Answer all questions in this section
A database is organized in a structured manner to efficiently store, manage, and retrieve data. The organization of a database typically involves the following components:
- Tables, The fundamental structure in a database, where data is stored in rows and columns
- Records (Rows), Each row in a table represents a single record, containing a set of related data
- Fields (Columns), Columns in a table represent the attributes or properties of the data stored. Each field holds a specific type of data.
- Primary Keys, Unique identifiers for records in a table, ensuring that each record can be distinctly identified.
- Relationships, Connections between tables that define how data in one table is related to data in another. This is essential for maintaining data integrity.
- Indexes, Special lookup tables that the database search engine can use to speed up data retrieval.
- Views, Virtual tables created by querying data from one or more tables, which provide a specific representation of the data.
- Customer Relationship Management (CRM), Managing customer data, interactions, and relationships to improve business relationships and customer satisfaction.
- Enterprise Resource Planning (ERP), Integrating and managing core business processes like finance, HR, and supply chain within a centralized database.
- Data Warehousing, Storing large volumes of historical data for analysis and reporting purposes, which aids in decision-making and business intelligence.
- Online Transaction Processing (OLTP), Supporting day-to-day transactional systems like banking, e-commerce, and retail operations, where high volumes of data are processed quickly and accurately.
- A field is a single unit of data within a record in a table. It represents an attribute or property of the data, such as a name, date, or price. For example, in a table storing information about books, a field could be "Title" or "Author".
- A character is the smallest unit of data that can be stored in a database. It includes letters, numbers, and symbols. For example, the letter "A", the number "7", and the symbol "&" are all individual characters.
- A file in the context of a database is a collection of related records or data stored together. It can be considered a table in a relational database or a document in a document-oriented database. For example, a customer file might contain records of all customers and their related information.
- Descriptive Names (Field names should clearly describe the data they store. For example, use “CustomerName” instead of “CN”.)
- No Spaces (Avoid spaces in field names to ensure compatibility across different database systems. Use underscores (_) or camel case. For example, “First_Name” or “FirstName”.)
- Consistency (Maintain consistent naming conventions throughout the database to improve readability and maintainability. For example, use either camelCase or snake_case consistently.)
- Avoid Reserved Words (Do not use SQL reserved words or database system-specific keywords as field names to prevent conflicts. For example, avoid using names like “Select” or “Date”.)
A data type specifies the kind of data that can be stored in a field. It defines the type of value, such as integer, text, date, or boolean, that the field can hold. Data types help ensure data integrity by restricting the type of data that can be entered.
- Uniqueness, Ensures each record in a table is uniquely identifiable, preventing duplicate records.
- Data Integrity, Maintains data integrity by uniquely identifying each record and establishing clear relationships between tables.
- Efficient Indexing, Improves database performance by providing a unique identifier for fast data retrieval and indexing.
The three (3) merits are
- Data Integrity and Consistency (Ensures data is accurate and consistent across the database through constraints and rules.)
- Data Security (Provides robust security features to protect sensitive data from unauthorized access.)
- Efficient Data Management Facilitates efficient storage, retrieval, and management of large volumes of data.
- Cost (Implementation and maintenance of a DBMS can be expensive, including hardware, software, and personnel costs.)
- Complexity (Requires specialized knowledge to design, implement, and manage databases, which can be complex and resource-intensive.)
- Performance Overhead (Can introduce performance overhead due to the complexity of managing transactions, security, and data integrity.)
Visible Files are accessible and viewable by users within the file system. These files can be opened, modified, and managed directly by users. Examples include tables, forms, and reports in a database.
Invisible Files are hidden from the user and usually contain system data or metadata required for the database's internal operations. They are not meant to be accessed or modified directly by users. Examples include system logs, temporary files, and configuration files.
A form in the context of a database is an interface that allows users to enter, modify, and view data in a structured and user-friendly way. Forms facilitate data input and editing by providing an easy-to-use interface that maps to the underlying database tables.
- Open the database in which you want to create the form.
- Choose the table for which you want to create the form.
- Use the form creation tool in the database management software to create a new form. For example, in MS Access, you can use the “Form Wizard” or “Form Design” tool.
- Customize the form layout by arranging fields, adding labels, and designing the interface.
- Save the form with a meaningful name.
- Enter some sample data to test the form and ensure it functions as expected.
- Select Query
- Action Query
- Parameter Query
- Crosstab Query
- SQL Query
