CSV is a delimited text file that uses a comma to separate values (many implementations of CSV import/export tools allow other separators to be used; for example, the use of a "Sep=^" row as the first row in the *.csv file will cause Excel to open the file expecting caret "^" to be the separator instead of comma ","). Simple CSV implementations ...
The two most common representations are column-oriented (columnar format) and row-oriented (row format). [ 1 ] [ 2 ] The choice of data orientation is a trade-off and an architectural decision in databases , query engines, and numerical simulations. [ 1 ]
Range sum queries may be answered in constant time and linear space by pre-computing an array p of same length as the input such that for every index i, the element p i is the sum of the first i elements of a. Any query may then be computed as follows: (,) =.
Multiple header rows in a sortable table should have the static-row-header class added to all header rows except the first one so that they are not numbered when JavaScript is disabled. It is also needed on rows that use the sorttop or sortbottom class, described at #Disable number on specific rows .

The Field Names, Header Fields and Repository of Provisional Registrations are maintained by the IANA. Additional field names and permissible values may be defined by each application. Header field names are case-insensitive. [4] This is in contrast to HTTP method names (GET, POST, etc.), which are case-sensitive. [5]
name: Name of the line in the BED file No 5: score: Score between 0 and 1000 No 6: strand: DNA strand orientation (positive ["+"] or negative ["-"] or "." if no strand) No 7: thickStart: Starting coordinate from which the annotation is displayed in a thicker way on a graphical representation (e.g.: the start codon of a gene) No 8: thickEnd
This means that there is a header which describes the layout of the rest of the file, in particular the data arrays, as well as arbitrary file metadata in the form of name/value attributes. The format is platform independent, with issues such as endianness being addressed in the software libraries. The data are stored in a fashion that allows ...
