Text or combinations of text and numbers stored. OLE objects can store audio, video, other Binary Large Objects. Multiple files can be attached per record. It only stores logical values Yes and No. Usually used as the primary keyįour bytes (16 bytes if it is set as a Replication ID). It allows you to store currency values and numeric data with one to four decimal places.Īssign a unique number or assigned by Microsoft Access when any new record is created. Store Date/time for the years 100 through 9999. Numeric data type used for storing mathematical calculations. This data type is used for lengthy text or alphanumeric data. Text, including numbers which does not need calculation. MS Access common data types are listed below: Type of Data Modules are procedures(functions) which you can write using Visual Basic for Applications (VBA). They allow you to set up commands and processes in your forms, like, searching, moving to another record, or running a formula. Macros are mini computer programming constructs. You can even customize the report’s look and feel.A report is an object in desktop databases primarily used for formatting, calculating, printing, and summarizing selected data.It mainly used to ease the process of data entry or editing. Forms help you to display live data from the table.A form is a database object that you can use to create a user interface for a database application.Types of Query can be SELECT, INSERT, UPDATE, DELETE.Queries can pull from one or more related Tables and other Queries.Queries show a selection of data based on criteria (limitations) you provide.Queries answer a question by selecting and sorting and filtering data based on search criteria.We can also define Primary Key in a table.A Table is usually related to other tables in the database file.A Table is an object which stores data in Row & Column format to store data.Every field has one datatype like text, number, date, etc. Photo Credit: Maksim Kabakou /Shutterstock.Datatypes are the properties of each field. Keep up with “paperless” consumer demands.Organize and track customers, inventory, and employees.“The monitoring, administration and maintenance of databases and database groups across an enterprise.” ( Oracle).Processes around “Sharing, storing, protecting and retrieving an ever-increasing amount of data.” ( AICPA).“Different Data Models currently used to structure the logical view of the database: relational, hierarchical and network.” ( Department of Computer Sciences, University of Wisconsin-Madison).Users of the system are given facilities to perform several kinds of operations on such a system for either manipulation of the data in the database or the management of the database structure itself.” ( IBM) “Administration tasks pertaining to managing records, storage space and backups.” ( Microsoft Technet).Database management is categorized by their basic structures, to some extent, by their use or deployment.” ( Gartner) A “product used for storage and organization of data that typically has defined formats and structures”.Other Definitions of Database Management Include: Blockchain: A type of federated database system used to securely manage financial and other types of transactions.Tightly Coupled: Component systems use independent processes to construct and publish into an integrated federal schema.Loosely Coupled: Component Databases construct their own federated schema and typically requires accessing other component database systems through a multi- database language.Federated Databases can be categorized as: This kind of Database Architecture is best for heterogenous and distributed integration projects. It maps multiple autonomous databases into one large object. Federated: Provisions data without additional persistence or duplication of source data.“Rather than rely on hardware to deliver high-availability, the Database Management software…is designed to replicate data amongst the servers” allowing it to detect and handle failures. Distributed: Data resides over a variety of nodes, making quick access possible.All users come to that one system to access the data. Centralized: all the data lives in one system in one place.Database Management Systems, according to the DAMA DMBOK, include various types: Managing a database involves designing, implementing and supporting stored data, to maximize its value. Database Management can also describe, the data storage, operations and security practices of a Database Administrator (DBA), throughout the life cycle of the data. Database Management, allows a person to organize, store and retrieve data from a computer.
