Spreadsheets are good for sorting entire records.Spreadsheets are good for smaller lists, say under 100 items.Forms, reports and queries all draw information from data in an entire database. Reports are a way to retrieve information and are usually intended for printing.Ī query is a search for information across an entire database. A form allows easy display and entry of information on a monitor. (See below for an example.)īesides tables, a relational database will also have forms. Some tables will contain only ID numbers that match items in other tables, effectively storing the relationship among those things.
Instead of entering "Seattle" or "Las Vegas" into the main table, only an ID number is needed. For example, a relational database for an address book could have a table for city names. It has only one table of information.Ī relational database has several tables for efficient storage of information because the information can be reused, needing only an ID number to represent data. A database like this is called a flat file. All the information about one person is a record. In an address book, the state is a field. An address book is an everyday database with a single table of information. A final project, a way for students to use what they’ve learned in a more creative, free-form way.A database is a collection of data on a computer organized for easy entry, searching and retrieval.Coding challenges, which give the student a chance to practice the concept and give us a way to automatically grade them and award points.
