columns are called groups A periodic table is a tabular display of the chemical elements, organized on the basis of their atomic numbers, electron configurations, and recurring chemical properties. Elements are presented in order of increasing atomic number.
What does the term sql outer join mean?
SQL is a special language for making queries to databases. An outer join is a special form of joining two tables within the database, when a SELECT query is made. In the outcome of the query you will find all selected entries from the so called "left table" (the table that was target of the select query) and only those entries from the "right table" (the one that is joined with the other) that fit a specified joining condition.
How many vowels are in table?
There are two vowels in 'table'. Those vowels are 'a' and 'e'.
Name five different ways the periodic table is organized?
By atomic number: Elements are arranged in order of increasing atomic number, which is the number of protons in the nucleus. By chemical properties: Elements in the same column (group) typically have similar chemical properties. By electron configuration: Elements are organized based on the arrangement of electrons in their atoms. By periods (rows): Elements are grouped into rows based on the number of electron shells. By blocks: Elements are classified into s-block, p-block, d-block, and f-block based on the type of subshell being filled with electrons.
