SPREADSHEETS AND DATABASES
Spreadsheet basics: A spreadsheet program helps you manage personal and business finances. They are mathematical tables which show figures in rows or columns. A cell can hold three types of data: text, numbers, and formulae.
Row Horizontal lines for data in a spreadsheet. Identified with Numbers. Column Vertical lines for data in a spreadsheet. Identified with Letters. Cell The individual intersections between rows and columns. Labeled by the Row Number and Column Letter. Active Cell The cell that is currently being edited. Marked by a think black boarder around the cell.
Uses for databases
Prepare budgets/ Maintain students grades/ Prepare financial statements/
Analyze numbers/Manage inventory/ Make forecasts
PARTS OF A DATABASE
A data base is a computerized record-keeping system. It is a system designed to store information in a way that makes it easy to locate later. A database software allows users to store, organize, and manipulate information including bot text and numerical data. Each unit of information you create is called a record and each record is made up of a collection of fields.
There are different data types:
Text: hold letters and numbers not used in calculations. Number: can only hold numbers used in calculations and reports. Memo: can store long texts. Data/Time: a date or time or combination of both.
Auto Number: assigns a number to each record. OLE Object: holds sounds and pictures. Yes/No: for alternative values like/true false, yes/no, on/off, etc.
Hyperlink: ads a link to a website. Once you have added data to a set of records, indexes must be created to help the database find specific records and classify records faster. Relational Databases: Two databases files can be related as long as they hold a piece of data in common. Extracting information from a database is known as performing a query.
GRAPHICS AND DESIGN
Types of graphics software
Computer graphics are pictures created, changed or processed by computers.
There are two categories: Bitmapped Graphics represent images as bitmaps; they are stored as pixels and can become a bit distorted when they are manipulated. The density of dots, known as the resolution and expressed in dots per inch, determine how sharp the image is. Vector Graphics represent images as mathematical formulae; so they can be changed or scaled without losing quality.
Image manipulations programs: let you edit your favorite images. Painting and drawing programs: offer facilities for freehand drawing, with a wide choice of pens and brushes, colors and patterns. Business graphics programs: let you create pie charts, bar charts, and line graphs of all kinds for slide shows and reports.
Computer aided-design (CAD): is used by engineers and architects to design everything from cars and planes to buildings and furniture. Desktop publishing (DTP): is based around a page layout program, which lets you import text from a word processor and images f
This document introduces key concepts and vocabulary related to spreadsheets. It defines a spreadsheet as a computer program that arranges data into columns and rows for calculations. A workbook contains one or more worksheets, each made up of cells located at the intersection of rows and columns. Cells can contain values, labels, or formulas beginning with an equal sign. Functions are preset formulas that perform calculations using arguments within parentheses. Other concepts covered include the formula bar, data types, autosum, charts, formatting cells, and sorting data.

The document provides a history of spreadsheets, from early counting devices like the abacus to modern spreadsheet programs like Excel. It describes how VisiCalc was the first electronic spreadsheet program in the late 1970s and was later succeeded by Lotus 1-2-3 in the 1980s. Microsoft Excel was launched in 1985 and eventually overtook Lotus as the dominant spreadsheet program due to its easier interface and transition to Windows. The document outlines key enhancements in various Excel versions over time.
A spreadsheet is a grid that organizes data into columns and rows and allows for formulas to calculate and manipulate the data. The earliest predecessors were manual accounting ledgers and the abacus, while the first electronic spreadsheet was VisiCalc in the 1970s. It popularized the concept of a value in one cell affecting others via formulas. Lotus 1-2-3 soon overtook VisiCalc's market share in the 1980s due to its power and features. Microsoft Excel now dominates the market after its 1987 debut brought the spreadsheet to Windows PCs. It has continued evolving with new features and capabilities over numerous versions.
Third normal form (3NF) requires that there are no functional dependencies of non-key attributes on something other than a candidate key.
A table is in 3NF if all of the non-primary key attributes are mutually independent
That is, there are NO transitive dependencies
Spreadsheets originated as paper ledgers organized into columns and rows. The abacus was one of the earliest counting devices. VisiCalc was the first electronic spreadsheet application, released in 1978. It organized data on a grid that allowed for formulas. Lotus 1-2-3 was the dominant spreadsheet through the 1980s, but Microsoft Excel, first released for Windows in 1987, became the most popular with its improved features and interface. Excel has continued evolving with new capabilities and versions released approximately every three years. It remains the dominant spreadsheet program today.
A database management system (DBMS) is software that allows organizations to develop databases for applications and control their creation, organization, and use. A DBMS consists of a collection of persistent data and programs to access, update, and manage that data. Early DBMS used hierarchical and network data models, while most modern DBMS are relational and use SQL. A DBMS provides data independence, security, integrity, and concurrent access. It addresses issues like data redundancy, inconsistency, and isolation that arise without a DBMS.
