HTML, CSS:- HTML is the standard markup language for creating Web pages.

Microsoft Access is a database management system (DBMS) from Microsoft that combines the relational Microsoft Jet Database Engine with a graphical user interface and software-development tools. It is a member of the Microsoft Office suite of applications, included in the Professional and higher editions or sold separately.
Microsoft Access stores data in its own format based on the Access Jet Database Engine. It can also import or link directly to data stored in other applications and databases.
Software developers, data architects and power users can use Microsoft Access to develop application software. Like other Microsoft Office applications, Access is supported by Visual Basic for Applications (VBA), an object-based programming language that can reference a variety of objects including the legacy DAO (Data Access Objects), ActiveX Data Objects, and many other ActiveX components. Visual objects used in forms and reports expose their methods and properties in the VBA programming environment, and VBA code modules may declare and call Windows operating system operations.
Photoshop is a raster graphics editor developed and published by Adobe Inc. for Windows and macOS. It
was originally created in 1988 by Thomas and John Knoll. Since then, this software has become the industry standard
not only in raster graphics editing, but in digital art as a whole. The software’s name has thus become a generic trademark, leading to its usage as a verb (e.g. “to photoshop an
image”, “photoshopping“, and “photoshop contest“) although Adobe discourages such use. Photoshop
can edit and compose raster images in multiple layers and supports masks, alpha compositing, and several color models including RGB, CMYK, CIELAB, spot color, and duotone.
Photoshop uses its own
PSB file formats to support these features. In addition to
raster graphics, this software has limited abilities to edit or render text
and vector graphics (especially through clipping path for the latter), as well as 3D graphics and video. Its feature set can be expanded by plug-ins; programs developed and distributed independently of
Photoshop that run inside it and offer new or enhanced features.
