מהי SQL?
SQL או בשמה המלא "Structured Query Language" (שפת שאילתות מובנית), היא שפת תכנות שמשמשת לניהול נתונים במאגרי מידע. שפה זו מאפשרת לבצע שאילתות, לעבד נתונים ולארגן אותם באופן חכם ויעיל. השפה נועדה להתמודד עם מאגרי מידע גדולים במיוחד (בניגוד לתוכנות אחרות המוכרות לנו כמו EXCEL), והינה הדרך המקובלת לניהול מאגרי מידע גדולים.
כיום, קורסים ללמידת SQL נפוצים במיוחד בשל היותם פשוטים יחסית ולא דורשים ידע מקדים רחב, וכן משום שהם יכולים להיות מקפצה להתפתחות בתחום.

קורס SQL אונליין
קורס SQL אונליין מתבצע באופן מקוון או פרונטלי, והינו דרך מעולה להתחיל את הלמידה בתחום. בהמשך לכך, קורס כזה מאפשר גמישות, לא מחייב הגעה פיזית לשיעורים, ומתאים לקשת רחבה של אנשים שאינם בעלי זמן או יכולת להתחייב לקורס פרונטלי.
קורס SQL למתחילים
מתוך שלל סוגי הקורסים בנושא שקיימים בשוק, ישנם קורסי SQL למתחילים, במסגרתם יירכשו מושגי בסיס ומיומנויות בסיסיות. התכנים של קורסי SQL למתחילים משתנים מקורס אחד לאחר, אם כי ברובם יינתנו כלים לעבודה עם השפה וכן תרגול, בכדי להגיע למצב שבסיום הקורס יוכל התלמיד לכתוב שאילתות, ליצור טבלאות ולבצע עליהן את המניפולציות השונות.
למי מתאים קורס SQL?
לימודי SQL יתאימו לאלו המעוניינים להשתלב במשק בתחום ניתוח וניהול נתונים. קורסים רבים אינם דורשים ידע מקדים בנושא כתנאי קבלה לקורס, אם כי ישנה חשיבות לאנגלית ברמה טובה וכן יכולת מתמטית. נוסף על כך, קורסים כאלו יכולים להתאים גם לבעלי מקצוע שכבר מתמצאים בשפות תכנות, אך לא בקיאים לעומק ב-SQL , ומעוניינים להרחיב את תחומי ההתמחות שלהם.
אפשרויות תעסוקה
קורס SQL פותח הזדמנויות תעסוקה רבות, ובוגריו יוכלו להשתלב בתחום ניתוח הנתונים ופיתוח – בחברות הייטק ואחרות. כמו כן, התמחות זו יכולה להוות מקפצה לתפקידי המשך בחברות, ומשמשת בסיס טוב ללמידה והתפתחות בתחומים נוספים כמו תכנות. משרות בולטות בתחום בהן יכולים להשתלב בוגרי קורס SQL הן: Database Administrator, דאטה אנליסט (Data Analyst), מדען נתונים (Data scientist) ועוד.
חשוב לציין שקורס SQL הינו קורס די בסיסי שאינו מקנה מקצוע של ממש והבטחת משרה, אך הוא נקודת פתיחה מצוינת לקראת למידה של שפות תכנות נוספות והתמקצעות בתחום.
לסיכום, קורס SQL הוא אמצעי יעיל להיכנס לעולם ניהול הנתונים ולחברות ההיי-טק. מדובר בקורס די פשוט שמאפשר צירי פיתוח שונים בתחום, לצד ביקוש גבוה בשוק למומחים בניתוח נתונים ובניהול מסדי נתונים.
