Worksheet, Workbook, and Spreadsheet BasicsWorksheet Concept: A worksheet is a single page within an Excel workbook where data is stored and manipulated.Workbook Fundamentals: A workbook is a collection of worksheets, saved in a single file.Spreadsheet Basics: A spreadsheet is the digital equivalent of a paper ledger, containing data organized in rows and columns.Managing Worksheets and CellsAdding, Renaming, and Deleting Worksheets: Users can create, rename, and delete worksheets within a workbook.Inserting/Deleting Rows and Columns: Insert or delete entire rows, columns, or cells.Cell Size Adjustment: Modify cell dimensions, including row height and column width.Cell Address and Formula Bar: Cells are identified by a combination of letters (columns) and numbers (rows) and can contain data or formulas.Cut, Copy, Paste: Basic operations for moving data within the sheet, including options like "Paste Special" for conditional pasting.Format Painter: Copies formatting from one cell or area to another.Formatting and EnhancementsCell Formatting: Customize cell appearance, including number formats, font styles, and colors.Inserting Media: Add pictures, shapes, and textboxes to a worksheet.Page Layout: Set headers, footers, and other print-related settings.File Management: Save, save as (different format like CSV), spell check, and sheet protection options.Split, Hide, Freeze Panes: Useful for managing large datasets by freezing certain areas, hiding content, or splitting the screen.Charts, Data, and FunctionsChart Types: Create 2D and 3D charts such as columns, lines, pies, bars, and scatter plots.Basic Functions: Functions like Power, Sqrt, Abs, Floor, Ceiling, Int, Trunc, Round, Sum, Average, Count, Max, Min, Sumif, Pmt, Stddev.Logical Functions: IF, AND, OR, NOT, TRUE, FALSE for conditional logic.Date and Time Functions: Date, day, time, now, hour, minute, second, month, Days360, weekday.Data Management: Sort, filter, and apply conditional formatting or cell validation.Advanced Options: Subtotals, text-to-columns, and duplicate removal.Database ConceptsDBMS Introduction: A Database Management System (DBMS) is software for storing and retrieving users' data efficiently.Database Characteristics: Includes data independence, minimized redundancy, and optimized data access.Data Independence: Logical and physical separation between data and applications.DBA Role: Database Administrator manages the database's performance, security, and maintenance.Database Architecture and ModelsDatabase Architecture: 1-tier (standalone), 2-tier (client-server), 3-tier (multi-tier).Database Models: Hierarchical, Network, E/R (Entity-Relationship), and Relational models.Schema and Instance: Schema is the design, while the instance is the actual data.E/R Diagram Elements: Entities, relationships, attributes, and mapping cardinalities (1:1, 1, M:1, M).Keys and RelationshipsTypes of Keys: Super key, candidate key, primary key, composite key, unique key, and foreign key.Normalization: Organizing data to reduce redundancy and improve data integrity.Anomalies: Insert, update, delete.Functional Dependency: Relationships between columns.Normal Forms: 1NF, 2NF, 3NF, BCNF.SQL FundamentalsSQL Overview: Structured Query Language (SQL) is used to manage and manipulate relational databases.SQL Datatypes: Different data types (e.g., INT, VARCHAR, DATE).DDL (Data Definition Language): Commands like Create, Drop, Truncate, Rename, Alter for managing table structure.DML (Data Manipulation Language): Insert, Update, Delete to manage data.DQL (Data Query Language): SELECT to retrieve data.Querying and ConstraintsConstraints: NOT NULL, CHECK, DEFAULT, UNIQUE, primary key, foreign key, and cascading deletes.WHERE Clause and Operators: Filtering data with operators like IN, BETWEEN, LIKE, AND, OR.Ordering and Aggregation: ORDER BY, DISTINCT, GROUP BY, HAVING, and aggregate functions like AVG, MAX, MIN, SUM, COUNT.Views: Virtual tables created from SQL queries for simplified data access.
