Study Notes

Access Unit B Key Concepts

AND Criteria: Used in a query design grid where all criteria in the same row must be true for records to appear in the datasheet.
Criteria: Rules or conditions that determine which records are visible in a datasheet, form, or query; essential for filtering data.
Criteria Syntax: Specific formatting rules for entering criteria; text requires quotation marks, while date criteria must be enclosed in pound signs.
Field Lists: Displays available fields in a table or query; opens as a pane in Access, providing an overview of database tables and their fields.
Field Selector: A button or gray bar in Table Design View indicating the currently selected field, aiding in field management.
Filter By Form: Enables filtering of data using multiple criteria simultaneously, enhancing specificity in data retrieval.
Filter By Selection: Focuses on filtering records to find exact matches based on selected criteria.
Filtering: Temporarily shows records that meet specific criteria, allowing for simpler data analysis.
Is Not Null: Criteria to find records where a field contains any entry, ensuring data availability in searches.
Is Null: Criteria to identify records with no entries in a field, useful for identifying incomplete data.
Join Line: Visual representation of relationships between fields in two related tables; also known as the link line.
Like Operator: Used in queries to find field values that match specified patterns, facilitating flexible searching.
Logical View: Refers to the datasheet display of a query, representing a selection of data rather than duplicating original data.
OR Criteria: Positioned on different rows in the query design grid, allowing records to appear if any single row criteria are met.
Query: An Access object providing a structured view of data; offers a streamlined approach to displaying fields/records from tables based on user questions.
Query Design Grid: The bottom section of the Query Design View where fields, sort order, and limiting criteria are set for the query.
Query Design View: The interface for developing queries, specifying fields and criteria to determine displayed records.
Save As Command: Command under the FILE tab used to save an open file with a new name or location, applicable to entire databases or individual objects.
Simple Query Wizard: A user-friendly tool in Access guiding users through creating a new query by providing relevant information.
SQL (Structured Query Language): A widely used language for requesting information from relational database systems, essential for data manipulation and retrieval.
Wildcard: Special characters that enhance query flexibility; an asterisk (*) represents multiple characters, while a question mark (?) represents a single character.
