It is fun to point out though that Binary Large Objects (BLOBs) can be used to store binary files like images, audio, etc.
Would storing images in a database as a blob cause poor performance. This seems like a lot for a single entry. I would think storing a link to the image in the database would reduce the entry size.
all data on a computer must be represented in binary notation.
I am quite confused with binary notation. How is it related with chemistry?
While there are a number of styles of database the most common currently are relational.
Graph databases and other NoSQL information stores (non relational) seem to be gaining traction in filling gaps where traditional relational database struggle. MongoDB may be a good tool to include as part of future material for this course. {edit} just noticed you mention NoSQL later in the text...apologies!)
SPARQL which is the interestingly recursive acronym that stands for ‘SPARQL Protocol and RDF Query Language’.
What is the significant of this?
n the context of discussing the common ‘data types’ we are going to reference those that are used in the relational database software ‘MySQL’.
How important are the details of MySQL datatypes? Are these datatypes consistent across other relational databases?
STIX fonts
How far back in history does the STIX fonts project consider for mapping languages? For example, if one wanted to have unicodes for scientific texts from ancient egyptian era, would STIX provide a glpyh?
Then there is the much more sophisticated Visual Basic for Applications, (VBA), which sits behind Excel and is used to record the Macro’s run in Excel. VBA is much more a true programming language allowing for declaration of variables, loop structures, if-then-else conditionals and user defi
please i do not understand the practical way of using excel to check for stings and to tell if the strings is a valid InChI string or not.
Definition and Syntax for IMPORTHTML
Although we still ‘use’ ASCII today, in reality we use something called UTF-8. This is easier to say than how it is derived - Universal Coded Character Set + Transformation Format - 8-bit. Unicode (see http://unicode.org) started in 1987 as an effort to create a universal character set that would encompass characters from all languages and defined 16-bits, two bytes -> 216 -> 256 x 256 = 65536 possible characters – or code points. Today, the first 65536 characters are considered the “Basic Multilingual Plane”, and in addition there are sixteen other planes for representing characters giving a total of 1,114,112 code points. Thankfully, we don’t need to worry because if something is UTF-8 encoded it is backward compatible with the first 128 ASCII characters.
please i want know if it is possible that all computer can make use of UTF-8 and uincode
widgets
Why haven’t the major chemical database created widgets, the ones that can be downloaded and used as plug-ins on search engines like google chrome?
Although it grew out of the relational database model
Does this imply that the older relational softwares are no longer in use?
