Hi, I am Jetelina that is your helper to create database tables and WebAPIs that are related with the created database.
	The databases that I can manage so far are PostgreSql, MySql, Redis and MongoDB.
	You should visit my website jetelina.org if you wanna know my overview.Type 'go jetelina.org'.
	This guidance only introduces 'HOW TO USE ME' to you.
	    The first of all, you can move to the 'X' page with typing 'page X', e.g. 'page 2', but 'go to page 2 please' is more friendly to me. :)
	'next' or 'previous' and 'go to the first/head' or 'go to the last/end' are available as well.
	And to out of this guidance, give me 'thx', 'thank you', etc.
	You may wonder about my reactions sometimes due to your typo. Check what did you type with 'what did i type?' or 'what did i say to you?',
	also you can see them with puting your mouse cursor on the tiny font between my words and your input field in our chatbox.

	Oops, in the case of this is your first access to me, this is the login method.
		step 1. type 'hi' into my chatbox, we always start with a greeting, 'hello' is good as well
		step 2. chat with me till i ask your name
		step 3. type your 'name' that is registered as your account when i finally ask to you
				

			IMPORTANT: IF YOU ARE THE FIRST, 'it is me' is the acccount for initialization me. 
				

		step 4. then we start to work something together
		step 5. type 'exit','logout','bye'...etc to logout from me

	These are the basic operations from starting to use a database to create a DBI then publish it,
	    in page 2
		   2-1. how to use databases
		   2-2. how to create tables by uploading a csv file
	    in page 3
		   3-1. how to manage a created table
		   3-2. how to create DBI from a create table and publish it as a WebAPI
	    in page 4
		   4-1. can i check and test the DBI before publishing?
		   4-2. how to switch databases, e.g. PostgreSQL to Redis
		   4-3. how to delete the created DBIs/WebAPIs
	Next, these are the intermediate operations about getting error reasons in your WebAPIs,
	    in page 5
		   5-1. when and where i will see the error happened?
		   5-2. can i fix the error?
	Ok, these are the advanced operations, but do not need any special account,

		   6-1. how to know each WebAPIs daily access numbers
		   6-2. how to know each databases total access numbers
		   6-3. how to know each WebAPIs execution speed 
	And these are another advanced operations you need privilege roll.To know you have it or not, type 'who am i' after logging to me,
	you can operate the belows if you have 'admin' roll.

	                                                                              OK, type the page number what you wanna to see,'page x','next','previous'.... or 'thank you' to exit
				

	You and I can handle PostgreSQL/MySQL/Redis/MongoDB. You type your database whichever, e.g 'use postgresql', then follow me.
	After connecting to the database, the icon is highlighted. This is the signal of current working database.
				

	Every table in databases, in case NonSQLs are key or document, are created by uploading a csv file to me.
	You type 'file open','upload file'...etc, then the file box is open, select your file, then follow me. 
	A csv file has some rules,
			(1) the file name is to be the table name
			        e.g   ftest.csv  →  'ftest' table   
			(2) inside the file: csv format with headers
			        e.g   
			           name,sex,age,ave   ← headers(be a table column name)
		               AAA1,m,10,0.1      ← data
		               BBB2,f,20,0.2
			(3) an unique id is put on each row data automatically
			(4) the column data type is decided automatically by me
			        e.g
						name:AAA1 is string	→ 'name' column is to be varchar
						age :10 is integer	→ 'age' column is to be integer
						ave :0.1 is real	→ 'ave' column is to be double

	thus, uploading a ftest.csv creates 
		table name: ftest
		table coluns are:
			| id | name |  sex  |  age  |  ave  |
			|  1 | AAA1 |   m    |  10   |  0.1  |
			|  2 | BBB2 |    f     |  20   |  0.2  |

				

	ATTENTION:
	duplicated uploading is inserting them to the exist table, i mean,
			| id | name |  sex  |  age  |  ave  |
			|  1 | AAA1 |   m    |  10   |  0.1  |
			|  2 | BBB2 |    f     |  20   |  0.2  |
			|  3 | AAA1 |   m    |  10   |  0.1  |     ← inserted
			|  4 | BBB2 |    f     |  20   |  0.2  |   ← inserted

	the headers (name,sex..) are to be column name, thus you can not use '-' and so on, these are not 
	allowed to use in there depend on a database. In fact, the column name will be named with the file name + header name,
	for example, ftest_name, ftest_sex... in above example. Because I wish every columns are uniquness.
				

	The created tables are shown in the left panel on me. 
		(1) 'select xxxx' or 'open xxxx' is for opening the xxxx table, then its columns are displayed in the center panel
		(2) 'drop table xxxx' is for dropping 'xxxx' table, the associated DBIs/WebAPIs are also deleted synchronously
				

	CAUTION: this table droppping is parmanent deleting, i mean it is as same as 'drop table xxxx' in SQL
				 

	Some DBIs/WebAPIs are created automatically by creating a table, I mean when you upload a csv file to me.
	These are displayed in the right side panel. They have a meaning full name,
											
		- created automatically
			'ji': data insert api. I create it automatically by uploading your csv file.
			'ju': data update api. Same above.
			'jd': data delete api. Again.
					
		- you will create
			'js': data select api. 
					
	Try to type its name, e.g 'select ji12' or simply 'select 12', then you see 'IN','OUT' and a sql sentence, in case RDBMS, below. 
	'IN' and 'OUT' are the WebAPI's I/F, and the sql sentence is the execution in fact. 
					
	To create 'js' API, 
		(1) open the table with 3-1(1)
		(2) type the column name that is displayed in the center panel to select it
		(3) to cancel the selected 'xxxx' column, type 'cancel xxxx' or 'reject xxxx', or 'cancel all' is for canceling all

	(1)-(3) are enough if your new API stands on a very simple SQL. Go to (5) or (6).
	But below (4) is for setting a subquery if you need more complicated request.

		(4) type 'go subquery' or shortly 'go sub' to describe a subquery sentence.
		    the subquery panel arise then write your subquery phrase in there, e.g 'where ftest.ftest.age < 30'

	I have very kindly a test procedure for your new API, this process is optional.

		(5) type 'test api' or 'test sql'...., I execute the sql that is defined by selected items and the subquery.
		    the result is displayed as json form in a new panel.
		(6) to create api, simply type 'create api', then follow me. 
				

	ATTENTION:
	In the case of you set the subquery, its variable parameter must enclosed with '{}', and the rule is following the database 
	I mean, if you tested the api with 'where ftest.ftest_age < 30', and you wanna '30' to be a variable parameter, you must change it {age},
			where ftest.ftest_age < 30    →    where ftest.ftest_age < {age}     ← CAUTION: {age} because 'age' is integer
		in the case of character, for example 'name'
			where ftest.ftest_name = 'AAA' →  where ftest.ftest_name = '{name}'     ← CAUTION: '{name}' because 'name' is character
				

	Yes, you can do it. To test the created API,
		(1) select API's name by typing ..... as same as above 1
		(2) type 'test api' or 'check api' and so on
		(3) I ask you the input values due to 'IN' I/F, you set the values in out chatbox, then the inputs are replaced in 'IN', look at them
		(4) I say to you "..type 'boom'..." or something after all params are set, then you type it
		(5) the result is displayed in 'OUT' I/F, confirm it
		(6) finally you say 'thank you', 'great'... to me, OK? :)
				

	Toled this in 2-1(1), but again. Type 'use xxxx' or 'switch to xxxx'.... to change to 'xxxx' database.
	    e.g  'use mysql'
				

	You can only delete 'js' APIs, because it is created by you. Others, 'ji', 'ju','jd' are under my control. These APIs can be 
	deleted by dropping the related table.
		(1)	Type 'delete api js100' or 'reject api js100' ....., to delete 'js100' api. Multi deleting is 'delete api js100 js200'.
		(2) The selected apis are changed its bgcolor, then follow me.			
				

	I know sometimes happen something error, e.g creating tables/apis/api-test and so on.
	The error messages are displayed if they were, and you can ask me.
	Type 'open error', 'what happend' or 'detail please'....., when something happen but do not display it.
	I inform you the reason as much as i possible.
				

	Depend on the reason. The most of the cases are cause of your APIs manipurations as I know.
	You can resolve them by yourself due to my suggestions. Others.... may you can ask it to my web site. Good luck.
				

	I total up your DBIs/WebAPIs access numbers in daily.
		(1) type 'show api access numbers' to open the list
		(2) then you can move the page with typing 
			'next' to next page
			'previous' is for backing,
			'last' or 'end' jump to the last page
			'head' or 'first' back to the top page
		(3)	type 'search xxxx', e.g 'search js100', to search an api 'xxxx' 
		(4) type 'search clear' back to the list.
				

	You may wanna know the share of your databases, i mean for example MySQL is used 60%, Redis is used 40%.
		(1) type 'show db access' to open the rate as pie chart. This chart is yearly data.				
				

	You know I am watching your api execution peed, mean/max/min in daily.

		(1) type 'show api speed of xxxx' to figure out api 'xxxx' data, e.g 'show api speed of js4'.
	
	Basically 'flat' lines are ideal in each data. But sometimes happen the execution speed deprecating.

		(1a) type 'any alerts?' or 'any reports?' to see my REPORT in the execution speed problems. 

	I report you if the mean speed is out of 1σ, 2σ and 3σ in standard deviation. 
	That's all what I can do. I relay on you to fix the problems.
	And if you do not care about them, 

		(1b) type 'do not worry', 'never mind'... to make me feel safe.
				

You need the privilege roll to manage these operations.To know you have it or not, type 'who am i' or 'show my profile' after logging to me, you can operate the belows if you have 'admin' roll.

	To create a new user, it is incredible simple.
		(1) type 'invite new user', 'add new user' or 'add user' .... something like that
		(2) then i ask you the user name, then follow me
	That's all. The user roll what it can on me is decided by your 'generation' and the user's experience.
				

	IMPORTANT: What is 'generation'?
			   The 'generation' is an unchangeable primitive number with an account, please refer my web site about the detail, 
			   but let's say it simply as below.
			   
			    'generation 0' is 
			                     accounts who were created in installing me on here,
			                     available the functions: create&delete table/api, create a new user, change my configuration.
			    'generation 0<' are 
			                     accounts who were registered by 'generation 0', and 'generation 2' is ... you know, 
			                     be able to do them after gaining a lot of experiences.

			   Say again, 'generation 0' accounts are able to manage all functions, but 'generation 1-x' will be possible them 
			   after gaining much of experiences on me.
			   Other word, 'generation 1-x' accounts need to be trusted by me.
				

	I bet you are an expert in databases if you wanted to try this.
	The typical values of parameters on each databases are already set in me and try to connect to databases with these parameters 
	due to your order as 'i wanna use xxxx', 'switch to xxxx'..., e.g 'i wanna use postgresql'.
	I give 'success' message to you if the connection had been built, but in the case of unconnectable, I will show you the error message.
	Then you can fix the error with your own values,
		(1) in success: happy messages to you
		(2) in fail: show the reason why 
		(3) change the parameter with typing 
		(4) try to connect again with typing
				

	CAUTION: I do not expect to change any parameters in runing, these were set in very first time to use it. Therefore I keep staying in
	         bothersome changing it in Ver.3. You should refer how to do it in my website. 
				

	You may wanna change my original parameters to your favorits.
	There are two way to make it,
		(1) rewrite my configuration file by your hand
		(2) change it in the chatbox

	Naturally (1) is available because I am a program, but as you know demending restart the server if you changed me.
	The way of (2) is recommendable because the changing will be seamless, i mean you do not need to restart me at all, but this operation
	has	a little bit risks on you. Thus I strong recomend you to visit to my website and refer how to do it.
