ይህንን ንድፍ ለመጻፍ ያነሳሳው ጽሑፉ ነበር . ከ 4 ዓመታት በፊት የታተመውን ጽሑፍም አስደሳች ሆኖ አግኝቼዋለሁ - .
ተመሳሳይ ሀሳብ አስደሳች መስሎ ነበር - "በመረጃ ቋቱ ውስጥ የንግድ ሥራ አመክንዮ መተግበር".
ወደ አእምሮዬ የመጣሁት እኔ ብቻ አልነበረም።
ደግሞም ፣ ለወደፊቱ ፣ በመጀመሪያ ፣ ለራሴ ፣ በመተግበሩ ወቅት የተነሱ አስደሳች እድገቶችን ለመጠበቅ ፈለግሁ ። በተለይም በአንፃራዊነት በቅርብ ጊዜ የስነ-ህንፃውን ለውጥ እና የንግድ አመክንዮ ወደ ኋላ ደረጃ ለማሸጋገር ስልታዊ ውሳኔ ተወስኗል። ስለዚህ የተገነባው ነገር ሁሉ በቅርቡ ለማንም የማይጠቅም እና ለማንም የማይጠቅም ይሆናል.
የተገለጹት ዘዴዎች አንድ ዓይነት ግኝት ወይም ልዩ አይደሉም። እንዴት እንደሆነ, ሁሉም ነገር ክላሲክ ነው እና ብዙ ጊዜ ተተግብሯል (ለምሳሌ ከ 20 አመታት በፊት በ Oracle ላይ ተመሳሳይ አቀራረብ ተጠቀምኩኝ) ሁሉንም ነገር በአንድ ቦታ ለመሰብሰብ ወሰንኩ. ለአንድ ሰው ጠቃሚ ከሆነ። ልምምድ እንደሚያሳየው ብዙውን ጊዜ ተመሳሳይ ሀሳብ ወደ ተለያዩ ሰዎች ብቻ ይመጣል። እና እንደ መታሰቢያነት ለራስዎ ማቆየት ጠቃሚ ነው.
እርግጥ ነው, በዚህ ዓለም ውስጥ ፍጹም የሆነ ምንም ነገር የለም, ስህተቶች እና ስህተቶች በሚያሳዝን ሁኔታ ይቻላል. ትችት እና አስተያየቶች በጥብቅ የተቀበሉ እና የሚጠበቁ ናቸው ። እና አንድ ተጨማሪ ትንሽ ዝርዝር - ልዩ የትግበራ ዝርዝሮች ተትተዋል ። አሁንም ሁሉም ነገር አሁንም በእውነተኛ የሥራ ፕሮጀክት ውስጥ ጥቅም ላይ ይውላል. ስለዚህ, ጽሑፉ የአጠቃላይ ጽንሰ-ሐሳብ ንድፍ እና መግለጫ ብቻ ነው, ምንም ተጨማሪ ነገር የለም. አጠቃላዩን ምስል ለመረዳት በቂ ዝርዝሮች እንዳሉ ተስፋ አደርጋለሁ.
አጠቃላይ ሀሳቡ “ከፋፍለህ ግዛ፣ ደብቅ እና ገዛ” የሚል ነው።
ሀሳቡ ክላሲክ ነው - ለጠረጴዛዎች የተለየ ንድፍ ፣ ለተከማቹ ተግባራት የተለየ ንድፍ።
ደንበኛው በቀጥታ የውሂብ መዳረሻ የለውም. ደንበኛው ማድረግ የሚችለው የተከማቸበትን ተግባር መጥራት እና የተቀበለውን ምላሽ ማስኬድ ነው።
