java - Is it possible to use JDBC as an abstraction layer for RDBMS? -

-

jdbc provides api, may used connect different rdbms or similar datastores. datastores differ in implementation (e.g. sql dialects).

is possible use jdbc in such way, queries , statements work on common rdbms (e.g.: oracle, postgresql, sql server, mysql)?

that question interesting me @ 2 aspects: * common sql (insert, update, select etc.) * accessing meta data (getting information tables , columns)

i experimenting self written persistence framework , want plug jdbc datastore under it. if write jdbc datastore adapter, nice, if work on common rdbms.

thanks in advance

no not possible because serve 2 different purposes.

jdbc abstraction of dbms communication protocol, whereas sql query language.

the queries written in sql sent server using communcation protocol , results of queries returned through protocol (in dbms independent way).

there seems blurry line between communication protocol , queries jdbc api specifies calls retrieve meta data server (or result). driver free use means of transportation deems suitable. not need sql query.

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,...

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
