Deletion anomaly Discovery phase Entity integrity Field (or Column) First normal form (1NF) Flat file database Form Functional dependency Hyperlink data type Insertion anomaly Junction table Lookup Wizard data type Macro Many-to-many Definition A query that performs an action on the table on which it is based. A field whose sole purpose is to create a primary key An automatically generated number that produces unique values for each record A table on which the query is based and is displayed in a datasheet A field that appears in two or more tables and contains identical data to relate the tables. A query that performs calculations on the values in a field and displays the results in a datasheet. Monetary amounts When multiple records are stored for the same entity Data, which is unnecessarily duplicated. Determines how to store the data in the field Software that provides a system by which you can manage data. A table, with fields displayed in columns and records displayed in rows. Dates or date and time combinations A problem that occurs when a user deletes data from a database and unintentionally deletes the only occurrence of that data in the database Includes gathering all existing data, researching missing and incomplete data, and talking with users about their data output needs. Subsequent steps in the process include putting data into groups, called tables; identifying unique values for each record in those tables; and designing the database to produce the desired output. A guarantee that there are no duplicate records in a table, that each record is unique, and that no primary key field contains null values A single characteristic of an entity When a table does not contain any repeating groups A simple database that contains a single table of information An object that is used to view, add, delete, update, and print records in the database. A form can be based on a table or a query. A column in a table is considered functionally dependent on another column if each value in the second column is associated with exactly one value in the first column Text that contains a hyperlink to an Internet or file location A problem that occurs when a user cannot add data to a database unless it is preceded by the entry of other data. An intermediary table that contains the primary keys from two tables that are to be joined A field that lets you look up data in another table or in a list of values created for the field A set of instructions that you specify to automate certain database tasks. A macro might contain instructions to open a specific form or query in the database when you click a command button on a form. A relationship in which each record in the first table matches many 1-1 Succeeding in Business with Microsoft Office Access 2003 relationship (abbreviated as M:N) Memo data type Module Natural key Normalization Null value Number data type OLE object One-to-many relationship (abbreviated as 1:M), One-to-one relationship (abbreviated as 1:1 Orphaned records Page, also called a data access page Partial dependency Primary key (or a composite key) Primary table Query Referential integrity Related table Relational database Repeating group Second normal form (2NF), Surrogate key - Text data type Third normal form (3NF), Transitive dependency Visual Basic for Applications (VBA), Yes/No data type Chapter 1 records in the second table and each record in the second table matches many records in the first table. Long passages of data containing text and alphanumeric characters An object that contains instructions to automate a database task. Modules are written in VBA A primary key that details an obvious and innate trait of a record A process used to ensure a good database design A field that does not contain a value, either because that value is unknown or inapplicable Numbers that are used in calculations Linked or embedded objects that are created in another program A relationship in which one record in the first table matches zero, one, or many records in the related table. A relationship in which one table matches exactly one record in the related table. When there is no longer a match between the primary key in the primary table and the foreign keys in the related table A Web page that lets you view and interact with data stored in an Access database. A condition that occurs when a field is dependent on only part of the primary key When a primary key uses two or more fields to create unique records in a table The “one” side of the 1:M relationship A question that you ask about the data stored in a database, The rule that if the foreign key in one table matches the primary key in a second table, the values in the foreign key must match the values in the primary key. The “many” side of the relationship A database which contains related tables through fields that contain identical data When a field contains more than one value A table that is in 1NF and does not contain any partial dependencies on the composite primary key A computer-generated primary key that is usually invisible to users A form that might be displayed when you open a database and provides a controlled method for users to open the objects in a database. Text or alphanumeric combinations of data and numbers that are not used in calculations A table that is in 2NF and the only determinants it contains are candidate keys. A condition that occurs between two nonkey fields that are both dependent on a third field; tables in 3NF should not have transitive dependencies. The programming language for Microsoft Office programs, including Access. A field value that is limited to yes or no, on or off, and true or false values 1-2
